  • Process for the removal of heat stable salts from acid gas absorbents
    Patent number: 10118123
    Abstract: A process for the regeneration of an acid gas absorbent comprising an amine and heat stable salts by phase separation, comprising a) mixing the acid gas absorbent with an alkaline solution, to form a mixture with a pH above the pH equivalence point of the amine; b) cooling the mixture to a temperature below 500 C; c) separating the mixture into a regenerated acid gas absorbent and a waste stream; d) collecting the regenerated acid gas absorbent separate from the waste stream.
    Type: Grant
    Filed: March 17, 2011
    Date of Patent: November 6, 2018
    Assignee: SHELL OIL COMPANY
