Significant progress has been made in chemical technology over the past decade; let’s praise the prosperity and strength of modern China. By contributing our ideas, we can foster more active participation from everyone. The HaiChuan forum becomes even better with your involvement – we welcome everyone to join in the discussions and exchanges. Everyone should pay attention to safety and know how to handle emergencies. ********************************************* Yan’an Energy Chemical Co., Ltd., a subsidiary of Shaanxi Yanchang Petroleum (Group) Co., Ltd., was established in September 2009. It is responsible for the development of projects that make use of coal, oil, and gas resources in Yan’an, as well as for the operation and management of these facilities once they are built. The Yan’an Coal, Oil, and Gas Resources Comprehensive Utilization Project is the largest energy and chemical project invested in by Yanchang Petroleum Group in Yan’an. Located in the Luo River valley in the southern part of Fuxian County, Shaanxi, the project uses associated gas from Yanchang Petroleum’s own oil fields, light oil from refineries, and coal as raw materials. It involves the construction of 10 sets of processing units capable of producing 1.8 million tons per year of methanol, 600,000 tons per year of products derived from methanol, 400,000 tons per year of light oil products, 450,000 tons per year of polyethylene, 250,000 tons per year of polypropylene, 200,000 tons per year of butanol, 80,000 tons per year of dipropyl heptanol, and 50,000 tons per year of EPDM rubber. Additionally, the project includes supporting infrastructure and facilities as well as external engineering works. The light oil processing unit (ACO unit), as one of the main production facilities at Yan’an Energy Chemical Company, not only supplies raw materials for the downstream olefin polymerization units but also provides some raw materials for the EPDM rubber production units. This facility utilizes a new hydrocarbon catalytic cracking technology jointly developed by the American company KBR and the South Korean company SK. It is capable of processing 400,000 tons per year of light hydrocarbon feedstocks such as naphtha, and can produce 151,000 tons per year of polymeric-grade ethylene and 126,000 tons per year of polymeric-grade propylene. At the same time, high-purity hydrogen, methane hydride, and crude pyrolysis gasoline are produced as by-products.
The ACO unit is currently the world’s first unit for the processing and utilization of light oil. ACO catalytic cracking technology replaces the traditional high-temperature steam cracking process by using catalytic reaction techniques to produce high-value materials such as ethylene and propylene at lower temperatures, thereby reducing energy consumption and CO2 emissions. It plays a crucial role in improving the comprehensive utilization rate of resources, saving energy and reducing consumption, expanding the industrial chain, and enhancing the overall energy efficiency and profit potential of the Yan’an petrochemical projects.

The project was EPC-general contracted by Beijing Petrochemical Engineering Co., Ltd. Construction commenced on September 11, 2015; the plant was successfully delivered at the end of 2017, and single-unit testing began in the first half of 2018. On September 2, the MTO and olefin separation units were successfully started up for the first time! On May 23, 2018, the lining installation and furnace charging operations for China’s first ACO unit were officially commenced.
【Ten Years of Great Progress in Chemical Technology】062 – The first domestic experimental plant for producing olefins through crude oil cracking was successfully put into operation from 2021 onwards. https://bbs.hcbbs.com/thread-3644163-1-1.html (Source: Huahai Chuanliu – Haichuan Network)
