The Yanchang Petroleum Yan’an Energy Chemicals coal chemical project will see the construction of new facilities. Author/Source: Coal Chemicals 114 Date: 2019-08-22 Clicks: 145 On August 17, Yanchang Petroleum Yan’an Energy Chemicals held an expert review meeting for the feasibility study report on the membrane separation/PSA facility in Xi’an. This meeting was organized by the Department of Science, Technology and Quality Management, with 14 participants including industry experts as well as representatives from the Production Planning Department, the Natural Gas Conversion and Synthesis Center, the EPDM Butanol Center, and the Electrical and Instrumentation Center. After reviewing the feasibility study report submitted by the design unit, the expert group concluded that the proposed plan, the accompanying facilities, and the depth of preparation of the report generally met the requirements, and approved it in principle. They also provided suggestions and recommendations regarding aspects such as process design, equipment, electrical systems, instrumentation, and investment estimates, urging the design unit to make further improvements. This review meeting will lay a solid foundation for the construction of the membrane separation/PSA unit. Once built, this unit will enable the decoupling of the gasification conversion rate from the hydrogen-to-carbon ratio control in the butanol/2-PH unit, thereby ensuring long-term stable operation of the butanol/2-PH unit and achieving higher methanol production through increased coal input. Since the main production process was completed and trial production began in September 2018 for the coal, oil, and gas resource comprehensive utilization project of Yan’an Energy Chemical Co., Ltd. under Yanchang Petroleum, as of the end of July 2019, a total of 595,100 tons of various chemical products had been produced, generating sales revenue of 3.272 billion yuan; meanwhile, several industry records were broken. At present, except for ACO and EPDM, all other units are ready for stable operation at full capacity. Among them, units such as conversion synthesis and MTO operated at a load of over 100%, while the butanol co-production 2-PH unit produced high-quality butanol with a purity of 99.5% and high-quality 2-PH with a purity of 94.12%. From January to July, a total of 595,100 tons of various chemical products were produced, of which 370,700 tons were polyolefins. The Yan’an Energy and Chemicals Coal, Oil, and Gas Resources Comprehensive Utilization Project involves the construction of 8 main production units, including ones for manufacturing 1.8 million tons of methanol, 600,000 tons of methanol derivatives, 400,000 tons of refinery light oil products, 450,000 tons of polyethylene, 250,000 tons of polypropylene, 200,000 tons per year of butanol, 80,000 tons per year of 2-PH (dipropyl heptanol), and 25,000 tons per year of EPDM rubber), along with the associated utility systems. The estimated investment for this project is 21.6 billion yuan. Among them, butanol, 2-PH, and EPDM fill the gap for similar products in Shaanxi Province. At the same time, the plants for co-producing 2-PH from butanol, catalytic olefin production from light oil (ACO), and the production of EPDM via solution polymerization are the world’s first of their kind.
