Abstract
The present disclosure provides a process and system for treating a feed diluent to produce a retentate product that is enriched in a heavy diluent component. The process includes: applying the feed diluent to a feed side of an organic solvent nanofiltration membrane; causing the light diluent component in the diluent to preferentially pass through the membrane in comparison to the light diluent component in the feed diluent; and producing the retentate product that is enriched in the heavy diluent component in comparison to the heavy diluent component in the feed diluent.
