About your instructor:
I majored in Chemical Engineering with a minor in Industrial Engineering back in 2012.
I worked as a Process Design/Operation Engineer in INEOS Koln, mostly on the petrochemical area relating to naphtha treating.
There I designed and modeled several processes relating separation of isopentane/pentane mixtures, catalytic reactors and separation processes such as distillation columns, flash separation devices and transportation of tank-trucks of product.
Packed columns are used for distillation, gas absorption, and liquid-liquid extraction. They have continuous gas-liquid contact through a packed bed, unlike plate columns which have stage-wise contact. Packed columns depend on good liquid and gas distribution, and have lower holdup but higher pressure drop than plate columns. This document provides details on packed column components, design procedures such as selecting packing and determining height, and examples of absorption and stripping processes in packed columns.
The document discusses key concepts in multicomponent distillation including:
- Key components are chosen to indicate separation and are always distributed between products.
- The Fenske equation is used to determine minimum number of stages assuming constant relative volatility, while the Underwood method determines minimum reflux ratio.
- The Gilliland correlation estimates actual number of stages given operating reflux from minimum values.

The document provides information about an upcoming lecture series on conceptual design of distillation, absorption and stripping systems. It includes the following:
- Details about the lecture topics which will cover fundamentals of binary distillation, types of distillation columns, and design of distillation columns.
- The timetable for lectures and exercises, including assignment dates and topics that will be covered in the exercises.
- Notice that the documents are only intended for students participating in the lecture series at Brno University of Technology.

This document summarizes flooding in a distillation column. Distillation separates mixtures based on differences in volatility through boiling and vaporization. Flooding occurs when excessive vapor flow carries liquid up the column, reducing efficiency. It can be detected by increases in differential pressure and decreases in separation. The document describes an experiment where a distillation column's reboiler heat was incrementally increased. Measurements from pressure transmitters showed that filtering and monitoring standard deviation of the pressure signal could provide early detection of the column approaching flooding. This allows operators to make adjustments and prevent loss of separation and reduced efficiency.

Conclusion
This document discusses reflux ratios in distillation columns. It defines total, minimum, and optimum reflux ratios. Total reflux uses all overhead vapor as reflux, allowing calculation of minimum required plates. Minimum reflux is the maximum ratio requiring infinite plates for desired separation. Optimum reflux minimizes total costs by balancing fixed costs that decrease with higher reflux against increasing operating costs.
Distillation is the basic and oldest chemical separation process used in the chemical industries and petroleum refining.

Basics of two phase flow (gas-liquid) line sizingVikram Sharma
This document discusses two-phase flow line sizing for liquid-gas flows in piping systems. It describes the different flow regimes that can occur using Baker's flow regime map. The key steps outlined are: 1) determining the flow regime based on fluid properties and flow rates, 2) calculating pressure drops for the liquid and gas phases separately using correlations, 3) using a multiplier to determine the two-phase pressure drop based on the flow regime, and 4) summing pressure drops from friction, elevation changes, and fittings to obtain the total pressure drop. Care must be taken to size each pipe segment separately as properties and regimes can change along the line.
To promote intimate contact between the vapor and liquid, the distillation column contains internal devices. The internal devices may be grouped into two general categories: Tray-type and Packing-type.
The most widely applied trays in process industries are 1. Bubble cap trays, 2. Sieve trays and 3. Valve trays.

Basic theory and calculation of Distillation which will help to understand Distillation and stage calculation. it will be helpful for students who are studying chemical engineering and fresh engineers in chemical process industries.
Separator sizing and droplet sizes low shear school - 2017Low Shear School
The document discusses different methods for sizing three-phase separators, including retention time theory, droplet settling theory, and fluid carryover specification combined with estimated droplet size distributions. The droplet settling method calculates the separator dimensions based on the cut-off droplet diameter to be separated, while the fluid carryover method is more complex and utilizes inlet and outlet fluid quality specifications along with estimated droplet size distributions. Maintaining larger dispersed phase droplets upstream of the separator can improve separation efficiency by reducing retention time and fluid carryover.
The document describes a distillation system with multiple units including a feed preheater, reboiler, distillation column, bottom product cooler, top product cooler, and condenser. It provides material and energy balances for the system, including flow rates, temperatures, heat duties, and phases of the streams at each component.

Solvent extraction, also known as liquid-liquid extraction, is a method used to separate compounds based on their relative solubilities in two different immiscible liquids, usually water and an organic solvent. It involves transferring solutes from a feed solution to another immiscible liquid called the extract. Solvent extraction was first developed in analytical chemistry and is now widely used in hydrometallurgy and other industries to separate and extract various metals, rare earth elements, and other compounds. Key aspects of solvent extraction processes include the selection of appropriate organic solvents and diluents, extraction equipment like mixer-settlers or columns, and multi-stage counter-current contacting to efficiently separate solutes.

The document describes the lube oil manufacturing process. It discusses four key processes: solvent deasphalting, solvent extraction, solvent dewaxing, and hydrofinishing. Solvent deasphalting uses propane to extract oils from vacuum residues and produce bright stocks. Solvent extraction commonly uses furfural, NMP, or phenol to remove aromatics from lube oil fractions. Solvent dewaxing uses ketone solvents like MEK to crystallize and remove waxy components. Hydrofinishing catalytically reacts undesirable components like sulfur with hydrogen to improve stability. Process conditions and typical yields are provided for each step.
The document discusses industrial wastewater treatment at an oil refinery. It provides an overview of the oil refining process and the various units involved. Significant waste is produced, including hazardous materials in wastewater. Refinery wastewater treatment typically involves oil removal through API separation and dissolved air flotation, followed by equalization and biological treatment using activated sludge. Additional steps like nitrification and denitrification may be used to meet strict nitrogen limits. Proper wastewater treatment is important to meet environmental standards and protect public health from potential health hazards of untreated effluent.
This document discusses the design and processes involved in sludge treatment for wastewater. It begins by defining sludge and its sources.

Plan an ETP with detail process discussion following the instructionsMd Fahimuzzaman
Effluent is the stream of excess chemical liquor from an industry after using in original operation. For example, the excess dye liquor extracted from the textile industry after dyeing is an effluent of that dyeing industry. Effluent Treatment Plant or ETP is a waste water treatment method which is particularly designed to purify industrial waste water for its reuse and it’s aim is to release safe water to environment from the harmful effect caused by the effluent. Textile industry uses numerous hazardous chemicals during processing such as heavy metals, salts, surfactants, sulphite, and formaldehyde, which can cause major pollution in the effluents’ receiving waters. Since textile waste water contains a diversity of impurities and therefore specific treatment technology called ETP is required. The ETP Plant works at various levels and involves various physical, chemical, biological and membrane processes to treat waste water from different industrial sectors like chemicals, drugs, pharmaceutical, refineries, dairy, ready mix plants & textile etc.
1) The document provides important notices for various aspects of daily HPLC use including selecting mobile phases, sample solvents, column temperature, and detection methods.

Koch Modular Process Systems presented on extractive distillation. Extractive distillation involves adding a high-boiling solvent to a binary mixture to alter the relative volatility of the components and allow separation via distillation. It can be considered for mixtures that form azeotropes or have low relative volatility. Examples were given of mixtures like acetone/methanol and THF/water that can be separated through extractive distillation using appropriate solvents. Attendees were encouraged to evaluate extractive distillation for difficult separation challenges.
Enhanced Ammonia Recovery with Built-In Feed Flexibility
Ammonia absorption and recovery projects are not a
unique challenge for the Koch Modular process team. They
have a high level of experience in this area and with an
abundance of existing data, no pilot trials were necessary
to design a solution and then guarantee the ammonia
absorption system performance. However, there were
challenges. The ammonia vapor feed stream was composed
of multiple ammonia-containing streams with a variety of
compositions. The Koch Modular team worked with the
client to agree upon a feed basis for the design of the
system. As often occurs, the ammonia recovery project
was part of an overall major expansion, and the client
requested that the modules be designed to fit indoors both
functionally and spatially into the new facility. This request,
and the overall scale and building configuration presented
some unique design challenges.
Bio-Based Plastic - A Novel Process Solutions Approach for Successful, Lower Cost Scale-Up.
Koch Modular was initially approached for their demonstrated
optimization expertise in reaction, distillation and filtration unit
operations. One of the technical challenges the company faced
was determining how to compensate for changing byproduct
compositions as a result of evolving feedstock selection,
alongside the need to produce a consistent yield of material.
They also requested guidance with engineering services,
process conceptualization and pilot testing in order to take
their revolutionary, small-scale manufacturing to successful
full-scale production.
Product purification and recovery remains a priority for chemical engineers, today. Designing separations processes to accomplish the above is a challenge, especially as streams get more complex in composition. Though often overlooked, liquid-liquid extraction (LLE) is a powerful separation technique for both organic and aqueous liquids. Whereas distillation technology relies on relative volatility differences among chemicals, LLE exploits the differences in relative solubilities of compounds in two immiscible liquids, to perform the key separation. Distillation may not be feasible when boiling points are nearly identical or for other reasons, economic and technical. When distillation is not a viable solution, LLE is a great alternative to achieve product purification and recovery.

Taking a new technology from concept to commercialization can be a daunting process for any company and especially formidable for emerging companies.
Whether you are an established company or a start-up, successfully navigating process development and scale-up challenges can directly impact your ability to achieve critical success factors such as: conceptualization, project funding, pilot testing, design development & optimization, and ultimately construction and start up. Success factors which can directly impact your ability to deliver a commercial-scale production unit on time and on budget while achieving time to market and meeting commitments to your stakeholders.
Chris Rentsch, Process Development Manager at Koch Modular, will walk through Koch Modular’s modularLAUNCH: Delivery Model. Furthermore, he will share real world examples and discuss critical success factors during each phase of process development and the pitfalls to be on the lookout for, which have the potential to sideline your project.
According to the Construction Industry Institute, modularization entails the large-scale transfer of stick-build construction effort from the jobsite to one or more local or distant fabrication shops/yards in order to exploit one or more strategic advantages. Nonetheless, the majority of projects today still do not exploit these strategic advantages to their fullest potential.
Modular Construction has many advantages over conventional stick-build construction. These benefits include shorter schedules, lower cost overall cost, minimal plant site interruption and many more. Strengthen your knowledge of when and why to choose modularization as a project delivery model.

This document discusses a modular construction project called "Chill" that was completed successfully to address scheduling concerns for a larger project. The Chemours company was initially concerned about working with a modular contractor for various reasons relating to space, access, and construction. However, Koch Modular Process Systems was able to address all of Chemours' concerns through their modular design. This included removing temporary steel supports after installation, minimizing interior bracing, and ensuring proper access, egress, and safety features. As a result, the modular facility was delivered ahead of schedule and under budget compared to traditional construction. Chemours was so satisfied that they hired Koch Modular for two additional projects.
A specialty chemical company hired Koch Modular to design and build a modular distillation system to recover spent solvents. Koch Modular engineered a multi-step distillation process using modular units that provided lower energy usage than the existing system. The modular design allowed for expedited fabrication and installation with minimal disruption to plant operations. The new system increased production capacity by 40% to meet growing market demand.
This document discusses various methods for breaking azeotropes in distillation operations. An azeotrope is a mixture that boils as a single composition in liquid and vapor phases, making separation via simple distillation impossible. The easiest type to break is a heterogeneous azeotrope, using a combination of distillation and decantation into separate phases. Pressure swing distillation and azeotropic distillation using an additional entrainer component are effective for homogeneous azeotropes. Other techniques include extractive distillation, liquid-liquid extraction, and newer membrane technologies. Determining the best approach requires substantial experience, as pilot testing is usually needed to account for real feedstock variations not seen in
Equilibrium data and related information gathered from a liquid-liquid extraction laboratory “shake test” can provide information for process feasibility and column-type selection in the scaleup of liquid-liquid extraction processes
Most chemical engineers have had the experience of dealing with problematic separations, and most have a general understanding of distillation processes. When it comes to liquid-liquid extraction (LLE) processes (Figure 1), however, the details of how these processes work are often less clear. Most academic chemical engineering degree programs do not heavily emphasize liquid-liquid extraction, and most chemical engineering graduates did not receive more than a few days of instruction on generating equilibrium data for LLE in their degree programs.
This article describes a project on which Koch Modular Process Systems designed and supplied a distillation system to recover ethylene from an olefins plant purge stream.
KMPS’ engineering team designed a modular acetic acid recovery and purification system as a critical component of a greenfield biomass to renewable chemicals plant.

Glass-lined KARR® Column used for extracting an organic acid from a solvent/monomer feed stream, using water as the solvent. This column is used to extract >90 of the acid prior to neutralization in a second KARR® Column supplied previously, thus minimizing the use of base and generation of salts.
KMPS’ engineering team helped the client design a modular distillation system to recover and purify spent solvents, a process that is vital for the plant’s manufacturing operations. The system was fabricated and delivered under an expedited project schedule to meet a customer specified timeline.
This document discusses the advantages of modular process systems for chemical engineering projects. Modular systems can contain anything from filtration systems to cleanrooms to entire refineries. They are built off-site using industrial techniques, then shipped and assembled on-site. This allows construction to begin before permits are obtained, dramatically reducing project timelines. Modular systems also improve quality control and reduce costs compared to on-site construction. As a result, more complex chemical processes are now being offered using modular approaches.

Advanced control scheme of doubly fed induction generator for wind turbine us...IJECEIAES
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

A review on techniques and modelling methodologies used for checking electrom...nooriasukmaningtyas
The proper function of the integrated circuit (IC) in an inhibiting electromagnetic environment has always been a serious concern throughout the decades of revolution in the world of electronics, from disjunct devices to today’s integrated circuit technology, where billions of transistors are combined on a single chip. The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.

Want the continuous phase to preferentially wet
the internals – this minimizes coalescence and
therefore maximizes interfacial area
For aqueous-organic systems, if water is the
continuous phase, use metal internals,
if organic is the continuous phase, use plastic
internals

Increased agitation speed which forms smaller droplets which cannot overcome flow of
the continuous phase
Decreased interfacial tension – forms smaller drops – same effect as increased agitation

Basic Scale-up Relationships:
D2/D1 = K1(Q2/Q1 )^M1
H2/H1 = K2(D2/D1 )^M2
f2/f1 = K3(D2/D1)^M3
Where:
K1, M1 = Capacity Scale-up Factors
K2, M2 = Efficiency Scale-up Factors
K3, M3 = Power Scale-up Factors
Commercial Scale
“Axial” or “back” mixing increases as an extraction column’s diameter is
increased. This phenomena causes concentration gradients that decrease
driving force and therefore increase HETS.

Editor's Notes
We have been doing Module Construction since the 90’s years before 3rd generation Modularization was even coined.
1979 Schlowsky Engineering established focused on Process Development. Over the years, clients requested services beyond process development expanding our capabilities. As capabilities expanded, we built relationships with technology licensors and grew our expertise from “Ideal” distillation processes to “Non-Ideal” Processes and began delivering complete modularized process systems.
January 1994 Modular Process Systems Inc. Established
January 1999 Formation of Joint Venture Company – Koch Modular Process Systems Joint Venture Partners Modular Process Systems Inc. and Koch-Glitsch
October 2000 Koch Glitsch Contributes Liquid-Liquid Extraction Business and Pilot Plant to the Joint Venture
January 2019 Celebrated 25 Years in Business and the 20 Year Anniversary of the Joint Venture
JV is 1/3 Koch 2/3 Modular Process Systems. Koch doesn’t have an management input not resources imbedded within operations.
