Abstract

В способе отделения метана от смеси природного газа применяют адсорбцию с переменным давлением в одном или более емкостях. Каждая емкость имеет адсорбентный материал, обладающий кинетической селективностью для загрязнений, относительно метана, свыше 5. Загрязнения в смеси природного газа становятся газами, кинетически адсорбированными внутри адсорбентного материала. Емкость располагают под давление, чтобы вызвать адсорбцию загрязнений в поверхностях и микропорах адсорбентного материала. Способ включает в себя этапы выведения продуктового потока, содержащего по меньшей мере 95% метана по объему, из первого выпуска для газа в емкости и десорбции загрязняющих газов из адсорбентного материала понижением давления внутри емкости. Этап десорбции выполняют без подведения тепла к емкости, тем самым выводя поток отходящего газа, содержащего по меньшей мере 95% загрязняющих газов по объему. Также представлена усовершенствованная фракционирующая емкость, имеющая как основные, так и второстепенные проточные каналы.
