The general contracting party for the PSA hydrogen production project in Shandong has started work on it. Author/Source: Huahua Network – Coal Chemicals. Date: 2021-06-08. Clicks: 1. Recently, the commencement ceremony for the PSA unit of Yulong Island Petrochemical Integration Project (Phase I) carried out by Shandong Yulong Petrochemical Co., Ltd. was held at Southwest Chemical Research and Design Institute Co., Ltd. The project team from the owner, Yulong Petrochemical Refining Project, the SEI project team from the overall design institute, and the project team from Southwest Chemical Engineering, the EP general contractor, were all present at the meeting. This meeting clarified and confirmed all the key information required to launch the project, ensuring its rapid and high-quality progress. In early May, Southwest Chemical Research and Design Institute Co., Ltd. won the bid for six large-scale PSA units as part of the 20 million-ton petrochemical integration project (Phase I) on Yulong Island – namely units #1-4 for PSA processing, a PSA unit for hydrogen production from methanol, and a PSA unit for hydrogen production via coal gasification. The total hydrogen production capacity of these units is 850,000 Nm3/h. Two of these units for purifying hydrogen via PSA using reformed gas can produce 230,000 Nm3/h of hydrogen each, while the unit for purifying hydrogen via PSA using high-pressure coal-based gas can produce 200,000 Nm3/h of hydrogen. For the Shandong Yulong refining project, Southwest Chemical utilizes new technologies to extract hydrogen to the maximum extent from traditional fossil fuels and hydrogen-rich gases, thereby increasing the recovery rate, reducing the consumption of feed gas, and lowering energy consumption and carbon dioxide emissions. The main technologies include: the patented technology for alternating flushing of twin counter-current tanks ； Analytical design of large-scale PSA adsorption towers ； Erosion-proof zero-leakage programmable valve ； Intelligent control systems and expert diagnosis systems, etc ； High-pressure PSA system technology. Over the years, Southwest Chemical has built more than 100 large-scale PSA units as part of various refining and chemical processing projects, as well as coal chemical projects carried out by companies such as CNPC, Sinopec, CNOOC, Sinochem Quanzhou, Hengyi Brunei Petrochemicals, Shenhua Ordos Direct Liquefaction, Shenhua Ningxia Coal Indirect Liquefaction, and Shaanxi Coal Group. These units have provided important technical support for the development of oil refining and chemical industries on a scale of tens of millions of tons, as well as coal chemical industries on a scale of millions of tons. The Yulong Island refining and chemical integration project is located on Yulong Island in Longkou City, Yantai Province, Shandong Province, and is planned as a refining and chemical integration facility with an annual capacity of 40 million tons. The crude oil processing capacity of Phase 1 of the project is 20 million tons per year. The investment required for the project’s construction is approximately 127.4 billion yuan, with a construction period of 24 months. As a model for the transformation of old and new economic drivers as well as the adjustment of the industrial structure in Shandong Province, the construction of this project will facilitate the integration of 130 million tons worth of local refining capacity in the province. It holds great significance for promoting structural adjustments and upgrades within the industry, as well as for improving the level of integration in the refining sector.
