Abstract:
A system for alkylating hydrocarbons which includes an improved method of safely handling alkylation catalyst is disclosed. The process includes passing the alkylation catalyst from a settler vessel to a catalyst receiving vessel, via a catalyst cooler, for containment therein in the presence of a condensible gas. Also disclosed is a method for controlling the pressure in the catalyst receiving vessel by controlling the rate of removal of vapors.
