Submarine atmosphere regeneration

Abstract

In the paper was presented introduction of Polish soda lime (produced by the Chemical Company Dwory SA) successfully used for filling the carbon dioxide scrubber of a regeneration system built in K0BBEN class submarines for eliminating carbon dioxide from its atmosphere without any additional construction changes. Research on the atmosphere regeneration was carried out on a K0BBEN class submarine. The initial C0₂ concentration was achieved by releasing content of two cylinders filled with C0₂/N₂ gas mixture. Fur- ther C0₂ emission adequate to its maximum production by the ship's crew during breathing, was simulated by means of a constant emission simulator.The time of the preventive operation amounted to about 2 hours. The dynamic absorbing capacity of carbon dioxide was validated experimentally.
