摘要： Gas separation by pressure swing adsorption (PSA) and vacuum pressure swing adsorption (VPSA), to obtain a purified product gas of the less strongly adsorbed fraction of the feed gas mixture, is performed with an apparatus having a plurality of adsorbers. The adsorbers cooperate with first and second valve means in a rotary PSA module, with the PSA cycle characterized by multiple intermediate pressure levels between the higher and lower pressures of the PSA cycle. Gas flows enter or exit the PSA module at the intermediate pressure levels as well as the higher and lower pressure levels, under substantially steady conditions of flow and pressure. The PSA module comprises a rotor containing laminated sheet adsorbers and rotating within a stator, with ported valve faces between the rotor and stator to control the timing of the flows entering or exiting the adsorbers in the rotor. Feed gas is compressed prior to entry to the first valve means. Exhaust is passed either directly or through a vacuum pump to the atmosphere.
摘要翻译：用具有多个吸附器的装置进行通过变压吸附（PSA）和真空变压吸附（VPSA）的气体分离，以获得进料气体混合物的较弱吸附级分的纯化产物气体。吸附器在旋转PSA模块中与第一和第二阀装置配合，PSA循环的特征在于PSA循环的较高和较低压力之间的多个中间压力水平。在基本上稳定的流量和压力条件下，气体流在中间压力水平以及较高和较低压力水平下进入或离开PSA模块。 PSA模块包括含有层压片吸附器并在定子内旋转的转子，其中转子和定子之间具有带孔的阀面，以控制进入或离开转子中的吸附器的流动时间。进料气体在进入第一阀装置之前被压缩。排气直接或通过真空泵通入大气。
