Commencement of civil work for the power station in Yushen Energy Chemical’s coal-based ethanol project of Yan’an Petroleum / Source: Chemical Industry Network, Coal Chemicals Section. Date: July 14, 2020. Clicks: 11. On the morning of July 13, a ceremony marking the start of the civil work for the power station was held at the construction site of Yushen Energy Chemical’s 500,000-ton/year coal-based ethanol project in Shaanxi, signaling the full commencement of this civil work. The main equipment of the power station system includes boilers, continuous and periodic blowdown expanders, deaerators, boiler feed water pumps, back-pressure steam turbines, temperature and pressure reducers, etc. The system is equipped with 3 high-temperature and high-pressure circulating fluidized bed boilers with a capacity of 260 t/h each, as well as 1 25 MW back-pressure steam turbine generator set, which ensure the satisfaction of the needs of the chemical processing units under various operating conditions. The foundation of the power station is constructed using concrete cast-in-place piles; a total of 780 such piles are to be used. The pouring of these piles is expected to be completed in 20 days, while the strength testing will be finished in 50 days. On the morning of July 8, construction began on the first pouring pile of the carbonylation framework, which is the core component of the project’s ethanol plant, marking the full commencement of civil work for the ethanol plant. On June 27th and 28th, construction began on the plant’s main substation as well as the building structures throughout the facility. On June 12, the construction of the ethanol finished product tank area and Pump Station (1) for Bid Section 1 commenced, marking the official start of the project. In 2020, Yushen Energy & Chemical will make every effort to advance the construction of the ethanol project by focusing on three \"completions\", two \"50% targets\" and one \"start“. The three \"completions\" refer to completing the annual investment of 1.18 billion yuan in the project, finalizing the EPC contract for the ethanol project, and completing the procurement of long-term-use equipment ； The two “50%” refer to completing 50% of the detailed design and 50% of the civil construction work ； A “Start” means beginning the device installation. On June 2, the signing ceremony for the EPC general contract of Yushen Energy and Chemical Co., Ltd. of Yanjiang Petroleum’s 500,000 tons per year coal-based ethanol project was held in Xi’an. Li Junlin, executive director of Yushen Nenghua Company, signed EPC general contract agreements for the ethanol project with Beijing Petrochemical Engineering Company and China Aerospace Changzheng Engineering Company respectively. Beijing Petrochemical Engineering Co., Ltd., a subsidiary of Shaanxi Construction Group, won two bidding packages worth a total of 3.78 billion yuan. The EPC general contracting for bid sections 1 and 2 of this project involves public auxiliary equipment and plant-wide system engineering, as well as process equipment and water treatment systems. As the EPC general contractor for the gasification unit of this project, the Aerospace Engineering Company signed a general contract with Yushen Energy Chemical Company, with a contract value of 590 million yuan. The project uses 2 2,000-ton-class space furnaces. The 500,000 tons per year coal-based ethanol project of Yanchang Petroleum in Yushen utilizes the dimethyl ether carbonylation technology for ethanol production, which was developed jointly by Yanchang Petroleum and the Dalian Institute of Chemical Physics of the Chinese Academy of Sciences, to produce 500,000 tons of ethanol annually. The project requires an investment of 6.98 billion yuan; it is located in the South Area of Qingshui Industrial Park, Yushen Industrial Park, Yulin City, Shaanxi Province, covering an area of 1,365 mu. Completion is scheduled for mid-2021, with full operation and compliance with standards to be achieved by 2022. The construction scope includes a methanol complex (devices such as coal unloading and storage, gasification unit, shift converter unit, purification unit, gas separation unit, methanol production unit, sulfur treatment unit, etc.), an ethanol plant (units such as dimethyl ether production, carbonylation, hydrogenation, separation, compression, heating furnaces, refrigeration stations, etc.), as well as new constructions for utility systems and auxiliary facilities, with a designed capacity to convert 1.22 million tons of coal per year.
