FIELD: chemical machine building, preferable, in rocket technique at preparing of components of rocket fuel having high boiling point. SUBSTANCE: drying of hydrocarbon rocket fuel is carried out by bubbling inert gas through said fuel, the process takes place till drops of free water are isolated from fuel. Final drying is carried out by feeding of cryogenic liquid being chemically neutral, the process takes place under layer of fuel by bubbling. EFFECT: improved efficiency. 2 dwg
