  • Process for treating crude oil using hydrogen in a special unit
    Patent number: 7001502
    Abstract: A process is provided for treating crude oil to visbreak and/or upgrade such oil using hydrogen gas. The process includes the steps of introducing hydrogen into a heated stream of crude oil or partially upgraded crude oil and mixing such introduced hydrogen with the oil to achieve intimate dispersion of hydrogen to enhance thereby visbreaking and/or upgrading.
    Type: Grant
    Filed: September 29, 1999
    Date of Patent: February 21, 2006

  • Jet pump treatment of heavy oil production sand
    Patent number: 6527960
    Abstract: A process for separating oily films from sand particles carried in a solvent free water stream includes the use of a jet pump scrubber in a density classification tank to treat such oily coated particles at controlled operating temperatures above 65° C. whereby, at such controlled temperature, enhanced cavitation in the jet pump separates the oily film from the sand particles to form slop oil, the tank providing for recirculation of the particles through the jet pump before discharge.

  • Jet pump treatment of heavy oil production sand
    Patent number: 6074549
    Abstract: In a process for separating oily films from sand particles carried in a sent free water stream, the use of a jet pump scrubber in a density classification tank to treat such oily coated particles at controlled operating temperatures above 65.degree. C. whereby at such controlled temperature enhanced cavitation in said jet pump separates said oily film from said sand particles to form slop oil, said tank providing for recirculation of sand particles through said jet pump before discharge.
