Driving Combined Cycle Efficiency Gains

Jim Cahill

Combined cycle electrical power generation facilities play an essential role in providing baseload power to the grid. The principle of operation : …is that after completing its cycle in the first engine, the working fluid (the exhaust) is still hot enough that a second subsequent heat engine can extract energy from the heat in the exhaust. Usually, the heat passes through a heat exchanger so that the two engines can…

Control Valves in Safety Instrumented Functions

Jim Cahill

A reader of this blog came upon the post, When is a SIL Suitability Rating Required for Final Control Elements? The reader sent an email to the blog post author, Emerson’s Riyaz Ali , asking (of which I’ll paraphrase): When is it possible to use control valves like final elements for SIS [safety instrumented system] application? I am looking for other useful documents and technical requirements when it is possible to…

Valve Reliability in Safety Instrumented Functions

Jim Cahill

The three key components in a safety instrumented function (SIF)—sensor, logic solver and final element—each have their own probabilities of how they will perform, or not perform, when called upon to bring the process to a safe state. Of these three components, the final element is more like to fail on demand due to its role in touching the process and mechanically operating. In a Hydrocarbon Engineering article, Improving…
