【Multiple Nozzles】Latest Progress on the Shandong Yulong Island Coal Gasification for Hydrogen Production Project Author/Source: Gasification World Date: 2023-03-24 Clicks: 14 On March 20, the four gas release buffer tank units for the Shandong Yulong coal-based hydrogen production project, constructed by the Tianjin branch of China National Chemical Engineering Group Corporation Limited, were successfully installed in place. This lifting operation marks the beginning of the equipment installation work for the project, signaling that all the units and components of the project have entered the civil works and safety preparation phase. The coal-to-hydrogen production phase of the first phase of the Yulong Island integrated refining and chemical project utilizes three multi-nozzle gasifiers, with two in operation and one as a backup. The coal-to-hydrogen 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 production capacity is 260,000 m3/h for hydrogen and 200,000 m3/h for fuel gas. Project Overview: The Yulong Island Refining and Chemical Integration Project (Phase I) aims to build 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 facility 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. Shandong Yulong Petrochemical Project (Phase I) Plan: Polypropylene – 2 sets of polypropylene plants with a capacity of 400,000 tons per year, using the ST II process ； 2 sets of 400,000 tons/year polypropylene plants, using the Novolen process ； 1 set of a 300,000-ton/year polypropylene plant, using the Horizone process. Polyethylene: 1 set of LDPE plant with a capacity of 200,000 tons per year, 1 HDPE plant with a capacity of 1.1 million tons per year, and 1 LDPE/EVA plant with a capacity of 600,000 tons per year
