Recently, good news came from the coal-to-hydrogen project in Phase 1 of the Yulong Island refining and chemical integration project: the 35KV substation was successfully powered up in one attempt, marking the achievement of this important milestone. The 35KV substation of the Yulong Petrochemical coal-to-hydrogen project is a two-story building with a reinforced concrete structure, measuring 72m×36m. The main power distribution equipment in this substation includes 4 35KV oil-immersed transformers, 76 10KV medium-voltage cabinets, 4 sets of 10KV reactive power compensation cabinets, 8 10KV dry-type transformers, 124 0.4KV low-voltage cabinets, 11 control panels, 2 sets of DC panels, and 1 UPS system. The coal-to-hydrogen substation is the only substation in the entire coal-to-hydrogen plant, and it is responsible for distributing power throughout the plant. To ensure the quality of the nodes, the project department attached great importance to this task, mobilizing a team of skilled workers to work overtime and race against time. Within just 3 months, the installation of electrical equipment, the laying of cables between panels, and equipment debugging were completed. After several rounds of inspection and verification by the owner’s various departments, the project was successfully approved at the beginning of October. It is reported that the 35KV substation for coal-to-hydrogen production is the first substation on Yulong Island to successfully receive power supply. This successful power connection marks the full entry of the coal-to-hydrogen facility into the testing phase, providing strong support for the project’s handover. 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 internal diameter of the gasifier 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. 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 production facility with an annual capacity of 200,000 tons, 1 HDPE production facility with an annual capacity of 1.1 million tons, and 1 LDPE/EVA production facility with an annual capacity of 600,000 tons. The Yulong Island Integrated Refining and Chemicals Project (Phase I) is located on Islands 2 and 3 of Yulong Island in Longkou, Yantai City, Shandong Province. The investment required for this project is approximately 127.4 billion yuan, with a construction period of 24 months. The project plans to establish a crude oil processing capacity of 20 million tons per year, and will be equipped with a atmospheric distillation unit capable of processing 10 million tons per year, a vacuum distillation unit also capable of handling 10 million tons per year, units for light hydrocarbon recovery, desulfurization and dewaxing facilities, as well as residue hydrogenation units among other refining processes. It will also include chemical processing units for producing ethylene, hydrogenating cracked gasoline, carrying out aromatic extraction, butadiene extraction, and producing EVA/LDPE. In addition, there will be supporting utility systems, auxiliary facilities, as well as seawater desalination and intake/discharge systems. Project Background and Progress: In February 2019, the work report presented at the second session of the 13th Shandong Provincial People’s Congress stated that Shandong Province would make every effort to advance the preliminary work for the Yantai Yulong petrochemical integration project. To advance the implementation of the Yulong refining and chemical integration project, the People’s Government of Shandong Province decided to establish the Shandong Yulong Petrochemical Industrial Park (whose predecessor was the Longkou High-End Chemical New Materials Industrial Zone). This park was included in the \"Notice issued by the General Office of the People’s Government of Shandong Province regarding the publication of the list of the fourth batch of chemical parks and specialized chemical parks\", released by the General Office of the People’s Government of Shandong Province in June 2019. In August 2019, the People’s Government of Yantai issued a document titled \"Notice from the Office of the People’s Government of Yantai regarding issues related to the area and boundaries of the initial phase of the Shandong Yulong Petrochemical Industrial Park\", in which it was determined that the area of the initial phase of this industrial park is 35.23 square kilometers. On September 10, 2019, the People’s Government of Longkou City approved the overall plan for the Shandong Yulong Petrochemical Industrial Park with document number Longzheng Gui Zi [2019] No. 37. On September 11, 2019, the Shandong Provincial Department of Ecology and Environment issued its review opinions on the environmental impact assessment report for the same industrial park, using document number Lu Huan Shen [2019] No. 14. On January 26, 2020, the National Development and Reform Commission, the Ministry of Industry and Information Technology, and the National Energy Administration jointly responded to Shandong, agreeing to include the project as a reserve project in the \"Petroleum and Chemical Industry Layout Plan (Revised Version)\". On June 1, 2020, the National Development and Reform Commission, the Ministry of Industry and Information Technology, and the National Energy Administration, in their reply titled \"Reply on Changing the Yulong Island Refining and Chemical Integration Project (Phase I) from a reserved project to a planned project,\" approved the conversion of this project from a reserved project to a planned project. On June 2, 2020, the Shandong Provincial Development and Reform Commission issued the approval decision for the Yulong Island refining and chemical integration project (Phase I) (Lu Fa Gai Zheng Wu [2020] No. 73). On July 15, 2020, the official website of the Ministry of Ecology and Environment published the environmental impact assessment document for the \"Yulong Island Refining and Chemical Integration Project (Phase I)\\" construction project. Around September 27, 2020, the Geotechnical Survey Institute successfully secured a contract for the pile foundation work of the refining and chemical integration project (Phase I) of Shandong Yulong Petrochemical Co., Ltd.
