Abstract

Способ удаления газа, способного захватывать амин, из потока сырьевого газа, используя аминосодержащий растворитель, включает (а) контактирование потока сырьевого газа с обедненным аминосодержащим растворителем для получения обогащенного аминосодержащего растворителя, в котором термически стабильные соли присутствуют в обогащенном аминосодержащем растворителе; (b) десорбирование газа, способного захватывать амин из обогащенного аминосодержащего растворителя с образованием обедненного аминосодержащего растворителя и потока дистиллятной флегмы; (с) периодически контактирование по меньшей мере части одного или обоих обедненного аминосодержащего растворителя и обогащенного аминосодержащего растворителя с анионообменной смолой с образованием первой термически стабильной соли обедненного аминосодержащего растворителя; (d) периодически регенерацию анионообменной смолы, в которой в течение регенерации анионообменной смолы по меньшей мере часть потока флегмы используют для промывания аминосодержащего растворителя от анионообменной смолы с образованием второй термически стабильной соли обедненного аминосодержащего растворителя; и (е) рециркуляцию по меньшей мере части первой и второй термически стабильной соли обедненного аминосодержащего растворителя для использования в захвате газа, способного захватывать амин из сырьевого газа.
