Abstract
The acid catalyzed—effluent refrigerated alkylation of hydrocarbons in a shell and bare tube type alkylation reactor is improved by providing the bare tubes with internal inserts capable of increasing turbulence and mixing of refrigerant within the tubes whereby heat transfer in the process is enhanced.
