Fractionator Bottoms Flow Control

Capacity, erosion resistance and performance are key.

The main fractionator column bottom to reactor flow control loop uses a control valve to recycle some of the bottom slurry back to the reactor for further processing. There is potential for the creation of extensive erosion in the control valve due to the presence of entrained catalyst in the flow stream.

Our valve solutions leverage Emerson's expertly designed control valve technologies designed specifically for erosive applications.

A Fisher™ V500 Eccentric Plug Valve is installed in many applications, but a Fisher severe service control valve is the most rugged solution. Both the Fisher V500 rotary globe control valve and the Fisher 461 Increased Outlet Angle SweepFlo Valve are available with special upgraded trim offerings suitable for erosive fractionator bottoms, heavy ends and catalyst flows.
