  • Heat exchanger antifoulant
    Patent number: 4410419
    Abstract: Disclosed is a process for reducing the fouling in a heat exchanger in which a hydrocarbon stream is heated or cooled as it passes through the heat exchanger. From 1 to 500 parts per million of a dialkyl fatty-acid amide is added to the stream to reduce fouling.
    Type: Grant
    Filed: July 14, 1982
    Date of Patent: October 18, 1983
    Assignee: Chevron Research Company
    Inventor: Richard L. Ferm
  • Hydroxy-aluminum/lignin sulfonate compositions
    Patent number: 4394213
    Abstract: A composition comprising salts of lignin sulfonate and hydroxy-aluminum and water. The composition stabilizes soil formations from the effects of water and increases the water resistance of paper products.
    Type: Grant
    Filed: July 1, 1981
    Date of Patent: July 19, 1983
    Assignee: Chevron Research Company
    Inventor: Richard L. Ferm
  • Quick-setting bituminous emulsion compositions
    Patent number: 4351750
    Abstract: Quick setting, anionic bitumen emulsion compositions, suitable for road paving, recreational surfaces, etc., are formulated by emulsifying the bitumen in water with an ammonium or alkali metal salt of a hydrocarbon-substituted sulfuric, sulfonic, phosphoric or phosphonic acid emulsifier, mixing the emulsion with a fine aggregate and, prior to spreading the aggregate emulsion mixture, introducing an alkaline earth metal set initiator. The resulting composition rapidly breaks to a hard cohesive structure, so as to permit early use by traffic.
    Type: Grant
    Filed: July 28, 1980
    Date of Patent: September 28, 1982
    Assignee: Chevron Research Company
    Inventors: Richard L. Ferm, Chester C. Latif
  • Calcium polysulfide soil stabilization method and compositions
    Patent number: 4243563
    Abstract: Soil is stabilized and strengthened by application of solutions of calcium polysulfides. Compositions useful for soil stabilization comprise aqueous solutions of calcium polysulfide or aqueous mixtures of calcium polysulfides and dispersed organic polymers. Emulsifiers provide soil penetration.
