Abstract
A plurality of selectively permeable membrane cells are mounted in parallel spaced-apart relationship to form a stack. Each cell includes a substrate and selectively permeable membranes positioned on the major surfaces thereof. The substrates are provided with flow ports at alternate end portions to provide a series flow path through the stack which is sealed by peripheral gasket members and end plates. The stack is adapted for use in pressure and vacuum gas enricher systems.
