Yulong Petrochemical’s coal-to-hydrogen production uses multi-nozzle gasification. Author/Source: Date: 2021-01-18. Clicks: 5. According to Multi-Nozzle, from January 11 to 15, 2021, the review meeting for the gasification process package of the coal-to-hydrogen unit as part of the first phase of Yulong Petrochemical’s integrated refining and chemical processing project was held as scheduled. The participating parties include the owner Shandong Yulong Petrochemical, the patent holder Yankuang Guotuo together with East China University of Science and Technology, and the design institute SEI (Sinopec Engineering Construction Company). The Yulong Island refining and chemical integration project (Phase I) will have a crude oil processing capacity of 20 million tons per year. Gasification employs a multi-nozzle opposed gasification technology. The inner diameter of the gasification furnace is 3880 mm, with a design pressure of 6.5 MPa; it operates in a 2-operational-1-backup configuration. According to the environmental impact assessment document for the Yulong Island petrochemical integration project, as published by the Ministry of Ecology and Environment in July 2020, the coal-to-hydrogen production process involves multi-nozzle water-coal slurry gasification, three-stage sulfur-tolerant shift reaction, low-temperature methanol washing to remove acidic gases, and PSA for hydrogen purification. The designed capacity of the plant is 220,000 standard cubic meters per hour of hydrogen with a purity of 99.9%, which corresponds to 114,000 tons of pure hydrogen per year. At the same time, 426,000 tons per year of fuel gas (equivalent to standard oil) is produced. In July 2020, Shandong Yulong Petrochemical signed licensing agreements for multi-nozzle opposed gasification technology with Yankuang Guotuo and East China University of Science and Technology.
