  • Diluent substitution apparatus
    Patent number: 4994149
    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.
    Type: Grant
    Filed: November 3, 1989
    Date of Patent: February 19, 1991

  • Diluent distillation process and apparatus
    Patent number: 4661242
    Abstract: An improvement in a process for the treatment of heavy oil in which a hydrocarbon diluent is subjected to distillation prior to its addition to a heavy oil production stream, to remove at least some of the light components in the diluent that would otherwise vaporize in the treatment process. A distillation unit for use in the process is also disclosed.
