Gas Composition Support Aids for Space Vehicle Compartments Based on CO2 Hydrogenation, H2O Electrolysis, CO2 Removal and Concentration

Consideration is given to Gas Composition Support Aids (GCSA) for habitable space station based on CO₂ removal and concentration, CO₂ hydrogenation, water electrolysis

by the example of Life Support System Module (LSSM) of the International Space Station Alpha Russian Segment.

Using Life Support System Module, for the first time an attempt was made to integrate the process of oxygen recovery from CO₂ based on Sabatier reaction into a common processing cycle with the aim to use it in real flight conditions.

The article describes the problems to be solved by means of an interaction of the above subsystems; the principles of systems and control interaction developed; the problems that arose during development of a given technological process; also mention was made of the points that are to be settled during development and conduct of tests.
