Aromatic hydrocarbon separation via solvent extraction
Patent
·
OSTI ID:7287956
A solvent extraction process for separating polar hydrocarbons from non-polar hydrocarbons is claimed. The solvent-rich extract phase is introduced into a stripping column, the bottoms from which, a polar hydrocarbon-containing, solvent-rich stream, is introduced into an upper portion of a solvent recovery column. A vaporous stripping medium is introduced into a lower portion of the solvent recovery column. Polar hydrocarbons in concentrated form are recovered as an overhead stream. A solvent-rich stream, virtually free from hydrocarbons, is withdrawn as a bottoms product and recycled to the extraction zone, while a hydrocarbon-containing side-cut solvent-rich phase is withdrawn and introduced into the stripping column with the extract phase.
