APPARATUS AND PROCESS FOR CATALYTIC CONVERSION OF OLEFINS TO HEAVIER HYDROCARBONS

摘要

A control system is provided for an olefins upgrading plant wherein catalytic reactor effluent is separated to recover heavy, intermediate and light hydrocarbon streams. An improved liquid recycle system includes a level control technique for diverting a portion of a separator overhead vapor stream. Recycle flow rate may be determined by reactor temperature differential in a series of adiabatic catalytic reactors.
