Recently, the 3,000 Nm3/h high-purity hydrogen production project of Dongfang Hope Chongqing Wansheng Coal Chemical Co., Ltd. (referred to as “Wansheng Coal Chemical”) was successfully put into trial operation, producing hydrogen with a purity of up to 99.999%. This level of purity meets the national standards for high-purity hydrogen as well as the quality requirements for hydrogen used in fuel cells. The Wansheng Coal Chemical high-purity hydrogen project uses the waste gas generated in the company’s methanol synthesis process as raw material; through a PSA system, the impurity content is reduced to below one part per million, resulting in high-purity hydrogen with a purity of 5 nines, or 99.999%. This project has significantly increased the added value of the exhaust gases released, extended the company’s green industrial chain, and also provided the company with another green, low-carbon product. The project will be constructed within the existing plant site of Chongqing Wansheng Coal Chemical Co., Ltd. Construction scale and contents: The project covers an area of 1,828.3 m2, and it involves the construction of one set of pressure swing adsorption hydrogen production (PSA-H2) unit, equipped with 6 adsorption towers as well as corresponding buffer tanks, compressors, hydrogenation columns, safety instruments, etc., to achieve a hydrogen production capacity of 3,000 cubic meters per hour of high-purity hydrogen.
