Design coordination meeting for Shaanxi Yanchang Petroleum Yushen Energy Chemical’s 500,000 tons/year coal-based ethanol project held / Author/Source: Coal Chemical Industry 114 Forum / Date: May 27, 2020 / Clicks: 7. On May 25, the kick-off meeting for the circulating fluidized bed boiler and steam turbine generator set of Shaanxi Yanchang Petroleum Yushen Energy Chemical Co., Ltd.’s 500,000 tons/year coal-based ethanol project, along with the first design coordination meeting, was held in Chengdu. Liao Xin, assistant to the general manager of Dongfang Boiler Co., Ltd. under Dongfang Electric Group, Gao Yihan, project manager and design manager of the power station at Beijing Petrochemical Engineering Co., Ltd., Zhang Xiaodong, deputy general manager of the company, and relevant technical staff attended the meeting. The meeting provided a detailed report on the preliminary preparations for the project, task allocation, and implementation plan. Discussions, consultations, and confirmations were held regarding the preliminary design concepts for the three main boiler units, the conditions required to meet those preliminary design requirements, the schedule for delivering boiler design documents, as well as the channels for transmitting documents and information. Full communication and coordination were carried out regarding issues such as supply to host device manufacturers, design interfaces, and the list of required funds, and an agreement was ultimately reached. The successful holding of this meeting marks another significant step forward in the production and supply of the three main boiler equipment units, as well as in the design of the related process systems by Yushen Company. It provides a solid foundation for subsequent work such as the design of construction drawings, project construction, and equipment supply. The 500,000 tons per year coal-based ethanol project of Shaanxi Yanchang Petroleum Yushen Energy Chemical Co., Ltd. has a total investment of 6.98 billion yuan and covers an area of 1,365 mu. It utilizes Yanchang Petroleum’s own dimethyl ether carbonylation technology to produce ethanol at a rate of 500,000 tons per year, with the goal of completing the project by the end of 2021. This project is a key coal chemical project planned by Shaanxi Yanchang Petroleum Group during the 13th Five-Year Plan period; the preliminary feasibility study for its own power station proposes the use of 3×260-ton/hour high-temperature and high-pressure coal powder boilers. The Yushen Nenghua 500,000 tons/year coal-based ethanol project is an expanded version of the world’s first industrial-scale project for producing ethanol from syngas at a capacity of 100,000 tons per year. This project was developed using proprietary technology owned by the Dalian Institute of Chemical Physics, Chinese Academy of Sciences, in collaboration with Shaanxi Yanchang Petroleum (Group) Co., Ltd. This project uses the Xiguan open-pit coal mine as its raw material, and employs the HT-L gasification technology to produce raw gas. One stream of this raw gas undergoes conversion, while another stream is used for waste heat recovery. Both streams are then subjected to low-temperature methanol washing to remove sulfur and carbon dioxide from them. The gas that has not undergone conversion is purified and separated into H2 and CO through deep cooling; part of the gas that has undergone conversion is sent to a PSA unit for hydrogen production, and another part is sent to a methanol synthesis unit to produce methanol. CO, H2, and methanol are then sent to an ethanol production facility.
