On July 26, Shaanxi Yuneng Chemical Materials Co., Ltd. held an industrial extension seminar for the ethylene glycol start-up project. Zhang Jixiao, member of the party committee and deputy general manager of the group company, secretary of the company’s party branch, and chairman of the board, attended and chaired the meeting. Zhang Guangrui, member of the company’s party branch and vice chairman, Wang Wuping, chief engineer, the group’s strategic planning department, production operation department, financial assets department, research institute, Ningbo Zhongke Far East Catalytic Technology Co., Ltd. and relevant company personnel attended the meeting.
At the meeting, Ningbo Zhongke Far East Catalytic Technology Co., Ltd. discussed the extension of the ethylene glycol industry from market potential, market capacity, downstream industry development prospects, Special reports were made on investment benefit analysis and other aspects. Participants had in-depth and extensive exchanges on technologies related to the extension of the ethylene glycol industry. Zhang Jixiao made arrangements for the next stage of the extension of the ethylene glycol industry.
The meeting pointed out that extensive research, in-depth demonstration, careful screening, opening up the upstream and downstream, expanding and extending the industrial chain, and achieving product diversification are the only way for the company to develop and grow.
Zhang Jixiao emphasized that all departments of the company should improve their position and work together to expand the industrial chain, cultivate new industries, achieve product diversification, and improve market competition based on the existing process flow. Break out of the tight encirclement and seek new breakthroughs to lay a solid foundation for the long-term development of the enterprise.
Zhang Jixiao requested that all departments should quickly promote the early establishment of PGA, DMC, chemical logistics parks, overhaul and remanufacturing and other industries.
Project Overview
Shaanxi Yulin Energy Group Co., Ltd. Coal-based 1.2 million tons/year ethylene glycol phase I 400,000 tons /year ethylene glycol start-up project is a start-up project of Yuneng Group Company in the coal-based clean fuel base and high-end chemical materials base in Qingshui Industrial Park, Yushen Industrial Zone. The total planned area is 1,711 acres. The project plans to have the main device basically out of zero meters on June 15, 2021; all devices will be handed over on June 15, 2022; it will be completed and produce qualified products on December 15, 2022. The total project period is 21 and a half months, and the total project investment is controlled Within 5.8 billion yuan.
The first phase of Yulin Energy’s 400,000 tons/year ethylene glycol project uses mixed coal as raw material and uses Colin’s pulverized coal gasification to produce crude syngas. The crude syngas is divided into two streams after conversion. After one stream of crude syngas undergoes heat recovery, it is sent to low-temperature methanol to elute the sulfur and CO2 impurities. The purified syngas is cryogenically separated to obtain the CO product, which is used for ethylene dioxide. The alcohol unit is used, and the hydrogen-rich gas separated by cryogenics is sent to the pressure swing adsorption device to extract H2; the other crude synthesis gas undergoes two-stage isothermal transformation, and is sent to low-temperature methanol to elute the sulfur and CO2 impurities, and then separated from the cryogenics The rich hydrogen gas enters PSA-H2 together to obtain H2 product for use in the ethylene glycol unit.
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 ethylene glycol technology, using CO as raw material, to synthesize dimethyl oxalate (DMO) through oxidative coupling reaction , dimethyl oxalate is then hydrogenated to synthesize ethylene glycol. </p
