The comprehensive utilization project of coal, oil, and gas resources in Yan’an has entered the trial operation phase. Author/Source: Huahua Network – Coal Chemical Industry. Date: October 25, 2018. Clicks: 31. This project is a key initiative in Shaanxi Province; serving as a model for low-carbon economies, circular economies, and comprehensive resource utilization, it uses coal, natural gas, and low-quality light oils produced by Yanchang Petroleum as raw materials to manufacture various chemical products such as high-quality polyethylene, polypropylene, and butanol. The project is now in the trial operation stage, and once fully operational, it is expected to generate an annual output value of 11.3 billion yuan. At 11:00 on October 19, the 400,000 tons per year light oil processing unit (ACO) of the Yanneng Chemical Project, which was EPC-general contracted by Beijing Petrochemical Engineering Co., Ltd., began to produce qualified ethylene and propylene products. At present, all performance indicators of the unit meet the expected standards; it is operating smoothly with normal process parameters. Su Tao, deputy manager of the light oil processing center at Yan’an Energy and Chemical Co., Ltd., explained that starting from September 17th, thorough preparations were made to ensure a successful trial run for feeding materials into the ACO (catalytic olefin production) process. The Yan’an coal, oil, and gas resources comprehensive utilization project makes use of 12 patented and proprietary technologies. In terms of the utilization of light hydrocarbon resources, it employs the world’s first advanced catalytic olefin production (ACO) technology, which allows for the full exploitation of these resources; this approach replaces the traditional high-temperature decomposition method by enabling the production of high-quality ethylene and propylene at lower temperatures. It has advantages such as a wide range of applicable raw materials, high olefin yield, low coking rate, low carbon dioxide production, and energy savings. Kou Yuxin, deputy manager of the Olefin Polymerization Center at Yan’an Energy and Chemical Co., Ltd., explained that currently the daily processing volume of polypropylene is around 700 to 800 tons, while that of polyethylene is nearly 1,000 tons per day. The daily sales revenue exceeds 10 million yuan. Once the plants are operating at full capacity, the total daily production of polyolefins could reach over 2,000 tons, with an output value of more than 20 million yuan. The Yan’an Coal, Oil, and Gas Resources Comprehensive Utilization Project is located in Luoyang Village, Fuxian County. It was fully launched in September 2015, with the construction of 8 main production units, including ones for producing 1.8 million tons per year of methanol, 600,000 tons per year of methanol derivatives, and 400,000 tons per year of light oil, along with supporting utility systems. The project uses coal, natural gas produced by Yanchang Petroleum, as well as low-quality light oils from its refineries as raw materials to produce various chemical products such as high-quality polyethylene, polypropylene, and butanol, which are then used to manufacture products like woven materials, films, pipes, wires, and cables. The project is now in the trial operation phase, with all technical staff at the plant working overtime to ensure the smooth operation of the equipment.
