Abstract

Способ рекуперации этиленоксида (ЕО) из обогащенного абсорбента (FA), который включает обеспечение подачи FA, имеющего повышенную температуру, в десорбер ЕО, обеспечение подачи десорбирующего газа и контактирование при повышенной температуре с подачей FA, имеющей повышенную температуру, получение десорбированного обедненного абсорбента (LA) и газа, содержащего ЕО, и обеспечение одной или больше подач внешних потоков процесса в десорбер ЕО в месте выше подачи FA, имеющей повышенную температуру, и при более низкой температуре относительно подачи FA, имеющей повышенную температуру, таким образом, концентрируя ЕО в газе, содержащем ЕО, и (или) включает одну или больше ступеней удаления примесей в форме одного или больше боковых выпусков из десорбера ЕО или концентратора десорбера ЕО, и аппарат для этого способа.
