When a refinery in South America was approaching its scheduled three-year maintenance shutdown, it decided to take advantage of the information provided from its intelligent solenoid valves. Earlier, the refinery had decided to install these valves on every emergency shutdown (ESD) valve to identify degradation by using partial stroke testing (PST) for these critical valves.

This entry describes how an installed Neles erosion/abrasion resistant ceramic valve solution has helped a customer improve FCC unit performance and profitability. In this particular case eroding 2″ to 10″ valves in a refinery’s fluid catalytic cracking (FCC) unit were causing problems that degraded both productivity and profitability. Neles application engineers analyzed the problem and provided a solution that quickly paid itself back many times over.

A catalyst, by definition, is a substance that enhances a chemical reaction. In the refining industry, catalysts are extensively used in many upgrading processes. One common upgrading process in refineries is the Fluid Catalytic Cracking unit (FCC) unit, which converts heavier distillation cuts into lighter, more profitable products, such as gasoline. This unit has many severe service valve applications that require special attention to design and material selection.
Insights
An emergency shutdown (ESD) valve is part of a safety instrumented system (SIS) and normally refers to all types of safety system valves. Much confusion still exists when it comes to what should be considered with these valves to make a plant safe.
