ABSTRACT:
A method of converting an HF alkylation process into a solid catalyst alkylation process is disclosed. In this method, an HF alkylation unit having an HF stripper downstream of the HF alkylation reactor is modified to a benzene rectifier. By modifying the HF stripper, this invention not only makes use of the existing HF stripper but also allows the entire downstream product recovery section, which comprises four fractionation columns, to be used in the modified process with only relatively minor modifications. Thus this invention maximizes the use of existing equipment and minimizes the investment necessary to eliminate the use of HF in detergent alkylation.
