【Ten Years of Rapid Development in Chemical Equipment】Tianeng Coking Co., Ltd.’s Hydrogen Purification Project from 2017 to 2021

Thread Content

Witnessing the ten-year rapid development of chemical processing equipment, I praise the prosperity and strength of modern China. Wishing everyone a happy New Year, and may their families be safe and healthy. I hope this contribution will encourage more people to participate; with your involvement, Haichuan becomes even better. Everyone is welcome to join in the discussions on this forum. ----------------------------------------------------- During the coking process, gas is produced, and after removing gases such as ammonia, nitrogen, benzene, and methane, a nitrogen-hydrogen gas with 80% purity is obtained. Guizhou Panjiang Electric Power Tianeng Coking Co., Ltd. upgraded the hydrogen production system of its existing 50,000-ton-per-year benzene hydrogenation plant by adding purification and compression processes. The nitrogen and hydrogen exhaust gases from the LNG unit enter the compressor through pipelines; the gas, once pressurized there, is then routed to the hydrogen production unit via control valves. Through the pressure swing adsorption process, the nitrogen and hydrogen gas with a purity of 80% is converted into hydrogen with a purity of 99.999%. On February 28, 2021, Guizhou’s first hydrogen production (hydrogen extraction) demonstration project – the hydrogen purification project at Guizhou Panjiang ETP Tianneng Coking Co., Ltd. – was completed and put into operation, capable of producing 600 cubic meters of high-purity hydrogen per hour. This project is a key demonstration project for the new energy and chemical industry in Liupanshui City, providing strong gas supply support for the development of the hydrogen energy industry there as well as across the entire province.
