FCCU Fractionator Isolation Valves
See how the TapcoEnpro Isolation Valve provides a safer environment when isolating the reactor from the fractionator resulting in reliable FCC operations and beneficial cost saving during turnarounds.
An 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.
- Smallest Dimensional Footprint
- Top Entry In-Line Serviceable
- Lowest Steam Consumption
- Safer Valve Design

Our Solutions
- Gate is in a safe down-seated position while open and regardless of upset conditions or equipment failure, the gate remains static and will not close
- Ultra-low steam consumption
Industry Challenges to Solve
- Volatile and Hazardous emissions released to atmosphere during blind installation
- Hazardous work environment for operators installing the fractionator isolation blind
- Time consuming blind installation leads to costly added time in unit outages to shutdown and start-up
Industry Challenges Solved
- Provides greater opportunity for safe isolation of vessels
- 100% process isolation with Double Block and Purge technology
