Improve coker efficiency with reliable valve automation
The case history discusses conditions occurring in delayed coker operations at two refineries in Louisiana, the impacts on valve performance, and a solution that offers extended life, better reliability and other benefits.
A refinerys delayed coker unit (Fig. 1) operates under what are perhaps the harshest conditions of any process in the plant. Equipment with moving parts, notably valves and the actuators that operate them (Fig. 2), are especially vulnerable to these severities. The following case history discusses conditions occurring in delayed coker operations at two refineries in Louisiana, US; the impacts on valve performance; and a solution that provides extended life, increased reliability and other benefits at the facilities.
