    摘要： Acidic gases are substantially removed from a normally gaseous mixture by a process comprising contacting the normally gaseous mixture with an amine-solvent liquid absorbent comprising (i) an amine comprised of at least about 50 mol % of a sterically hindered amine, and (ii) a solvent for said amine mixture which is also a physical absorbent for said acidic gases. The liquid absorbent may also include up to about 35 weight percent water.

    摘要： Carbon dioxide containing acidic gases are substantially removed from a normally gaseous mixture by a process comprising contacting the normally gaseous mixture with an aqueous amine solution, wherein the amine consists of at least about 50 mol % of a sterically hindered amino alcohol and at least about 10 mol % of a tertiary amino alcohol, wherein said sterically hindered amino alcohol contains at least one secondary amino group which is part of a ring and is attached to either a secondary or tertiary carbon atom or a primary amino group attached to a tertiary carbon atom. The coaction of the sterically hindered amino alcohol and the tertiary amino alcohol provide an increase in the amount of carbon dioxide containing acidic gases absorbed compared to the use of the sterically hindered amines alone and lowers the heat of reaction.

    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.
