Sil assessment Risk Graph and LOPA Training iFluidsJohn Kingsley
LOPA is the newest methodology for hazard evaluation and risk assessment. On a sliding scale of sophistication and rigor, LOPA lies between the qualitative end of the scale (characterized by methods such as hazard and operability, or HAZOP, analysis and what-if analysis) and the quantitative end (characterized by methods using fault trees and event trees). LOPA helps the analyst make consistent decisions on the adequacy of existing or proposed layers of protection against an accident scenario. The technique is ideally suited for companies striving to meet specific risk targets or to lower risk as low as reasonably practicable (ALARP).

Safety is an important consideration in process design. Safety integrity level (or SIL) is often used to describe process safety requirements. However, there are often misconceptions or misunder- standings surrounding SIL. While the general subject, functional safety and SIL, can be highly technical, the general ideas can be distilled down to a few readily understandable concepts. In this paper, we will discuss what SIL is, why it is important, what certification means, and the implications and benefits of that certification to the end user.

NUMERICAL SIMULATIONS OF HEAT AND MASS TRANSFER IN CONDENSING HEAT EXCHANGERS...ssuser7dcef0
Power plants release a large amount of water vapor into the
atmosphere through the stack. The flue gas can be a potential
source for obtaining much needed cooling water for a power
plant. If a power plant could recover and reuse a portion of this
moisture, it could reduce its total cooling water intake
requirement. One of the most practical way to recover water
from flue gas is to use a condensing heat exchanger. The power
plant could also recover latent heat due to condensation as well
as sensible heat due to lowering the flue gas exit temperature.
Additionally, harmful acids released from the stack can be
reduced in a condensing heat exchanger by acid condensation. reduced in a condensing heat exchanger by acid condensation.
Condensation of vapors in flue gas is a complicated
phenomenon since heat and mass transfer of water vapor and
various acids simultaneously occur in the presence of noncondensable
gases such as nitrogen and oxygen. Design of a
condenser depends on the knowledge and understanding of the
heat and mass transfer processes. A computer program for
numerical simulations of water (H2O) and sulfuric acid (H2SO4)
condensation in a flue gas condensing heat exchanger was
developed using MATLAB. Governing equations based on
mass and energy balances for the system were derived to
predict variables such as flue gas exit temperature, cooling
water outlet temperature, mole fraction and condensation rates
of water and sulfuric acid vapors. The equations were solved
using an iterative solution technique with calculations of heat
and mass transfer coefficients and physical properties.

Safety ?
Why should we invest in safety?
‣ You think safety is expensive, try an accident…
‣ Today an accident cost more than 10x the investment in the process
‣ We have had terrible accidents in the past
‣ We learned, but accidents with serious impact still happen today
8. 88
Safety Integrity Level - SIL
SIL is how we measure the performance of safety functions
carried out by safety instrumented systems
SIL has 3 sides to the story
‣ Process owners:
Which safety functions do I need and how much SIL do I need?
‣ Engineering companies, system integrators, product developers:
How do I build SIL compliant safety devices, functions or systems?
‣ Process operators:
How do I operate, maintain and repair safety functions and
systems to maintain the identified SIL levels?
10. 1010
SIL levels
Most famous SIL requirement is the Probability of Failure on Demand
PFDavg = Probability of Failure on Demand average
11. 1111
Functional Safety
A safety instrumented system is 100% functionally safe if
All random, common cause and systematic failures do not lead to
malfunctioning of the safety system and do not result in
‣ Injury or death of humans
‣ Spills to the environment
‣ Loss of equipment or production
‣ 100% functional safety does not exist but SIL 1, 2, 3 or 4 does
12. 1212
Common cause does not happen?
Complete plant flooded
because of heavy rainfall,
bad drainage and dike
18. 1818
What is the difference between a normal safety and SIL3 loop?
• SIL 1 Typically easy to achieve using standard components
• Through the selection of certified components, can achieve SIL 2 with
single channel sensing or final elements
• Still need to consider the systematic capability for the devices, however
these are less stringent for SIL 1 or 2
• Lifecycle cost typically the same as a normal BPCS loop.
NORMAL LOOP
BPCS = Basic Process Control System
19. 1919
• Redundancy requirements for sensing and final elements
Required by Tables 2 and 3 of 61508-2. Based on SFF
Safe Failure Fraction = A measure of the effectiveness of the fail safe design and/or the built-in diagnostic tests
Depending on the logic solver, can be single channel
• Proof Test Coverage can be a limiting factor
• Systematic requirements higher
Requires careful selection of devices to ensure this is achieved.
May rule out your normal supplier
• Life cycle cost much higher
What is the difference between a normal safety and SIL3 loop?
SIL 3 LOOP
20. 2020
• The higher the SIL the more techniques and measures are required to
detect, control and avoid human error
• SIL 1 Typically easy to achieve using a standard QMS system with added
competence requirements
• SIL 2 requires an “advanced” system with competence management and
reliance on testing
• SIL 3 has stringent requirements governing diversity in design,
competence of a high order and stringent testing requirements
What is the difference between a normal safety and SIL3 loop?

Layers of protection
Specific
• must be specifically designed to be capable of preventing the consequences of the
potentially hazardous event
Independent
• must be completely independent from all other protection layers
Dependable
• must be capable of acting dependably to prevent the consequence from occurring
(systematic and random faults)
Auditable
• must be tested and maintained to ensure risk reduction is continually achieved
27. 2727
Layers of protection – The 3 “ENOUGHS”
• Big Enough
• Must be big enough to cope the with the potential hazard
• Fast Enough
• Must be fast enough to sense and react to prevent the potential
• Strong Enough
• Must be able to survive all arising situations when preventing the hazardous
event.
28. 2828
Are you safe if you buy a SIL3 PLC?
• NO!!!
• Need to consider Sensing and final elements
• Need to consider Systematic Capability
This applies to the integrator of the Logic Solver – important to look at their
quality system
Apples to the installer of the Safety Integrated Functions – important to look
at their quality system
• Need to carefully consider Proof Test Intervals and Proof test coverage
Short proof test intervals should be avoided as the testing requirements
often require plant shutdown
Incorrect to assume that the proof test is perfect
This can have a profound effect on the result because we are dealing with
very small numbers
29. 2929
Safety & non safety in one application or separate
safety and non-safety
• Considerations for separating:
Hazards are caused by the non safety application
Risk assessment not able to separate the causes
Required by Buncefield recommendation 3
– “physical and electrical independence”
Need for Cyber security
• Considerations for systematic capability!!!
Often the same person programming the non-safety will be programming
the safety!
