This document discusses challenges facing the U.S. petrochemical industry and strategies for improving plant design, operation, and maintenance. It argues that most plants are not designed or operated efficiently and will struggle to be profitable long-term given industry pressures. To survive, plants must focus on energy efficiency and reliability, especially of rotating equipment, through techniques like pinch analysis and variable speed drives. Advanced process control using extensive sensor data can help optimize plant performance, though initial costs are high. Overall the industry needs an integrated approach considering the entire asset lifecycle from design through maintenance.

Future Trends - Recycling - Demolished Construction MaterialsBruce LaCour
This transition where many essentials become less abundant and more expensive won’t be accepted as permanent by many; however, those that make the transition swiftly will quickly move to many areas of recycling. These will be some of the business survivors I have referred to in earlier articles. One of the biggest recycling movements will be deconstruction and using recovered materials for different uses.
Part of the future of recycling will be innovative efforts to use the recycled materials. The trash-throw-away society has to make the transition from the Age of Growth into the Age of Survival before that happens to any great extent. The younger generations will lead the way once they realize the past cannot be revived.
Recycling electrical wire may not be a multi-million dollar market in the future, but it will be a living!
Even if the value of recycled glass increased in the future, there would still be the technical problem of separating glass from other recyclables at the Material Recovery Center. If glass ever becomes a significant recyclable, it will be done by companies that specialize in collecting and recycling glass separately from the bulk of the trash generated by the trash society.
Future Trends - Recycling - Metals - Part IBruce LaCour
Mining has to return to the United States. The U.S. is not just running low on economically recoverable oil and gas, but also vital minerals at an even faster rate.
The U.S. Baby Boomer mirage has been kept the importers of “stuff” into the United States with positive trade deficits happy. That is coming to an end.
Future Trends - Recycling - Material Recycling FacilitiesBruce LaCour
Eventually, non-organic waste will be a big business, and recycling will be one of the ways to recover the cost of creating, collecting, and sorting the waste created by communities. The launching point for this business will be the Material Recovery Facility.

Implicitly or explicitly all competing businesses employ a strategy to select a mix
of marketing resources. Formulating such competitive strategies fundamentally
involves recognizing relationships between elements of the marketing mix (e.g.,
price and product quality), as well as assessing competitive and market conditions
(i.e., industry structure in the language of economics).
US Petrochemical Industry Future - Integrating Design Operation and Maintenance
1. U.S. PETROCHEMICAL INDUSTRY FUTURE – INTEGRATING
DESIGN, OPERATION, AND MAINTENANCE
Page 1 of 10
When a petrochemical company decides to build a plant, the operating company is buying
someone else’s process technology usually. That technology is most likely going to be identical
or similar to the operating company’s competitors, even if it is a different design variation. Some
like to think they have a design advantage; however, the only operational advantage they may
have has nothing to do with the design of the plant. In any case, design variations are overrated.
The usual case is the initial price is right. Let’s start prospecting Alaska before the gold rush
fizzles.
My opinion is that the usual upper management is more concerned with the overall schedule of a
new plant from front end design to construction completion and startup than the efficiency of the
design. It makes sense since they know their plant isn’t any more efficient than the competitor’s
recent addition, and the emphasis is getting the plant up and running at 100% of design capacity
per original schedule. I learned that quickly with my first job in a petrochemical plant. An
experienced Plant Manager will tell you whatever you don’t like can be possibly changed later
via an approval capital budget. His job is to get the plant (investment) making product(s)
(money), not to make the plant personnel happy about the initial condition of the plant now or in
the future.
Often many future considerations are overlooked during the latter part of construction due to the
haste to start production. Maybe that has changed a little bit nowadays, but I doubt it.
Maintenance starts on day one of operation where it become clear very fast where the main
operational problem areas will be, and they are usually the most expensive rotating equipment
items.
After the startup, the fun begins and the clock starts ticking on the operating expense side. In the
past, if you were lucky to build during a recession and ready to startup during the initial phases
of economic recovery, than things were honky-dory for a while. Those days are over. Any
petrochemical plants that have started in the last five years have or are planning to start up in
the next five years will experience immediate pressure on the income statement due to stagnant
to falling product prices and/or rising feedstock and energy costs. Recent methanol and
ammonia plant expansions and relocated or new plants are a very good example, and these
ethylene plants are about to join the crowd of less than expected rate of return on initial
investment. LNG plants have less than 10 years life before they are forced to shut down after
depleting decreasing natural gas reserves.
What’s the point so far? The point is that most are on an overcrowded elevator on the way down
fast. The only way they are going to survive the crash is to brace themselves and prepare, and
stop thinking about grow, grow, and grow because they may already be in a deep hole. Just
because feedstock cost is temporarily low, that means nothing if demand isn’t rising like it used
to. When the feedstock cost starts to rise do to the overcrowded playing field and later due to
uneconomical feedstock cost, than the plant will become a major burden. From then on, it will be
a constant struggle to make a profit. The first tactic will be to cut manpower to the minimum, and
they better be ready to operate with the minimum staff. I explained one way survivors will use in
2. U.S. PETROCHEMICAL INDUSTRY FUTURE – INTEGRATING
DESIGN, OPERATION, AND MAINTENANCE
Page 2 of 10
“U.S. Petrochemical Plant Future – Flexible Labor”. Future operation must utilize still other
survival tactics different from the past “good-ole days” of operation, which I partially explain in
“The Future of Engineering Consulting”.
The survivors will have to be one of the most cost efficient operations in the industry in order to
be still operating ten years from now. Most will grow themselves an early grave due to excessive
debt accumulation. Labor reduction is the easiest way to reduce cost, and just read the news to
see that is already in progress in all areas of the economy. Simultaneously to initiating labor
reduction, the surviving petrochemical industry has to be much more energy efficient.
The future will be all about energy conservation in your particular sector of the petrochemical
industry. And guess what? It doesn’t come from hiring the “experts” with the latest buzz words
like reliability engineering, mechanical integrity, sigma-six, and all the rest concerned with
prolonging assets that probably have a short-term life anyway. What do I mean by that?
This “trash society” based on planned obsolescence and “plastics gone wild” mentality is
doomed. There is not enough economically priced fossil fuel feedstock in existence to keep this
suburban, happy motoring, more-stuff-to-throw away lifestyle going for another ten years. So
why spend money on the programs and the manpower to keep fixed assets based on a
continuation of the Baby Boomer age operational for 30 to 40 years? That is what is what these
experts are trying to do with all these “reliability” and latest maintenance (reactive to preventive
to predictive and now reliability-centered) acronym programs. From LNS research:
What Comes After Predictive Maintenance?
Posted by Dan Miklovic on Thu, Mar 17, 2016
I have been in the Asset Performance Management (APM) space for over 45 years now, and
certainly have seen the long and slow evolution that has taken place as we have moved away
from purely reactive maintenance to a point where the standard practice is PM. With the growth
of programmable logic controllers (PLCs), distributed control systems (DCSs), and digital
communications in the late 1980’s through the 1990’s, condition-based maintenance (CBM)
started the shift towards predictive maintenance. The onset of statistical analysis tools in the
last15-20 years has enabled reliability-centered maintenance (RCM). Yet, all of these
advances have come at a relatively slow pace. Part of the reason for that has simply been the
cost-benefit ratio has been low enough that it is difficult to justify the investment.
That’s right! 45 years ago reliability-centered maintenance might have made sense in a new,
growing U.S. petrochemical industry. Why didn’t past management invest more in maintenance?
Anyone know the answer? Because the top brass didn’t think the plant would be running for 40
to 45 years hence. Plus the CEO and Vice Presidents certainly wouldn’t be in charge then. It
was, and still is, about fast payback, high return on investment, running up the earnings per
share short-term (just long enough for the tenure of the present CEO and his/her EPS-related
bonus plan). It is too late to apply reliability maintenance carte blanche to the mature
petrochemical industry. It has to be applied where return is most noticeable and benefit is

DESIGN, OPERATION, AND MAINTENANCE

immediate. That isn’t easy, and the worst thing you can do is hire a lot of long term liabilities to
try to find it.
So what am I suggesting? Go back to the reactive maintenance? No, just apply that to the fixed
assets, with very few exceptions in key, highly corrosive or fouling environment fixed assets. The
rotating assets are where both energy savings design and reliability is important. Again, what am
I getting at? What is the largest variable operating expense in any plant next to feedstock cost?
Electricity is the next biggest variable expense either purchased or self-generated using natural
gas, which may also be your feedstock (hence total reliance on natural gas). This is the area you
need to concentrate on maximizing both reliable performance and energy efficiency. Why?
How?
Every plant has either liquid pumping circuits or gas or vapor (steam usually) flow circuits with
rotating equipment (pumps for liquid, compressors for gas, and steam turbines for steam) either
initiating or utilizing the flow. Also, in these circuits are various types of heat exchangers
exchanging heat between circuits. Here is where energy is wasted! Why?
Because the circuits are either designed only for steady-state design production rates and/or
minimum first cost. This new combination of buzz words, pinch analysis, is a way of getting the
maximum out of your heat exchange networks. From Wikipedia:
Pinch analysis is a methodology for minimising energy consumption of chemical processes by
calculating thermodynamically feasible energy targets (or minimum energy consumption) and
achieving them by optimising heat recovery systems, energy supply methods and process
operating conditions. It is also known as process integration, heat integration, energy
integration or pinch technology.
The process data is represented as a set of energy flows, or streams, as a function of heat load
(kW) against temperature (deg C). These data are combined for all the streams in the plant to
give composite curves, one for all hot streams (releasing heat) and one for all cold
streams (requiring heat). The point of closest approach between the hot and cold composite
curves is the pinch point (or just pinch) with a hot stream pinch temperature and a cold stream
pinch temperature. This is where the design is most constrained. Hence, by finding this point
and starting the design there, the energy targets can be achieved using heat exchangers to
recover heat between hot and cold streams in two separate systems, one for temperatures
above pinch temperatures and one for temperatures below pinch temperatures. In practice,
during the pinch analysis of an existing design, often cross-pinch exchanges of heat are found
between a hot stream with its temperature above the pinch and a cold stream below the pinch.
Removal of those exchangers by alternative matching makes the process reach its energy
target.
What pinch analysis will probably do with the initial design is add up front engineering and
capital cost but increase long-term operating efficiency (energy efficiency). Concentrating further

on rotating equipment reliability in the design phase will synchronize with this idea. Returning to
Miklovic’s article, he says something I agree with:
Yet, all of these advances have come at a relatively slow pace. Part of the reason for that has
simply been the cost-benefit ratio has been low enough that it is difficult to justify the investment.
First it was the cost of the sensors, but digitization drove that down over time. Then it was the
cost of connection, but wireless has driven that down. After that it was the cost of configuration,
but self-aware device shave driven that down. Analytics were difficult because a deep
understanding of statistical methods and domain expertise was scarce. Today’s analytical
engines, developed by vendors to address the big data issues associated with customer data
and the proliferation of data scientists at most suppliers, has now made the analytics barrier a
moot point.
In essence we have reached the tipping point. The convergence of the IIoT, Cloud, Big Data and
Analytics, all facilitated by the growth of smart handheld devices. Enabling mobility has created
the perfect storm that will drive shifts over the next three plus years. So, by 2020 when self-
driving cars become a common sight, although not the majority of cars on the road, a new model
of maintenance driven by Smart Connected Assets will emerge.
True, just apply this technology where it counts and has the quickest payback because your
plant probably isn’t going to be running twenty years after startup.
Other than pinch analysis to optimize heat exchanger network design, what else can be done? I
wish I had this technology in an affordable package in the 1970s – variable speed drives. What
the 1970s plants had, and many now still have, were a lot of control valves wasting the energy
that the old relatively inefficient motors of that day generated. Even though the plants are
designed to operate at design rate and should be operated there for maximum efficiency, there
are many situations that require operation below design where the control valves start closing,
wasting even more energy.
Variable speed of rotating equipment is an area that should be maximized. It doesn’t always
have a sufficient payback (read all about it), but all the economical possibilities should be
utilized. This is even more important because pinch analysis will probably add heat exchangers
and add pressure drop in the flow circuit requiring additional rotating equipment energy
consumption. It always comes down to first cost versus time-based energy savings. The past
low energy cost environment was part of the cause for delay in many energy savings revisions.
The initial cost of all these new ideas were just too burdensome for the upper management
fixated on this year’s and next year’s EPS. Nothing has changed that operating philosophy.
However, the future players will have to save every Btu or kW possible just to play the game.
In the mid-1970s, I was a “Production Engineer” in a petrochemical plant. We didn’t have fancy
titles. My job assisted by the one “Maintenance Engineer” was operation, reliability,
maintainability, cost reduction, “Sigma-Six”, and preventive, predictive, proactive maintenance;
and any other BS buzzword you could think of. I was also the Project Engineer. My main job was
5. U.S. PETROCHEMICAL INDUSTRY FUTURE – INTEGRATING
DESIGN, OPERATION, AND MAINTENANCE
Page 5 of 10
to monitor the daily performance of one of the two plants producing the same main product. I
was also supposed to recommend improvements annually. I quickly realized that I better know
what makes that clock tick and proceeded to learn the nuances of the operation down to every
piece of equipment’s normal operating envelope.
One night at two in the morning, I get a call from the Production Manager that one of the
distillation columns is not operating on spec. Specifically, the overhead composition contained
too much of a heavy component that would buildup down the line in the process and cause
major problems eventually. He had been on the phone with the Shift Supervisor trying to correct
the problem. He had the Shift Supervisor increase reflux flow to reduce the heavy component in
the overhead. It wasn’t working. He wanted me to go out to the plant and help them correct the
problem as fast as possible.
I get there and look at the reflux flow and notice right off the bat that it is way too high. How
come the overhead has too much heavies? I don’t know, but what I did know is that a small
range of reflux given a normal feed composition is where this column operated with no problems
for months.
I tell the Shift Supervisor to order a significant decrease in reflux back to the normal reflux flow I
would see every day that I studied the operator logs, which was every working day young
Pilgrims. He wanted to call the Production Supervisor. I said “no, just do it; I’ll take
responsibility.” Within one hour, the overhead composition was back to normal. I immediately
called the surprised Production Supervisor and told him the problem was solved. Apparently, he
didn’t believe me, and probably was concerned I didn’t consult him first. He spoke to the Shift
Supervisor, who confirmed the solution.
Now I am a young Mechanical Engineer and the Production Supervisor was a much more
experienced Chemical Engineer and the Shift Supervisor had been there at least six years. What
did I have, they didn’t? Data!!!!!! It is no coincidence that Gene Roddenberry named his superior
than human android in Star Trek Next Generation – Data. Old Gene knew about the future, I am
sure.
Now what caused the incidence of abnormally high heavies in the overhead to appear in the first
place? I don’t know – a change in feed composition (confirmed later not the case), bad overhead
sample analyses, or the board operator letting the control get away from him in between log
entries (they were written down at fixed intervals in those days)? Who cares, I didn’t. I was soon
headed back to my bed. You see, this is what one of the latest buzz word combinations is all
about – advanced process control. These guys always think they have come up something new!
From Wikipedia:
In control theory Advanced process control (APC) refers to a broad range of techniques and
technologies implemented within industrial process control systems. Advanced process controls
are usually deployed optionally and in addition to basic process controls. Basic process controls
are designed and built with the process itself, to facilitate basic operation, control and
6. U.S. PETROCHEMICAL INDUSTRY FUTURE – INTEGRATING
DESIGN, OPERATION, AND MAINTENANCE
Page 6 of 10
automation requirements. Advanced process controls are typically added subsequently, often
over the course of many years, to address particular performance or economic improvement
opportunities in the process.
Advanced process control is a computer program designed to take data via numerous sensors,
apply it to process equations, and keep certain pressures, temperatures, flows, levels, and flow
compositions within control limits much better than these minimally technically educated, trained
mostly by experience only board operators can do, even if they have been there 30 years. What
miraculous new advances in technology!! Eventually, even better artificial intelligence will take
over the job.
Whatever is running the show down the road, data is what is needed and sensors are what
deliver the data. As Miklovic says:
Part of the reason for that has simply been the cost-benefit ratio has been low enough that it is
difficult to justify the investment. First it was the cost of the sensors, but digitization drove that
down over time. Then it was the cost of connection, but wireless has driven that down.
Wireless technology is available now, and it will be used more extensively in the future.
Emerson, Honeywell, and others are pushing it because they always lead the way. The
operating companies follow, if they are smart. The initial design should maximize the use of
wireless and use other technology available that limits the ridiculous amount of instrument wiring
in these old plants. The key point is there is no such thing as too much data, just wrong or
technically deficient interpretation of it or data you can’t afford to get.
I can give you many more examples of where data is important similar to the above, but you get
the idea. Energy conservation in these plants is not a complicated subject. Much can be done
with relatively minimum capital investment and minimum staff, and I explain all that in one of the
reports, “Energy Conservation – The Easy Stuff”. The easy stuff is the place to start, but it won’t
be enough.
Recent advances in simulation software are the next thing to investigate, and its use should be
decided before a plant is commissioned because it involves coordination starting at the design
phase of a new plant. Trying to add the simulation after startup will involve additional monitoring
devices and other costs which make the total cost difficult to justify, especially for an older plant
that is struggling to survive the latest economic recession. Don’t throw good money after bad!
The two areas that most impress me that I certainly could have used in the 1970s are electrical
and mechanical “design-analyze-operate” software. I’ll start with the electrical software that
probably is the most useful. This partnership of Intergraph’s “SmartPlant” Electrical and “ETAP”
resulting in a bi-directional interface between design and operation is an excellent idea. If you
are involved in operation and maintenance of a plant, it is waste of space to explain the benefits
of knowing how the all too invisible electrical system is functioning in real time. Also, a method of
training and responding to the unexpected is valuable information to keep the plant running,

DESIGN, OPERATION, AND MAINTENANCE
Page 7 of 10
which you are employed to do, by the way. You are going to need to invest in electrical sensor
equipment to make this worthwhile. You can read (or hear) all about it in “ETAP” videos.
The other interesting area for those who believe fixed asset longevity will pay off for them is the
direction Codeware is going in with “Inspect”. The refining industry is really into this Fitness for
Service movement, which started without a name in the 1980s and gained momentum starting in
2000 with the first edition of API 579. From an article “Recent Advances in Fitness-For-Service
Assessment”:
Ted Lynn Anderson Quest Reliability, LLC Boulder, Colorado, USA
1 Executive Summary
Fitness-for-service (FFS) assessment is a multi-disciplinary approach to determine, as the name
suggests, whether a structural component is fit for continued service. In 2000, the American
Petroleum Institute (API) published API 579, a Recommended Practice for FFS assessment.
Although this document was intended primarily for refining and petrochemical assets, it has seen
widespread use in a wide range of industries that utilize pressure vessels, piping, and storage
tanks. In 2007, API joined forces with the American Society for Mechanical Engineers (ASME) to
produce an updated document with the designation API 579-1/ASME FFS-1. This document,
which is a Standard rather than a Recommended Practice, contains numerous improvements
and explicitly addresses industries outside of refining and petrochemical.
The movement is now a “popular cause” almost with the API developed programs for
certification.
API 510 – Certified Pressure Vessel Inspector
API 653 – Above Ground Storage Tank Inspector
API 570 – Authorized Piping Inspector
This movement is out of control just like the ASME and API increasing proliferation of
recommended practices and standards trying to justify their continued existence. All movements,
especially well intentioned ones, eventually become expanding bureaucracies with self-
promoting reasons for their existence in your organization, industry, community, or country.
Therefore, let us create new buzz words and more reasons to hire employees that weren’t
needed heretofore. Let us not ask why we need this; however, let us jump on the latest
bandwagon. Everyone else is so it must be right for us.
For instance, the proliferation of adds for “Reliability Engineers” and “Mechanical Integrity
Engineers” seems to be a relatively recent realization of something, which I don’t understand
given the future prospects for petrochemical industry longevity. A typical add is as follows (the
head hunter spelled integrity as intergrity):

Now get as many headhunters looking for someone with all these qualifications (which are few
by the way). Of course, getting the head hunters to understand what they are looking for first
requires that that the requester understand what he or she is looking for and why. It takes a lot of
time and a lot of money spent to get all this training so you think you are going to find these
individuals growing on trees? The 5 years + experience requirement is really the most
laughable. You know they don’t each this stuff in engineering school?! How about 15 years +
being more like it?
Now the expertise exists out there, but they are usually found in the organizations that started
the movement in the first place in order to create a before-then nonexistent market. There is no
need to hire someone with these qualifications when you can get someone a great deal more
experienced on a contract basis and as needed. I say as needed because the first to go when
the “Brass” says cut back are the highest paid and the ones who aren’t absolutely needed to
keep the plant running, which is just about everyone not in an operational role. With contract
personnel you don’t have to worry about the inevitable economic downturn, which always results
in depopulation of the organization. This is a lesson that never seems to be learned.

I’m all for this reliability movement in the refining industry because some of these refineries will
still be running 30 years from now. However, most of the petrochemical industry should get off
the latest industry hypemobile and understand where they are going with this movement. I think
the surviving petrochemical industry will be about specialty and smaller and probably short lived
ventures and facilities. Plus they will eventually have to move into the new biochemical industry
with new facilities. These billion dollar basic chemicals mega plants have as much chance of
existing 20 years from now as a snowball in hell. Where is the feedstock going to come from?
And if you can get it, will the resulting profit be worth all the constant large capital investments
required? I am certain it won’t be worth it in the not too distant future.
Having said all this, I am impressed with some of the software out there that has to chance to
make this fitness for service movement worthwhile in some cases. Codeware has been
producing mechanical design software for some time with “Compress” for pressure vessel
design and heat exchanger mechanical design. They have moved into the “asset integrity”
movement with “Inspect”. Just like the Smart Plant Electrical-ETAP marriage, “Inspect” is
coordinating with “Compress” initial design to keep a running picture of the life of not only
pressure vessels and heat exchangers but also piping and storage tanks. If you are serious
about the “long-term” benefits of maintaining plant assets, than you have to start at the design
step and provide enough data to maintain those assets throughout whatever life you think you
have. Otherwise, you just temporarily jumped on the latest hypebus, and the next all out stop is
rapidly approaching.
The next movement of interest is the power management, energy management movement,
which is about 50 years too late. However, it is better late than never. There are too many
players in this field trying to provide the answers for controlling and maximizing the efficiency of
electrical and/or total energy consumption to describe one. The key here is do you have a fuzzy,
warm feeling about the longevity of your venture? If not, than this isn’t going to do you any good!
If yes, than definitely look into this movement. However, if you are going to create a bureaucracy
to make it work, than whatever effort you start is doomed. Look at how the U.S. Department of
Energy has tried to make the U.S. safe for tomorrow – one boondoggle after another followed by
one fairy tale after another. In another words, they usually propose a total waste of money on a
large scale that could have been spent on many smaller scales preparing for the future.
The question should be: Is this cost effective for my organization given what I should understand
about the future prospects of my business? The future trend will be toward much smaller plants
as the mega plants become uneconomical to operate and end up as large metal recycle
operations. Believe it or not! I’m looking for those who can see into the future and accept what
they see.
