ENERGY SAVING TECHNOLOGIES IN INSTALLATIONS FOR HIGH PURITY NEON AND HELIUM PRODUCING

Classical technology of neon-helium concentrate is considered. The necessity to reduce the specific energy consumption for the light inert gases is substantiated. The reserves of reducing the operating costs in the processing stream stripping are identified. It was proposed to include a membrane module in the scheme, wherein neon stream is separated and simultaneously the mixture is enriched with helium. Cost effectiveness of helium extraction technology is enhanced by increasing the duration of cryogenic adsorbers cycle and reducing the number of compressors.
