最近,变压吸附技术用来从双组分或多组分原料气中生产多种高纯度、高回收率产品气,这些过程还用来改变原料气混合物的组成.阐述了这些新过程的一个实例,并对其性能作了报道.这些过程所采用的工业用吸附剂都出自总吸附剂的一个大族,如沸石、活性炭、硅胶、铝胶等,其中大部分在性能方面都是相当混杂的。这就使得这些过程的演绎设计异常困难,需要实验过程运行性能数据。还讨论了与该课题有关的几个基本问题。图3表2.
More recently, PSA technology has been used to produce a wide range of high-purity, high-recovery product gases from bi-component or multicomponent feed gases and these processes have also been used to alter the composition of the feed gas mixture. One of these new processes Examples and reports on their properties.The industrial adsorbents used in these processes are all from a large family of total adsorbents such as zeolites, activated carbons, silica gels, aluminum glues and the like, most of which are quite mixed in terms of performance . This makes the interpretation of these processes is extremely difficult to design, the experimental process performance data. Several basic issues related to this topic were also discussed.
