摘要： An air separation method in which a pre-purification unit 16 is provided with three or more beds which are subjected to a pressure swing adsorption process. Each of the beds is subjected to feed, pressurisation, purge and repressurization stages. The purge stages are conducted with a waste stream from the air separation unit and the duration of the purge stage is equal to the total time of the cycle divided by the number of beds, and thus the waste stream is used continuously to purge the beds.
摘要翻译：一种空气分离方法，其中预净化单元16设置有三个或更多个经受变压吸附处理的床。每个床都经受进料，加压，吹扫和再加压阶段。吹扫阶段利用来自空气分离单元的废物流进行，并且吹扫阶段的持续时间等于循环的总时间除以床的数量，并且因此废物流被连续地用于吹扫床。

摘要： A PSA process for the pre-purification of air to remove water vapour and carbon dioxide prior to introduction into an air separation unit, comprises in cyclical sequence, feeding air into the bottom of bed A containing adsorbent effective to remove water vapour and carbon dioxide from the air and withdrawing purified air from the top of bed A (valves 1 and 3 open) while first regenerating bed B first by venting it to atmosphere (valves 8 and 9 open), second evacuating it (valves 8 and 10 open), and third purging it with a (nitrogen) stream from the air separation unit while continuing the evacuation (valves 6, 8 and 10 open); at the end of the purge step, passing purified air from the top of bed A into the top of bed B (valves 1, 3 and 4 open); using bed B for production of pure air (valves 2 and 4 open) while subjecting bed A to first a vent to atmosphere (valves 7 and 9 open), second evacuation (valves 7 and 10 open), and third a combined purge/evacuation (valves 5, 7 and 10 open); and then passing purified air from the top of bed B into the top of Bed A (valves 2, 3 and 4 open). The three-step regeneration sequence described above makes it possible to reduce the consumption of purge gas and reduce bed size in comparison with comparable processes known from the prior art.

摘要： An improved pressure swing adsorption process is disclosed for the recovery of high-purity primary and secondary components from a multicomponent gas mixture. The process utilizes a first group of adsorbent beds selective for the secondary component and a second group of adsorbent beds selective for retention of tertiary impurities in the mixture. The gas mixture is passed through a first and second bed in series, very high purity primary component product is discharged from the second bed, and high purity secondary component product is recovered by desorption from the first bed. A low-pressure purge of the first bed with high-purity secondary component product is utilized to minimize compression power and improve purity of the secondary product component. Several novel pressure equalization steps improve primary product recovery and reduce power consumption. Further increased product recovery is realized by recycling depressurization and purge streams from the first bed. The process can be used to recover high-purity hydrogen and carbon dioxide from a gas mixture containing these components along with minor amounts of methane, carbon monoxide, and nitrogen.

摘要： A process for separating nitrogen gas higher in purity than conventional products from a gas mixture predominantly composed of nitrogen gas and oxygen gas by the pressure swing adsorption system using carbon molecular sieve as adsorbent is characterized by the manner of communicating an adsorber after adsorption step with an adsorber after regeneration step for gas transfer from the former adsorber to the latter, the operation of discontinuing the gas transfer before establishment of pressure equalization, and the regeneration promotion by causing back flow of part of product gas.
The process can separate 99.99% pure nitrogen gas, which is never obtainable in the prior pressure swing adsorption processes, from air as raw material in an economic manner.
