CIRCOR | TAPCO-ENPRO Isolation Valve

In this video animation, learn how TAPCO-ENPRO's Isolation Valve provides a safer environment when isolating the reactor from the fractionator resulting in safer FCCU operations.


FCCU Reactor - Fractionator Isolation Valve

A Fluid Catalytic Cracking Unit (FCCU) is expected to operate without interruption for 3 to 6 years. Maintenance requirements include isolating the reactor from the fractionator by placing a physical blind in the reactor overhead line. The manual insertion and removal of the blind flange is one of the most threatening operations in the refinery. There is a need for a safe operator environment for isolation of a hazardous process by eliminating personnel from the operation and emissions of hydrocarbons to the atmosphere.

TapcoEnpro has met the challenge to provide a protected environment during the manual installation of the physical blind by providing automated isolation of the reactor from the fractionator resulting in safer FCCU unit operations.
