The installation of the two methanol tanks in the 191K tank area, which are part of the additional projects under the first-phase completion project of Yulin Energy Chemical Complex, has been completed. Author/Source: Refining & Chemical Industry Updates Date: June 12, 2020 Clicks: 110 On June 10, the installation of the two methanol tanks in the 191K tank area, undertaken as part of the EPC contract by Beijing Petrochemical Engineering Co., Ltd., was completed. Both tanks have a capacity of 35,000 cubic meters; the medium stored in them is methanol. They are of the internal floating roof type, with a diameter of 44.17 meters and a height of 29.895 meters. Its structure consists of a tank top plate, a grid structure, tube walls, a tank bottom, a platform, a spiral staircase, and carbon steel floating decks. The edge plates of the tank bottom are designed in an arch-shaped structure, while the middle plates are joined together by lap welding. The tube walls are composed of 13 separate plate sections. It is reported that the tank wall panels and roof are constructed using the inverted construction method; 82 lifting masts are evenly installed around the inside of the tank, along with 82 electric hoists capable of lifting 10 tons each, with truck cranes and loaders used to assist with the installation. During lifting, a dedicated person shall be assigned to give unified instructions and operate the control panel; two additional persons shall be responsible for monitoring the stress on the lifting chains throughout the process, to assist in completing the lifting task. The project team defined clear roles and responsibilities to ensure safety, assigned dedicated personnel for area management, which provided a guarantee for completing the installation tasks to high standards. At the same time, the completion of the installation of the two tank bodies has laid a solid foundation for the subsequent construction of the entire 191K tank area. Shaanxi Yanchang China Coal Yulin Energy Chemical Co., Ltd. is a large-scale chemical enterprise that utilizes coal, gas, and oil in integrated ways, established through a joint investment by Shaanxi Yanchang Petroleum Group and China Coal Energy. It was founded on May 24, 2010, with a registered capital of 10 billion yuan. In accordance with the requirements of the **Petrochemical Industry Adjustment and Revitalization Plan** and the **Overall Plan for Energy Development and Utilization in the Ordos Basin**, the project was launched to build 8 main production units, including ones capable of producing 1.8 million tons per year of methanol, 1.5 million tons per year of residue catalytic thermal cracking (DCC), 600,000 tons per year of DMTO, 2 x 300,000 tons per year of polyethylene (PE), 2 x 300,000 tons per year of polypropylene (PP), and 90,000 tons per year of MTBE, along with the necessary supporting utility systems. The estimated investment for the facility is 27 billion yuan, with 14 patented technologies from home and abroad being utilized. In November 2009, the project was designated as a \"Clean Coal Technology Demonstration and Promotion Project\" by relevant organizations such as the National Development and Reform Commission and the United Nations. The project is a key initiative of the Northern Shaanxi Energy and Chemical Industry Base, and it represents the first demonstration project for the comprehensive conversion of coal, gas, and oil by Yanchang Petroleum, enabling multiple co-productions across different stages of the production process. The first-phase project was completed and put into operation in July 2014, and transitioned from the construction phase to the production and operation phase in August 2015. The completion and improvement project for the first phase of Shaanxi Yanchang China Coal Yulin Energy Chemical Co., Ltd. (Yanchang Jingbian Phase II project) involves an investment of 14.413 billion yuan. Using coal and natural gas as raw materials, this project aims to build an integrated facility capable of producing 1.8 million tons per year of methanol, 600,000 tons per year of methanol-to-olefins products, 400,000 tons per year of polypropylene, and 300,000 tons per year of low-density polyethylene/ethylene-vinyl acetate copolymer (LDPE/EVA). The project is scheduled to be put into operation in the second half of 2020. Once operational, Yueneng Chemical’s polyolefin production capacity will reach 1.9 million tons per year, making it the largest polyolefin production project in Shaanxi Province at present.
