Helium enrichment from natural gas by membrane solution

Helium gas is widely used in military industry, scientific research, petrochemical, refrigeration, medical, semiconductor, pipeline leak detection, superconducting experiment, metal manufacturing, deep-sea diving, high-precision welding, optoelectronic product and other high- tech industries. At present, China's helium reserves accounts for only about 2% of the world's helium, which is very scarce. Most of the helium used is imported from abroad.

Helium gas is mostly stored in natural gas, and its concentration is typically 0.1-1%. The extraction process is usually cryogenic separation, which is a very energy-consuming process. The gas membrane separation technology, with the feature of high perm-selectivity of helium over methane and nitrogen, can increase the concentration of helium gas more than 10-times, and greatly reduce the heat energy consumption of subsequent process. It is especially suitable for the recovery of helium gas in BOG exhaust air of LNG plant and helium concentration process of low helium gas.
