Abstract

Изобретение включает способ удаления из газовых смесей сероводорода. Способ включает использование смеси из растворителя для физического абсорбирования и ионной жидкости. Смесь обеспечивает получение улучшенного абсорбирования сероводорода в сопоставлении с указанными растворителями для физического абсорбирования при отсутствии ионной жидкости при низких парциальных давлениях сероводорода. Для регенерирования смеси используют цикл регенерирования, включающий добавление растворителя, такого как вода.
