Abstract

Абсорбент для селективного удаления сероводорода над диоксидом углерода из потока текучей среды, при этом абсорбент содержит водный раствор, содержащий амин формулы (I) и/или амин формулы (II)где U-V-W представляет собой CH-O-CHR, N-CO-CHRили N-CO-NR; U'-V'-W' представляет собой C-O-CR; Rпредставляет собой независимо C-C-алкил; Rвыбран из водорода и C-C-алкила; Rнезависимо выбран из водорода и C-C-алкила; Rнезависимо выбран из водорода и C-C-алкила; Rвыбран из водорода, C-C-алкила, (C-C-алкокси)-C-C-алкила и гидрокси-C-C-алкила; и х представляет собой целое число от 1 до 10. Указанный абсорбент имеет пониженную склонность к фазовому разделению при температурах в обычном диапазоне температур регенерации для водных аминных смесей и низкую летучесть в водных растворителях.
