Hydrogen is an important green and clean energy and chemical raw material, which has been widely used in many fields. Industrial hydrogen production process methods mainly include hydrocarbon steam reforming, heavy oil or coal gasification, methanol steam reforming and ammonia decomposition.etc. The hydrogen obtained by these methods is not high purity and needs further purification. In addition, other mixed gases of hydrogen-containing need to be recovered and purified such as refinery catalytic cracking dry gas, refinery reforming tail gas, synthetic ammonia purge gas, methanol tail gas, crude hydrogen from membrane separation etc.To do this, in response to Meet technology and market demand of purify hydrogen, after years of research and development and industrial application practice, the company now has pressure swing adsorption and membrane separation to purify hydrogen technology, which can achieve high efficiency, high yield, low energy consumption and low cost to obtain high-purity hydrogen products from the hydrogen-containing mixed gas .
