MEMBRANE-BASED GAS SEPARATION PROCESS USING EJECTOR-DRIVEN GAS RECYCLE
摘要
A gas separation process that utilizes ejector recycle with a membrane separation step in combination with a second separation step. The second separation step may be a second membrane separation, or may involve a different type of separation process. At least a portion of the non-product (i.e. residue) stream withdrawn from the second separation step is directed back to the ejector to form a processing loop. The ejector drives the gas flow in the loop and recycles the non-product stream to the first separation step.
