摘要： In a cyclic adsorptive gas purification process, an impurity laden adsorbent is regenerated by exposing it first to an unheated gas for a pre-determined time period to desorb at least some of the impurity, followed by heating the adsorbent using a flowing stream of a heated gas to desorb the remaining impurities over another pre-determined time period, further followed by cooling of the adsorbent using a flowing stream of gas for yet another pre-determined time period to make it ready for repeating the adsorptive cycle. Introducing an unheated purge stream reduces the energy requirements for the regeneration step compared to a traditional TSA process.

摘要： An air compression system and method for an air separation plant in which air is compressed in a series of compression stages and a temperature swing adsorption unit adsorbs water vapor and carbon dioxide. The temperature swing adsorption unit is situated at a location of the compression stages such that air pressure upon entry into the adsorbent beds is between about 400 psia and about 600 psia. Each of the adsorbent beds of the unit have a minimum transverse cross-sectional flow area that will set the air velocity of the air to a level below that at which adsorbent bed fluidization would occur. Such operation allows fabrication costs of the adsorbent beds to be reduced because less adsorbent and smaller adsorbent beds are required while power consumption will be at a minimum.

摘要翻译： 一种空气分离装置的空气压缩系统和方法，其中空气在一系列压缩级中被压缩，并且变温吸附单元吸附水蒸气和二氧化碳。 变温吸附单元位于压缩阶段的位置，使得进入吸附剂床的空气压力在约400psia至约600psia之间。 单元的每个吸附剂床具有最小横截面流动面积，其将空气的空气速度设定到低于吸附剂床流化的水平。 这种操作允许减少吸附剂床的制造成本，因为需要较少的吸附剂和较小的吸附剂床，同时功耗将降至最低。
