The world's largest coal-to-hydrogen PSA unit starts in Shaanxi province, China
The world largest coal-to-hydrogen pressure swing adsorption (PSA) unit has successfully started in Qingshui Industrial Park, Yulin Economic and Technological Development Zone, Shaanxi Province on September 12, 2022.
Using coal as a raw material, the plant has a total hydrogen production capacity of 350,000 tonnes per year.
This coal-to-hydrogen plant adopts pressure swing adsorption technology developed by Southwest Research and Design Institute of Chemical Industry, a research institute affiliated with Sinochem, a state-owned chemical giant.
The PSA unit is a part of Yulin Chemical's demonstration project of new chemical materials for the separative utilization of coal-the 1.8 million mt/year monoethylene glycol plant.
Yulin Chemical, a company of Shaanxi Coal and Chemical Industry Group, is now testing the coal gasification unit, and is expected to get MEG products in October at its 600kt/year No.1 syngas-based MEG unit of its 1.8 million mt/year plant.
