Full commencement of civil work for Yanchang Petroleum Yushen Energy Chemical’s coal-based ethanol project / Author/Source: Huahua Network, Coal Chemicals Industry; Date: July 10, 2020; Clicks: 8. On the morning of July 8, construction began on the first poured pile of the carbonylation framework, which constitutes the core structure of the ethanol production unit in Yanchang Petroleum Yushen Energy Chemical’s 500,000-ton/year coal-based ethanol project – a project that is under EPC management by Beijing Petrochemical Engineering Co., Ltd. This marks the full start of civil work for the ethanol production unit. It is reported that 197 piles need to be driven for the ethanol plant, located in key areas such as the plant’s core dimethyl ether framework, carbonylation framework, hydrogenation and product separation frameworks, as well as the core column vessels; all pile-driving work is scheduled to be completed this month. From July 7th to 8th, a 30% scale model review meeting was held in Xi’an for the sulfur unit of Yushen Energy Chemical Co., Ltd.’s 500,000 tons per year coal-based ethanol project. It is reported that the 30% model review is an important milestone in the project. The sulfur unit project team of Beijing Petrochemical Engineering Co., Ltd. presented a report to the client regarding process flow requirements, equipment layout, pipeline network arrangement, operating space, and maintenance access, and discussed the questions and suggestions raised by the client. Next, the project team will continue to refine the design based on the review suggestions to ensure the smooth progress 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 Yanchang 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, enabling an annual output of 500,000 tons of ethanol. 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 achieved by 2022. The construction scope includes a methanol complex (devices such as coal unloading and storage facilities, gasification units, shift reactors, 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.
