  • Processes using solid perm-selective membranes in multiple groups for simultaneous recovery of specified products from a fluid mixture
    Patent number: 6830691
    Abstract: Economical processes of the present invention are for separation of fluid mixtures to recover desired products using apparatus comprising a plurality of membrane modules disposed in a first product group, a second product group, and optionally one or more intermediate group. Advantageously integrated processes of the invention with the membrane modules in multiple groups are employed for simultaneous recovery of a very pure permeate product and a desired non-permeate product from a mixture containing organic compounds.
    Type: Grant
    Filed: June 27, 2002
    Date of Patent: December 14, 2004
    Assignee: BP Corporation North America Inc.

  • Co-alkylation for gasoline RVP reduction
    Patent number: 6429349
    Abstract: Methods and apparatus that are used in an alkylation reactor system for adding low purity isopentane to alkylation reactor feed to block formation of isopentane, resulting in high incremental isopentane conversion and minimal octane and C5+ yield loss, and low acid consumption from C6+ isoparaffins with superior yields.
