摘要

The membrane hollow lumen pressurized air drying process comprises conveying permeate from the lumen of the dryer, feeding air and retentate into the framed stack and circulating around the membrane fiber outer peripheral skin at the fixed bed height from the pressurized air inlet up to the retentate outlet with permeate release from the skin at the periphery of the framed stack.
