HYDROCARBON PROPELLANT PRODUCTION PLANT Russian patent published in 1998 - IPC

FIELD: PROPELLANT PRODUCTION. SUBSTANCE: plant contains: heat-mass-exchange apparatus for preliminarily preparing raw material connected with propellant composition preparation unit constructed in the form of rectification column; carbon adsorbers; adsorbers for drying and purifying propellants filled by synthetic zeolites; regeneration gas preparation unit; heat exchangers; and furnaces. Top outlet of rectification column is connected with bottom inlet of carbon adsorbers. On the propellant outlets from each type of adsorbers, filters are mounted. In the bottom part of each adsorber for drying and purifying propellants, NaA zeolite bed and above it CaA and NaN zeolites are placed. Regeneration gas preparation unit is either composed of adsorbers filled with zeolites or made in the form of nitrogen preparation unit. EFFECT: enhanced process efficiency. 6 cl, 3 dwg
