초록 ▼

Membrane permeation processes to produce oxygen-enriched gas from atmospheric air are improved by feeding the air to membrane cells divided into two groups, independently withdrawing the permeate output from the two groups of cells into two conduits containing restrictions, and referencing the pressure of one output against the other. A subsequent imbalance of pressure between the two permeate outputs indicates a membrane leakage in one of the two groups of cells.

대표청구항 ▼

In a membrane permeation process to produce oxygen enriched gas from atmospheric air comprising delivering a flow of atmospheric air to an array of series flow, selectively permeable membrane cells having a greater permeability of oxygen relative to nitrogen and maintaining a pressure differential across said array to produce an oxygen enriched permeate therethrough, the improvement for controlling and detecting membrane failure comprising: i. dividing the selectively permeable membrane into two groups of cells; ii. independently collecting the oxygen-enriched permeate output from each of said groups of cells; iii. passing each collected permeate output through independent conduit means including means for restricting the flow of said oxygen enriched permeate output to initially produce zero pressure differential between each conduit means, said pressure being measured in each conduit means at a location upstream of the flow restricting means; iv. continuously determining the presence or absence of a pressure differential between said conduit means; and v. discontinuing the process when a pressure differential is determined to exist between the conduit means indicating a membrane leakage failure in one of the two groups of membrane cells.
