ABSTRACT:
An improved system for performing an alkylation process and a method for handling liquid catalyst in an alkylation process. This improvement involves a method and apparatus by which liquid alkylation catalyst contained in alkylation process equipment can be safely stored and isolated from the external environment. Additionally, the apparatus improvement will allow for an improved method for controlling the circulation of liquid alkylation catalyst by providing means for quickly stopping the circulation of alkylation catalyst. The apparatus improvement includes a baffle contained within a vessel which is attached to the bottom of the vessel and extends upwardly into the vessel. The baffle is designed to allow for the liquid flow between the inside of the vessel and the inside of the baffle and it allows for the venting into a vapor space from the top of the baffle. Within the baffle is standpipe which provides for fluid flow from within the baffle to a region outside the vessel.
