A safety instrumented function (SIF)’s purpose is to reduce the risk of a specific hazard. For example, an upset condition in an oil and gas production separator may cause a series of SIFs within a safety instrumented system (SIS) to shut in the wells feeding the separator. A SIF contains a sensor, logic solver and […]

David Leavitt described an application of high-cycling valves in a dehydration process at the Offshore Technology Conference (OTC) in Houston, Texas. I recapped his presentation last week in a post, Triple Offset Valves and Molecular Sieve Adsorption Applications. He compared rising stem ball valves and triple offset valves (TOVs) used in these applications. David describe […]
