摘要：
The present invention is a method for operating a rapid cycling pressure swing adsorption (RCPSA) having a cycle time, T, to separate a feed gas into a non-adsorbed gas and tail gas. The method includes the steps of passing the feed gas having a purity of F % at high pressure into a first end of a bed which selectively adsorbs the tail gas and passes the product gas out a second end of the bed for a time, F. The product gas has a purity, P %, and a rate of recovery of R %. Then the bed is cocurrently depressurized for a time, t co , followed by countercurrently depressurizing the bed for a time, t CN . The bed is then purged for a time, t P , wherein desorbate (tail gas) is released at the first end of the bed at a pressure greater than 30 psig. Subsequently the bed is repressurized for a duration, t RP
摘要（中）：
本发明是用于操作具有循环时间T的快速循环变压吸附（RCPSA）的方法，以将进料气体分离成非吸附气体和尾气。 该方法包括以下步骤：将具有F％纯度的进料气体在高压下进入床的第一端，床的第一端选择性地吸附尾气并将产物气体从床的第二端排出一段时间。 产物气体的纯度为P％，回收率为R％。 然后将床并流减压一段时间，然后使床逆流减压一段时间。 然后将床清洗一段时间，其中在床的第一端以大于30psig的压力释放脱硫（尾气）。 随后将床重新加压一段时间，t
