    摘要: In one embodiment, the invention is related to a process for desalting crude oil that requires less wash water than conventional desalting methods. In the preferred embodiment of the invention, a chemical demulsifier formulation comprising an emulsion-breaking chemical and a solvent carrier is added to the crude oil. Wash water is then added to the crude oil until the volume of water in the oil ranges from about 0.1 to about 3 vol. %. Subsequently, the mixture of crude oil, wash water, and chemical demulsifier formulation is subjected to opposed-flow mixing. Chemical emulsion-breakers useful in the invention have a hydrophobic tail group and a hydrophilic head group. Preferably, the emulsion breaker has the formula: x ranges from 1 to 5, y ranges from 0 to 2, and R is an alkyl group having 4-9 carbon atoms, and n ranges from 3 to 9.

    摘要: The present invention relates to an alkaline promoter system comprising specific mixtures of nonsterically hindered amino compounds and sterically hindered amino acids and their use in acid gas scrubbing processes. The preferred promoter system comprises a mixture of (i) diethanol amine or 1,6-hexanediamine and (ii) N-secondary butyl glycine or pipecolinic acid.
