摘要： Die Trennung von Gasgemischen mit Vakuum Swing Adsorption in einem Zwei-Adsorber-System mit Gewinnung der weniger stark adsorbierbaren Phase und Desorption des adsorbierten Gasanteils bei Unterdruck in zwei, mit selektiv adsorbierendem Adsorptionsmittel gefüllten Adsorbern erfolgt im wesentlichen so, daß zwei Adsorber wechselseitig betrieben werden und daß zu keiner Zeit des Trennprozesses die Zufuhr des Rohgases und ebenso die Desorption des adsorbierten Gasanteils durch eine Vakuumpumpe unterbunden wird, wobei Adsorber A nach Erreichen seines maximalen Adsorptionsdruckes an dessen oberen Ende im Gleichstrom entspannt wird, gleichzeitig am unteren Ende des Adsorbers A die Vakuumpumpe angeschlossen bleibt, und gleichzeitig Adsorber B nach Ende seines Evakuierungsschrittes mit Entspannungsgas aus Adsorber A am oberen Adsorberende und zusätzlich am unteren Ende mit dem zu trennenden Rohgas teilweise aufgedrückt wird und dadurch das Rohgas bei abnehmendem Unterdruck getrennt wird.

摘要： The present invention is a process for separating and recovering a component from a multi-component feed gas mixture. The feed gas mixture is initially separated in a membrane separation unit or units to produce a gas stream concentrated in the desired component. The concentrated gas stream is subsequently further separated in an adsorption unit having an adsorbent which selectively adsorbs non-desired gaseous components thereby producing a purified product stream. The non-desired gaseous components are subsequently desorbed and a purge stream from the adsorption unit containing the desorbed non-desired gaseous components along with a portion of the desired components is recycled to the feed gas mixture.

摘要： A process is described for separating gas mixtures containing a primary gaseous component and a secondary gaseous component by selective adsorption of the secondary gaseous component in an adsorptive process including the steps of adsorption in at least one adsorbent bed, rinsing said bed with secondary component, depressurizing and evacuating said bed and repressurizing said bed with primary gaseous component. A key aspect of the process is the utilization of an adsorbent having a selectivity(S) greater than 20 for the gas mixture being resolved at the entire pressure and temperature ranges that the adsorbent in the bed undergoes during separation. The process is particularly attractive for recovering methane (primary component) and carbon dioxide (secondary component) from landfill gas.

摘要： Gas mixtures are separated on a two column molecular sieve pressure swing adsorption (PSA) system to produce an enriched gas stream. This process features the use of a product gas purge, an inlet vent gas and feed gas for the repressurization of a regenerated column and does not require vacuum or an air receiver.

摘要： Gaseous mixtures are separated on a two zone (two columns connected in series per zone) carbon molecular sieve pressure swing adsorption system to produce a gas stream enriched in at least one component. This process includes the partial pressurization of an absorbent zone with lean gas in the range of 40 to 90 percent of the adsorption pressure.

摘要： The water content of a gas rich in nitrogen obtained by vacuum swing adsorptive fractionation of ambient air, is removed in a companion drying system operated in association with the air fractionation system but at independent cycle time period, wherein water-laden nitrogen from the air fractionation system is passed through a dessicant bed of solid water-retaining adsorbent in said drying system while withdrawing dry nitrogen therefrom, and the adsorbed water is subsequently removed from said dessicant adsorbent by regeneration thereof with effluent obtained in rinsing the air fractionating column with desorbed process nitrogen.
