It is reported that the main device engineering of the 400,000-ton ethylene glycol project The PC project is divided into three bid sections: A, B, and C. Among them, the general contractor for the construction of section A is China Chemical Engineering No. 14 Construction Co., Ltd. The project content includes the procurement and procurement of air separation units, gasification units, purification units, entire off-site pipe corridors, central control rooms, and all-site fire protection. Construction and installation work.
The general contractor for the construction of section B is Northwest Electric Power Construction No. 1 Engineering Co., Ltd., and the project content is the procurement and construction of thermal power stations.
The general contractor for the construction of section C is Shaanxi Construction Engineering and Installation Group Co., Ltd. The project includes the procurement and construction of ethylene glycol devices, tank farms and other public systems.
The project plans to fully commence construction on March 1, 2021; the foundation of the main device will be zero meters on June 15, 2021; and the handover of all devices will be completed on June 15, 2022; It will be completed and produce qualified products on December 15, 2022. The total project period will be 21 and a half months, and the total project investment will be controlled within 5.8 billion yuan.
Overview of the 400,000-ton ethylene glycol project
Shaanxi Yuneng Chemical Materials Co., Ltd.’s coal-to-produce 1.2 million tons/year ethylene glycol phase I 400,000 tons/year ethylene glycol start-up project is a coal-to-clean fuel base of Yuneng Group Company in Qingshui Industrial Park, Yushen Industrial Zone and a start-up project of a high-end chemical materials base, with a total planned area of 1,711 acres. The project is expected to invest 6.243 billion yuan, and the environmental protection investment is 532.6274 million yuan. The construction period is 30 months. It is planned to be completed and put into operation in June 2022.
The project adopts production processes such as coal-to-syngas. Carbon monoxide and hydrogen are indirectly synthesized into ethylene glycol through carbonylation, coupling, and hydrogenation, and dimethyl carbonate and crude oil are co-produced. Products such as ethanol, mixed alcohols, sulfur, liquid oxygen, liquid nitrogen, etc. The main equipment includes coal-to-syngas, purification and separation, ethylene glycol synthesis, boiler thermoelectricity, air separation units and supporting public works.
The project construction content includes coal gasification equipment, purification equipment, H2/CO separation equipment, ethylene glycol equipment, etc. Public works and supporting auxiliary facilities include: 3×350t/h high-temperature and high-pressure circulating fluidized bed boiler + 2×30MW pump-back steam turbine generator unit, air separation unit, circulating water station, desalted water station, storage and transportation facilities, and sewage treatment Stand and wait. The coal gasification unit adopts Colin’s pulverized coal gasification technology, including 2 pulverized coal gasifiers; the ethylene glycol unit adopts Zhongke Far East’s ethylene glycol technology. </p
