Comparative analysis of nitrogen-using technologies for propellant dehydration at ground-based cosmodrome complexes

Characteristics of technological processes for dehydrating the hydrocarbon propellant are considered, which are based on application of propellant barbotage and cyclic technology of discharge–supersaturation with the use of dry nitrogen. Specific expenditures of nitrogen and time for performing operations of propellant dehydration are compared, and recommendations are given on their application in complexes of the propellant storage and preparation and at launching sites of cosmodromes.
