Abstract

Способ удаления COиз потоков природного газа на основе циклической адсорбции при переменном давлении с помощью комбинации селективного адсорбентного материала, содержащего эффективное количество неадсорбирующего наполнителя, конструкции адсорбентного контактора и схемы адсорбционного цикла. Удаление загрязняющих примесей из газовых потоков, предпочтительно потоков природного газа, с использованием короткоцикловых циклических адсорбционных процессов, таких как короткоцикловая адсорбция при переменном давлении (RC-PSA). Разделение при высоком давлении с высокой степенью извлечения продукта и/или высокой чистотой продукта обеспечивается комбинацией рациональных выборов адсорбентного материала, газотвердофазного контактора, конфигурации системы и схемы цикла. Например, схемы циклов, которые включают стадии продувки и ступенчатого выдувания, а также включение мезопористого наполнителя в адсорбентный материал, значительно повышают степень извлечения продукта (например, метана). RC-PSA-продукт с содержанием менее 10 млнHS может быть получен из сырьевого потока природного газа, который содержат менее 1 мол.% HS.
