Publication number: 20230226483Abstract: Capture of hydrogen sulfide from a gas mixture may be accomplished using an aqueous solution comprising an amine. Certain sterically hindered amines may selectively form a reaction product with hydrogen sulfide under kinetically controlled contacting conditions and afford a light phase and a heavy phase above a critical solution temperature, wherein the hydrogen sulfide may be present in either phase. Upon separation of the light phase from the heavy phase, processing of one of the phases may take place to remove hydrogen sulfide therefrom. Recycling of the amine to an absorber tower may then take place to promote capture of additional hydrogen sulfide.Type: ApplicationFiled: July 6, 2021Publication date: July 20, 2023Inventors: Carla S. Pereira, Jenny P. Seagraves, P. Scott Northrop, Michael Siskin, Thomas Ingram, Gerald Vorberg, Martin Ernst, Georg K. Sieder
