Abstract
This invention relates to a process for separating a heavy hydrocarbon stream to produce at least one permeate product stream and at least one retentate product stream. The process utilizes an ultrafiltration process to designed to maximize the quality of the permeate and retenate product streams as well as process embodiments which improve permeate production quantities as well as improve the quality of the product streams obtained by the separations process. In preferred embodiments, the process includes configuration and operational parameters to maximize permeate yield and selectivity.
