Ten years of rapid development in chemical engineering technology – praising the prosperity and strength of modern China. This is just a starting point; more participation from everyone will make things even more interesting. With you here, HaiChuan becomes even better. [Ten years of progress in chemical engineering equipment] – continuous updates and summaries available; feel free to join the discussions: https://bbs.hcbbs.com/thread-3576046-1-1.html. We encourage everyone to participate more actively in the forum discussions to enhance our awareness of quality and promote high-quality development. ----------------------------------------- On August 25, 2023, China National Petroleum Corporation’s intelligent alkaline electrolysis hydrogen production system, developed with independent intellectual property rights, was successfully put into operation at Dushanzi Petrochemical Company. It is reported that this demonstration project for producing hydrogen through water electrolysis is used in oil refining processes; it helps to reduce the consumption of fossil fuels and the emission of greenhouse gases such as carbon dioxide, thereby contributing to the achievement of carbon peak and carbon neutrality goals. The project owner is the Dushanbe Petrochemical Branch of China National Petroleum Corporation, while the hydrogen production system was developed jointly by the Shenzhen New Energy Research Institute of China National Petroleum Corporation, the Dushanbe Petrochemical Company, China Global Engineering Corporation, and Kunlun Digital Technology Co., Ltd. According to the information published by Dushanzi Petrochemical, the industrial trial of the alkaline electrolysis water hydrogen production system carried out by the Dushanzi Petrochemical Branch of China National Petroleum Corporation involved a total investment of 26.46 million yuan, with 54,600 yuan allocated to environmental protection measures. The project is located in the reserved area to the north of the 35KV North Substation in the old refining area of the Dushanzi Petrochemical Branch. A new hydrogen production test facility using the alkaline water electrolysis process will be built there, with a hydrogen production capacity of 1000 Nm3/h; this facility is arranged in an east-west orientation. The total area covered by the facility is 2400 m2. To the east lie the 800,000 tons/year catalytic gasoline hydrogenation unit and the 1 million tons/year wax oil hydrogenation unit. To the west and north are reserved areas, while to the south is the 35KV North Substation. The plant area is to be constructed in two phases. The area for Phase 1 of the plant is 1,365 m2, while the reserved land area for Phase 2 is 1,035 m2; the land used for this project corresponds to the area of Phase 1. Within the first-phase plant area, the various skids are arranged in a linear pattern; from west to east, they are as follows: transformer, electrical cabin, electrolyzer, hydrogen production frame, purification frame, auxiliary facilities skid, and pure water machine skid. The plant’s pipe gallery is connected to the system pipe gallery on the east side. This project will industrialize the water electrolysis hydrogen production technology owned by CNPC’s independent intellectual property, to facilitate its subsequent widespread application. The utility and auxiliary systems for this project rely on the existing facilities of Dushanbe Petrochemical.
