According to Honeywell, Hubei Sanning Chemical Industry Co., Ltd. will use Honeywell UOP’s Polybed Pressure Swing Adsorption (PSA) technology to supply high-quality hydrogen at its monoethylene glycol (MEG) plant at Zhijiang in China’s Hubei Province, which is used to produce MEG. Polyester resins, films and fibers are commonly made using MEG, that is manufactured from coal. The new PSA unit is designed to produce 165,000 cubic meters of hydrogen per hour.
Henry Liu, regional general manager for Honeywell UOP China, said, “This is the first application in China of the Honeywell UOP PSA technology in a MEG chemical plant. It demonstrates the flexibility of Honeywell UOP’s hydrogen technologies in a wide range of uses, including chemical manufacturing.”
Hubei Sanning has chosen the Honeywell UOP technology due to its unique features such as proven reliability, superior economics, and fast delivery and start up schedule. The UOP technology also features new UOP adsorbents that recovers hydrogen at very high levels, with the result, the PSA unit can produce hydrogen with purities as high as 99.9999 percent and makes it an excellent source for the production of high-quality monoethylene glycol.
Hubei Sanning, located near the Yangtze River, will be able to meet new environmental regulations with the use of PSA technology. The company has planned to modernize its production technology to high-pressure gasification and accommodate a new 600,000 tons-per-annum MEG plant expected to be in operation next year.
Hubei Sanning Chemical Industry Co., Ltd., founded in 1970, is a subsidiary of Shanxi Jincheng Anthracite Mining Group Co., Ltd. The company produces chemicals from coal and phosphorous, petrochemicals, and other fine chemicals, as well as hydrochloric acid, alcohols, ammonia, methanol, and fertilizers.
