Fractionator Bottoms Flow Control

Capacity and performance are key.

A fractionator bottom to reactor flow control loop uses a control valve to recycle some of the bottom slurry back to the reactor for further processing. The potential for the creation of a great deal of erosion in the control valve exists due to entrained catalyst.

Our solution leverages Emerson's expertly designed technologies.

An Emerson 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 Sweep-Flo Valve are available with special upgraded trim offerings suitable for erosive catalytic bottoms, heavy ends and erosive catalyst flows. Steel, SST or chrome moly bodies which are designed specifically for harsh conditions will increase your technology’s life and Emerson Rosemount™ 3051 Differential Pressure Flow Transmitters assist in measuring flow with several different primary elements.
