EVALUATION OF LIQUID AMINE SYSTEM FOR SPACECRAFT CARBON DIOXIDE CONTROL

摘要

This report describes the results of analytical and experimental studies which were directed toward the acquisition of basic information on utilizing a liquid amine sorbent for in use in a CO2 removal system for manned spacecraft. Although liquid amine systems have been successfully used on submarines for control of CO2 generated by the crew, liquid amines could not be considered for spacecraft applications due to lack of development of satisfactory rotary phase separators. Recent developments in this area now make consideration of liquid amines practical for spacecraft system CO2 removal. Also, the Naval Research Laboratory has identified a new type of amine solution which offers potential important advantages over standard monoethanolamine-water solutions.
