At 15:00 on January 4, 2021, the coal-water slurry pressurized gasifier of the 300,000 tons/year coal-to-ethylene glycol project of Shaanxi Weihe Binzhou Chemical Co., Ltd. was successfully put into operation at one time, which marked the full entry of the project Open up links in the chemical process.
Binzhou Mayor Wang Hongzhi and the enterprise test team witnessed this important moment. Duan Libo, deputy general manager of the company, guided the drive and introduced the process flow and production operation management ideas to Wang Hongzhi. Chen Peng, deputy chief engineer of Hualu Engineering Design Institute, and the full technical bodyguard of Air Chemical Products Shenhua (Shanghai) Gasification Technology Co., Ltd., a gasification process patent holder.
This is the first chemical feeding after the completion of project construction. The gas production workshop organized chemical feeding related equipment one week before the feeding. , instrumentation, electrical and other majors jointly simulated material input, run-in the team, check for leaks and fill in the gaps. A test run mobilization meeting was held the night before the materials were put in. At the mobilization meeting, everyone repeatedly discussed important operating steps, implemented the test run materials, and assigned relevant operational responsibilities to each person for precise control. This chemical input is a reaction of coal-water slurry and high-pressure oxygen at 1300°C. Considering the safety of personnel, the workshop temporarily closed the test site.
According to experience, the original feeding is half load. At present, the process personnel have completed the pressure boosting work after feeding and eliminated leakage. And the heat tightening work is all done.
Weihua Binzhou Company’s 300,000 tons of ethylene glycol are gasified with GE coal-water slurry. After transformation, purification, The gas is separated to obtain H2 and CO gas, using the ethylene glycol synthesis technology of Kochem Co., Ltd. Delivered in November 2020.
Shaanxi Weihe Binzhou Chemical Co., Ltd. 300,000 tons/year coal-to-ethylene glycol project
Shaanxi Coal Chemical Weihua Group Shaanxi Weihe Binzhou Chemical Co., Ltd. 300,000 tons/year coal-to-ethylene glycol project, It is the earliest coal-to-ethylene glycol project established in Shaanxi Province and plays a leading role in Shaanxi, a major coal-producing province. The project construction site is located in Xinminyuan Modern Coal Chemical Industrial Park, Bin County, and the project covers an area of 600,000 square meters. In April 2016, Shaanxi Weihe Binzhou Chemical Co., Ltd. signed a CTEG technology licensing contract and engineering design contract for the 300,000 tons/year coal-to-ethylene glycol project with Gaochem and Donghua Engineering. The original owner of the project is Shaanxi Binchang Mining Group Co., Ltd. On November 19, 2014, the 300,000-ton coal-to-ethylene glycol project of Binchang Mining Group was officially handed over to Shaanxi Weihe Coal Chemical Group Co., Ltd.
The project construction content includes main projects such as gasification equipment, purification equipment, and ethylene glycol synthesis equipment, as well as public supporting facilities such as water supply and drainage, desalted water stations, power supply, heating, and fire protection. , storage and transportation projects and environmental protection projects such as waste gas treatment, wastewater treatment, and solid waste disposal. After the completion of the project, the annual output of ethylene glycol will be 300,000 tons. By-products: crude DMC 17,576 tons/year, DMO heavy components 5,336 tons/year, fusel oil 5,920 tons/year, the light fraction is 13,440 tons/year, the ethylene glycol heavy fraction is 6,048 tons/year, and the sulfur is 4,321.6 tons/year. The total project investment is 5.495 billion yuan, of which 444 million yuan is environmental protection investment. It is expected to be fully completed and put into pre-production by the end of this year. </p
