Title:
METHOD AND APPARATUS FOR CONTROLLING PURITY OF PRODUCT BY PRESSURE SWING ADSORPTION
Document Type and Number:
Japanese Patent JPS6388015
Kind Code:
A
Abstract:
A process for controlling the level of impurity in a gas product stream from a pressure swing adsorption process including a cocurrent depressurization step, which comprises: (a) sensing a physical characteristic of the effluent from the cocurrent depressurization step; and (b) taking a corrective action responsive to the sensed characteristic, the corrective action being effective to vary the impurity concentration in the product gas in the direction necessary to obtain desired product purity. Apparatus therefor comprises means for sensing the physical characteristic and means for taking the corrective action. t
