MIL-P-24082C, MILITARY SPECIFICATION: PLANT, CARBON DIOXIDE REMOVAL, LIQUID ABSORBENT TYPE (MARK IIIB) (FOR SUBMARINES) (07 DEC 1981)., This specification covers Mark IIIB carbon dioxide (co2) removal plant, and test kit for the plant, capable of removing co2 from a submarine atmosphere and discharging this co2 overboard against variable submergence pressures. The co2 removal shall be accomplished by continuous absorption and desorption of the co2 in an aqueous solution of chelated monoethanolamine (MEA).
