ABSTRACT:
The present invention provides an apparatus for preparing and treating a heavy oil extraction solvent. A solvent fraction is separated from a crude oil and combined with a slip stream of rerun solvent taken from an extraction process solvent recycle system. The solvent fraction and rerun solvent are fractionated to provide a purified extraction solvent. The purified extraction solvent is then utilized in the heavy oil extraction process.
