AlwaysFree: Hengli Petrochemical Commissions New PSA Units

Hengli Petrochemical has commissioned seven new polybed pressure swing adsorption (PSA) units at its Hengli Petrochemical Industrial Park on Changxing Island in Dalian, in the Chinese province of Liaoning. The skid-mounted PSA units are provided by Honeywell UOP LLC and capable of producing about 1.4 million cubic metres of high-purity hydrogen every hour. The PSA units can yield hydrogen with a purity of more than 99.9% thanks to Honeywell UOP’s proprietary adsorbents which remove impurities from hydrogen-containing process streams at high pressure. The hydrogen can meet refining requirements to produce diesel, gasoline, jet fuel, and petrochemical feedstock.
