ABSTRACT:
In a process for the treatment of heavy oil, in which a hydrocarbon diluent is added to the heavy oil stream, part of the diluent is substituted by an LPG liquid stream. The LPG stream is added to the heavy oil stream after removal of light components including methane and carbon dioxide to reduce the vapor pressure of the stream, producing a sales oil stream.
