Patent number: 11819798Abstract: A scrubbing solution for removing contaminants, including particularly hydrogen sulfide, from a fluid. The scrubbing solution includes at least one scrubbing reagent which has a primary or secondary amine and an acid, which may be phosphoric acid. The fluid being scrubbed is passed through the scrubbing solution. The contaminants react with the scrubbing reagent securing them in the scrubbing solution. The fluid being scrubbed and the scrubbing solution are then separated. The scrubbing solution is heated and, if the scrubbing solution is under pressure, the pressure is reduced. The acid facilitates thorough removal of the contaminants, and especially the hydrogen sulfide, from the scrubbing solution. The scrubbing solution is then ready for reuse. Because the scrubbing solution is rendered substantially free of hydrogen sulfides, it can absorb other sulfide contaminants that might not otherwise be absorbed.Type: GrantFiled: January 24, 2022Date of Patent: November 21, 2023Assignee: INEOS AMERICAS, LLCInventors: Eric Matthew Teletzke, Flavia Mariana Dos Santos Bates, Brett Christopher Roberts, Erik John Stewart, Kathleen Yvonne Turk

Publication number: 20230106908Abstract: A method and apparatus for continuously treating acid gases including recovering absorbent chemicals by introducing streams leaving a regenerator and/or leaving an absorber into a static mixing zone wherein supplemental washing water is added to recover absorbent chemicals. Improvements to the prior art methods are provided where one or more absorbent chemical recovery units are included to increase the amount of recovered absorbent chemicals exiting the regenerator and/or exiting the absorber are increased and/or maximized. Absorbent chemical recovery units can include mixing units where liquid is added to the stream of sour gas and absorbent chemical to mix with and absorb the absorbent chemical from the stream.Type: ApplicationFiled: September 2, 2022Publication date: April 6, 2023Applicant: Ineos Americas, LLCInventors: Ulises I. Cruz, Erik J. Stewart, Rodrigo Zamora
