  • Process for the separation of crude oil emulsions of the water-in-oil type
    Patent number: 5039450
    Abstract: A process for the separation of crude oil emulsions of the water-in-oil typeIn the novel process addition products made from certain ethylene oxide/propylene oxide block polymers and certain polyglycidyl ethers of phenol/formaldehyde condensation products are added to the crude oil emulsions.
    Type: Grant
    Filed: March 16, 1989
    Date of Patent: August 13, 1991
    Assignee: Hoechst Aktiengesellschaft
    Inventors: Rainer Kupfer, Willibald Bose, Martin Hille, Roland Bohm, Friedrich Staiss
  • Branched polyoxyalkylene copolyesters, a process for their preparation, and their use
    Patent number: 4885110
    Abstract: Branched polyoxyalkylene copolyesters are described which are prepared by esterifying an oxyalkylated primary fatty amine and an at least trihydric oxyalkylated alkanol or an oxyalkylated polyamine using a dicarboxylic acid or a dicarboxylic anhydride with polycondensation. The novel branched polyoxyalkylene copolyesters are used as demulsifiers for breaking crude oil emulsions.
    Type: Grant
    Filed: November 12, 1987
    Date of Patent: December 5, 1989
    Assignee: Hoechst Aktiengesellschaft
    Inventors: Willibald Bose, Manfred Hofinger, Martin Hille, Roland Bohm, Friedrich Staiss
  • Oxalkylated polyester-amines, a process for their preparation and their use
    Patent number: 4734523
    Abstract: Oxalkylated polyester-amines which are prepared by esterifying, with polycondensation, an oxalkylated primary fatty amine with a diol and with a dicarboxylic acid, are described. These polyester-amines are used as demulsifiers for breaking crude oil emulsions.
    Type: Grant
    Filed: July 23, 1986
    Date of Patent: March 29, 1988
    Assignee: Hoechst Aktiengesellschaft
    Inventors: Manfred Hofinger, Willibald Bose, Martin Hille, Roland Bohm, Friedrich Staiss
  • Quaternary oxalkylated polycondensates
    Patent number: 4730079
    Abstract: Quaternary oxalkylated polycondensates are described; these are prepared by esterifying, with polycondensation, an oxalkylated primary fatty amine with a diol and with a dicarboxylic acid, and oxalkylating the resulting reaction product in the presence of a carboxylic acid. These polycondensates are used as demulsifiers for breaking crude oil emulsion and as corrosion inhibitors in plants for the recovery and treatment of natural gas and crude oil.
