Methane extraction technology – coalbed methane
At present, both at home and abroad, the main method for separating oxygenated coalbed methane is membrane separation, oxygen removal method, pressure swing adsorption (PSA) method, direct liquefaction method. After comprehensive comparative study of other low-enrichment gas separation technologies, Huaxi, based on its own low-concentration gas development technology, with complete analysis of the properties of the source gas, adopted pressure swing adsorption technology to separate CH4 and N2/O2 under micro-pressure conditions.
Gas with low concentration and methane content of 10 to 15% can be enriched up to 30% at a time for combustion and power generation, as well as secondary enrichment for natural gas production.
Installation scale: 2000~30000nm³/h.

Hydrogen production by conversion of light hydrocarbons with steam
The production of hydrogen from natural gas consists of two parts: the conversion of gas vapor into converted gas and the purification of hydrogen using the PSA method. After compression and desulfurization, natural gas is mixed with water vapor. Under the action of nickel catalyst at a temperature of 750~850℃, natural gas is converted into converted gas consisting of hydrogen, carbon monoxide and carbon dioxide. The converted gas can be further converted into hydrogen and carbon dioxide by conversion technology, then the converted gas or reformed gas is purified and separated by PSA method to produce high purity hydrogen.
