  • HF alkylation process with internal acid regeneration
    Patent number: 8501123
    Abstract: An improved process for removing polymeric by-product (ASO) from the HF alkylation acid in an HF alkylation unit used for the production of gasoline boiling range alkylate product by olefin/iso-paraffin alkylation, comprises fractionating a portion of the circulating HF alkylation acid inventory of the unit with a portion of hot alkylate product in a fractionation zone to from an overhead product comprising HF alkylation acid and water and a bottoms fraction comprising the polymeric by-product and alkylate. The bottoms fraction is sent to the isoparaffin stripper of the unit to remove trace HF alkylation acid as overhead and form a product stream of hot alkylate as a bottoms fraction.
    Type: Grant
    Filed: June 4, 2012
    Date of Patent: August 6, 2013
    Assignee: ExxonMobil Research and Engineering Company
    Inventors: D'Arcy H. J. Blais, Doug F. Bodeux, Steve L. Burgwin, Alexander D. Chan, Gary S. Locke, Jerry H. Squires, Sarah J. Virtue
