Hydrogen Separation & Purification

Hydrogen is a critical industrial raw material widely used in oil refining, coal chemical processing, and other industries. Lirun Technology has developed a hydrogen production process based on high-performance proprietary adsorbents, which efficiently extracts hydrogen from syngas, coke oven gas, and other hydrogen-containing mixtures. This process is characterized by:

· Simple flowsheet

· High product purity (up to 99.99%)

· High recovery rate (85–95%)

· Strong feedstock adaptability

It provides customers with significant energy-saving and efficiency-enhancing solutions.

PSA Hydrogen Principle

The system employs multi-component adsorption beds composed of activated carbon, silica gel, and molecular sieves. Under specific pressures, impurities from feed gases such as methanol cracking gas and ammonia purge gas are selectively adsorbed, while hydrogen—difficult to adsorb—passes through and is extracted as product gas from the top of the tower. This technology can handle various hydrogen sources, including FCC dry gas and water gas, achieving efficient hydrogen purification.
