Development of a Permselective Membrane System for Continuous Carbon Dioxide Control
Abstract
An immobilized liquid film of an aqueous bicarbonate/carbonate solution, and including a catalyst for the hydrolysis of CO2, has been incorporated into a system for removal of CO2 from a life-supporting environment in space. A method of packaging the membrane is described. A one-man system, requiring 18.3 square yards of membrane, was constructed and tested. Approximately the same membrane area is required for both spacecraft cabin control and for astronaut extra-vehicular back-pack application. Permeation results are given for a variety of conditions. Virtually no oxygen is lost through the membrane, and the anticipated system has the advantage of not requiring regeneration or replacement of any components.
