  • Patent number: 8071044
    Abstract: In an isomerization process where the isomerization effluent (108) is fractionated in a deisohexanizer (116) to provide an overhead (118) containing dimethylbutanes and a higher boiling fraction (122) containing normal hexane, the higher boiling is contacted with a selectively permeable membrane (124) to provide a retentate containing methylcyclopentane (128). If desired, the normal hexane-containing permeate can be recycled for isomerization. The preferred membranes are sieving membranes having a C6 Permeate Flow Index of at least 0.01 and a C6 Permeate Flow Ratio of at least 1.25:1.

  • Patent number: 8062613
    Abstract: An apparatus and process for isomerizing a hydrocarbon stream rich in a C4 hydrocarbon and/or at least one of a C5 and C6 hydrocarbon which includes a first drier and a second drier; and a reaction zone communicating with at least the first drier. The first drier operates at a first condition to dry the reactant and the second drier operates at a second condition during regeneration. The used regenerant remaining in the second drier after regeneration can (1) pass through a vent-to-flare assembly in a batch-wise manner; (2) pass through a downflow-depressure-to-low-pressure-device assembly in a batch-wise manner; (3) pass through a cross-over piping purge assembly to minimize upsets in the reaction and fractionation zones when the second drier is placed back in operation; or any combination of (1) (2) and/or (3) to minimize upsets in the reaction and fractionation zones when the second drier is placed back in operation.

  • Patent number: 8058492
    Abstract: A process for controlling the concurrent production of both diesel range hydrocarbons and aviation range hydrocarbons from renewable feedstocks such as plant oils and animal oils. The process involves determining the required specification of the desired products and the desired relative yields of the product that still meet the required specifications. The necessary isomerization and selective hydrocracking zone conditions are determined in order to create a mixture of paraffins which meet the required product specifications and yields. The necessary fractionation zone conditions are determined to separate the desired products.
