    摘要： A process and apparatus for separating gaseous mixtures by a pressure swing adsorption technique. One or more adsorbent beds are employed which operate on a cycle comprising the successive steps of adsorption, vacuum regeneration, and backfilling. The pressure in the bed(s) during backfilling is sensed, backfilling is ceased when such pressure reaches a predetermined level, and the regeneration step is controlled to occupy a constant period of time. The described process is able to maintain a substantially constant output flow and product purity despite the changes in adsorption capacity of the bed(s) which occur under fluctuating ambient temperatures.

    摘要： In a gas separation process a pressurized gaseous mixture is passed through a first bed of adsorbent while a second bed is being regenerated by desorbing gas therefrom and venting or discharging such gas from the second bed. The adsorbent is of such a character that one component of the gaseous mixture is preferentially adsorbed. The non-adsorbed component or components are collected as product. After a chosen time flow of gas into the first bed and out of the second bed is stopped, and the two beds are placed in communication with one another through a flow restrictor means so as to reduce the pressure difference therebetween. The flow restriction means is effective to prevent fluidization of the beds. The intercommunication between the two beds is stopped before the pressure difference therebetween has been eliminated and the gas mixture is then passed through the second bed, while the first is regenerated. The pressure difference between the two beds is then reduced and the cycle of operations repeated.

    摘要： A process for increasing the proportion of a gas in a gaseous mixture of which it is a component. The gaseous mixture is allowed to be drawn through an adsorbent bed in a substantially unpressurized condition by the action of a reduced pressure applied to an outlet of the bed. The bed is then regenerated prior to a further admission of the gaseous mixture thereto.

    摘要： A portion of a component of a gas stream is condensed with the remaining non-condensed gas stream being passed to an adsorber. The remainder of the component in the non-condensed stream is adsorbed in the adsorber and in a later stage of the adsorber cycle, the adsorbed component is desorbed and supplied to the inlet of a condenser together with the gas stream to promote condensation of the component by providing an increased concentration of the component in the gas stream.

    摘要： A compressed gas mixture, for example air, is passed through one of beds 12 and 14 of adsorbent that selectively adsorbs oxygen from the air. Unadsorbed nitrogen-enriched gas flows into a buffer vessel 28, from which product gas is withdrawn through pipeline 30. While one of the beds 12 and 14 is adsorbing oxygen for air the other is being regenerated, and during this period the communication between the beds is denied. At the end of a chosen period of time the beds are placed in communication with one another by opening valves 54 and 56. Then the bed that was previously being regenerated is placed in communication with the source of compressed air and the other bed regenerated. The period of intercommunication between the beds lasts for as long as it takes the volume of product gas as measured by an integrating flow meter 31 from the start of the preceding adsorption step to reach a chosen value. The apparatus is able to supply nitrogen of a chosen purity at a variable flow rate.

    摘要： A process for increasing the proportion of a gas in a gaseous mixture comprising such gas and at least two other constituents. The gaseous mixture in a substantially unpressurized condition is drawn successively through two beds of absorbent which adsorbs the two other constituents respectively by the action of a reduced pressure applied to an outlet of the second adsorbent bed in the series. The beds are then regenerated prior to a further admission of gaseous mixture thereto.
