The semi-coke gas PSA hydrogen production and desorption gas and acid gas desulfurization device constructed by our company for Shaanxi Dongxinyuan Chemical Co., Ltd. is a coal chemical industry comprehensive utilization circular economy project. The total investment in the first phase of the project is 3.661 billion yuan, and the construction scale is 1.2 million tons/year blue carbon, 20,000 tons/year magnesium metal and 500,000 tons/year coal tar hydrogenation.

Our company undertakes the construction of semi-coke gas PSA hydrogen production and desorption gas and acid gas desulfurization equipment in the coal tar hydrogenation section. The processing capacity is: 130,000Nm3/h semi-coke gas; product hydrogen amount: 25,000Nm3/h, desorbed gas desulfurization after desulfurization to remove magnesium metal and combustion furnace, sulfur product is 352kg/h.

The project started in May 2014. So far, the device has completed the stand-alone test run, process piping purge, and electrical, instrumentation and automatic control system commissioning, and the project has entered the final stage of the test run.
