Abstract

Способ удаления кислых газов из потока текучей среды, причем поток текучей среды вступает в контакт с абсорбентом, с получением обработанного потока текучей среды и загруженного абсорбента, при этом абсорбент содержит разбавитель и соединение общей формулы (I)причем R1 выбран из C1-C8-алкила и C2-C8-гидроксиалкила; R2 выбран из водорода и C1-C8-алкила; R3 выбран из водорода и C1-C8-алкила; R4 выбран из водорода и C1-C8-алкила; R5 означает C1-C8-алкил; при условии выполнения по меньшей мере одного из следующих условий (i) и (ii): (i) R5 означает C3-C8-алкил, связанный с атомом азота через вторичный или третичный атом углерода; (ii) когда R4 означает водород, R3 означает C1-C8-алкил; или когда R4 означает C1-C8-алкил, по меньшей мере один из R2 и R3 означает C1-C8-алкил; и n означает целое число от 0 до 6. Кроме того, изобретение касается абсорбента для абсорбции кислых газов из потока текучей среды, содержащий разбавитель и соединение общей формулы (I), как определено выше, а также применения соединения общей формулы (I), как определено выше, для удаления кислых газов из потока текучей среды. Абсорбенты пригодны для селективного удаления сероводорода из потоков текучей среды и обладают высокой способностью к улавливанию кислых газов, высокой стабильностью и низкой летучестью.
