    • A process for recovering a hydrocarbon (I) from a gas stream contg. (I) and small amounts of oxygen is carried out by a pressure change adsorption process in a number of adsorbers operating cyclically. During an adsorption phase at elevated press., a selective adsorption of (I) occurs, during the adsorption phase and during at least one equilibrating phase, a gas stream is drawn off the outlet end of an adsorber, which is depleted in (I) to be recovered, during at least one subsequent counter flow depressurization from the inlet end of the adsorber, a desorbate stream enriched in (I) is drawn off, and after the desorption, the adsorber undergoes a pressure building phase during which it is returned to adsorption press. with a gas low in oxygen.
    • 从气流中回收烃(I)的方法, (I)和少量氧气通过循环操作的多个吸附器中的压力变化吸附过程进行。 在升高的压力下的吸附阶段期间,在吸附阶段期间和在至少一个平衡阶段期间,(I)的选择性吸附发生在吸附器的出口端,其被耗尽(I) 在从吸附器的入口端进行的至少一个随后的逆流减压过程中,回收富含(I)的解吸附物流,并且在解吸后,吸附器进行压力建立阶段,在此阶段将其返回 吸附压力机。 气体氧气低。
