Progress on the construction of the 500,000 tons/year coal-based ethanol project at Yushen Energy Chemicals, Yanchang Petroleum / Author/Source: Chemical Industry Network – Coal Chemicals / Date: 2022-01-17 / Clicks: 10. Recently, all 4 imported pumps for the ethanol production unit of this project have arrived. Thus, out of the 268 mechanical and electrical devices in the ethanol unit, all except for the ethanol dehydration unit (PK-401, including its associated equipment) have now been delivered. It is reported that the 4 imported pumps for the ethanol plant (dimethyl ether transfer pumps P-201A/B and methyl acetate feed pumps P-203A/B) are from the German company Hermetic Pumpen GmbH. Due to the impact of the pandemic, their arrival at the site was delayed by one month compared to the original plan. The arrival of the 4 imported pumps marks a new milestone in the construction of the ethanol production facility for the Yushen Ethanol project, and it also lays a solid foundation for the smooth installation of the subsequent process pipelines. Recently, the primary power supply was successfully established at the methanol substation and the demineralized water substation of the Yushen Energy Chemical Ethanol project, providing a prerequisite for the smooth commissioning of the methanol plant and the power station. It is reported that the methanol substation consists of 23 10kV high-voltage distribution cabinets, 4 sets of 10kV frequency converter cabinets, 2 sets of 10kV capacitor compensation cabinets, and 2 dry-type transformers with a capacity of 1600 kVA, and it is responsible for supplying power to the purification equipment in the methanol area ； The desalination water substation is equipped with 4 dry-type transformers. The power supply for these transformers comes from the 10kV Phase 1 and Phase 2 circuits of the #2 circulating water substation; a dual-circuit power supply system is used to ensure reliability of power supply. The 4 dry-type transformers supply power to Phase 1, Phase 2, Phase 3, and Phase 4 at 400V each. These four power phases are primarily used to supply power to the facilities within the station as well as to dozens of desalination water pumps. The Yushen 500,000 tons per year coal-based ethanol project is currently the largest project in the industrialization of coal-based ethanol technology. With a total investment of 6.98 billion yuan, it is located in the South Area of Qingshui Industrial Park within the Yushen Industrial Park in Yulin City, Shaanxi Province. The project covers an area of 1,365 mu, and it utilizes coal-to-ethanol technology that was jointly developed by Yanchang Petroleum and Dalian Institute of Chemical Physics and for which independent intellectual property rights exist. The project is scheduled to be fully handed over on May 30, 2022. The construction scope includes a methanol complex (units such as coal unloading and storage facilities, gasification units, shift conversion units, purification units, gas separation units, methanol production units, and sulfur treatment units), an ethanol plant (units including dimethyl ether production, carbonylation processes, hydrogenation units, separation systems, compression equipment, heating furnaces, and refrigeration stations), as well as new construction for utility systems and auxiliary facilities; the design capacity is 1.22 million tons of coal to be converted per year. Beijing Petrochemical Engineering Co., Ltd. (Beiyou Engineering) has been assigned a total EPC contract value of 3.78 billion yuan, covering auxiliary facilities and plant-wide system projects, as well as process units and water treatment systems; it is also responsible for providing overall project management services for this initiative. As the EPC general contractor for the gasification unit of this project, Aerospace Engineering Company signed a general contract with Yushen Energy Chemical Company worth 590 million yuan; the project utilizes two 2,000-ton-class aerospace furnaces.
