  • Removal of hydrogen sulfide from elemental sulfur by a countercurrent wet steam process
    Patent number: 4537605
    Abstract: Hydrogen sulfide is removed from molten petroleum byproduct sulfur to levels below 1 ppm by weight by contacting the sulfur in countercurrent with wet steam. Preferably, the wet steam is sour water steam and the contacting is carried out in a packed bed column.

  • Apparatus and method for determining the vapor pressure of heavy hydrocarbon mixtures
    Patent number: 4395903
    Abstract: A vapor pressure method and apparatus for accurately determining the vapor pressure of heavy crude oil and residual fractions is disclosed. A test sample of the crude or residuum is held in a constant temperature vessel from which vapors are continuously withdrawn and recycled into the crude or residuum until equilibrium is established. Once equilibrium is established a specimen of the vapors is extracted from the recycle line and analyzed by a gas chromatograph. Vapor pressure is calculated from the chromatographic analysis by known procedures.
