  • Process for the separation of multicomponent mixtures using a prefractionation/main column arrangement
    Patent number: 11612829
    Abstract: This invention relates to a method of separating a multiproduct mixture using a prefractionation/main column arrangement to efficiently separate the multiproduct mixture into the desired individual products. One advantage of the invention is that it can be used to debottleneck an existing series of distillation columns, permitting a capacity expansion to take place without requiring the installation of an entire new train of distillation columns.

  • Energy efficient methods for isomerization of a C5-C6 fraction with dividing wall fractional distillation
    Patent number: 10118875
    Abstract: This invention relates to a method of separating an isomerization zone effluent mixture comprising between 5 and 7 carbon atoms into high octane isomerate product streams and low octane streams which may be recycled to the isomerization zone. The separation process makes use of a dividing wall column to efficiently perform the separation of isopentane and high octane multibranched paraffins from low octane straight chain and single branched paraffins.
