The total hydrogen production will reach 980,000 Nm3/h! Author/Source: Gas Separation Date: 2022-01-17 Clicks: 10 On January 13, 2022, Shandong Yulong Petrochemical Co., Ltd. issued a winning bid notice, announcing that Sinochem Southwest Chemical Research and Design Institute (hereinafter referred to as “Southwest Institute”) had won the bid for the PSA unit of the heavy oil-to-hydrogen production facility as part of the 20 million tons per year integrated refining and chemical processing project (Phase I) at Yulong Island. The designed hydrogen production capacity is 130,000 Nm3/h, with a design pressure of 5.8 MPa. To date, the total PSA hydrogen production volume of the first phase of Yulong Island project has reached 980,000 Nm3/h. In May 2021, Southwest Research Institute announced that it had won all bids in the international tender for six large-scale PSA units at the 20 million tons per year petrochemical integration project (Phase I) on Yulong Island – namely units Nos. 1-4# PSA, a methanol-to-hydrogen PSA unit, and a coal-to-gas combined hydrogen production PSA unit – resulting in a total hydrogen production capacity of 850,000 Nm3/h. Following the 6 large-scale PSA hydrogen production units installed by Yulong Petrochemical, the professional expertise and commitment to service demonstrated by Southwest Institute during the project construction were highly recognized by the client, who once again chose Southwest Institute as the supplier for the 7th high-pressure oil-based PSA hydrogen production unit. It is reported that Yulong Petrochemical relies on a combination of internal hydrogen extraction and external hydrogen production for its hydrogen supply. The 1-4# PSA hydrogen production units, the methanol-to-hydrogen PSA unit, and the coal-to-gas combined hydrogen production PSA unit, all of which are being constructed by the Southwest Plant, together with the PSA unit of the heavy oil-to-hydrogen combined unit that was won in this bid, will ensure an adequate supply of hydrogen for refining and hydroprocessing at Yulong Petrochemical. It is understood that over the years, the Southwest Research Institute has installed more than 100 large-scale PSA units in various refining and petrochemical projects as well as coal chemical projects operated by companies such as CNPC, Sinopec, CNOOC, Sinochem Quanzhou Petrochemical, Hengyi Brunei Petrochemical, Shenhua Ordos Direct Liquefaction, Shenhua Ningxia Coal Indirect Liquefaction, and Shaanxi Coal Group. These units have enabled China to fully replace and surpass foreign PSA technologies, providing important technical support for the development of China’s oil refining and petrochemical industries on a scale of tens of millions of tons, as well as its coal chemical industries on a scale of millions of tons.
