On November 26, under the guidance of the expert group of the Provincial Petrochemical Quality Supervision Station, Shaanxi Coal Chemical Weihua Group Shaanxi Weihe Binzhou Chemical Co., Ltd. 300,000 tons/year coal-to-ethylene glycol project gasification workshop gasification positions The purification project manager signed the device delivery documents with the construction unit respectively, which marked the successful conclusion of the gasification and purification project construction. At this point, the gasification furnace feed is on the “fast lane.”
This CCCC project includes the pulping section, gasification section, gray water treatment section, conversion section, low-temperature methanol washing section, cryogenic The separation section, PSA hydrogen production section, sulfur recovery section, 672 compression section, etc. are respectively important production devices in the gas production workshop.
After more than two years of hard work, the two sets of gasification and purification devices have been mechanically completed. In the early stage, after inspecting the process data of the construction unit and putting forward suggestions for rectification, and repeatedly organizing the three inspections and four determinations of the equipment and eliminating deficiencies with the construction unit, supervision unit and Binzhou Company, on November 26, the Provincial Petrochemical Quality Supervision Station After checking the documents submitted during construction and on-site inspection, under the witness of the design unit, supervision unit, etc., the gas production workshop equipment successfully completed the intermediate handover.
On the day of the intermediate handover, most of the devices in the gas production workshop have completed the pre-commissioning work, the finishing work before feeding the gasifier has been completed, and the workshop technicians and instrument professionals have completed the simulation before feeding the gasifier. test. At present, the gasifier can be fed with the necessary raw materials such as oxygen and nitrogen.
The 300,000 tons/year coal-to-ethylene glycol project of Shaanxi Weihe Binzhou Chemical Co., Ltd. of Shaanxi Coal Chemical Weihua Group is the earliest coal-to-ethylene glycol project established in Shaanxi Province. It is for the coal-producing provinces Shaanxi plays a leading and exemplary role. 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, public supporting facilities such as water supply and drainage, desalted water stations, power supply, heating, and fire protection, storage and transportation projects, and waste gas Treatment, wastewater treatment, solid waste disposal and other environmental protection projects. After the project is completed, the annual output of ethylene glycol will be 300,000 tons. By-products: crude DMC 17,576 tons/year, DMO heavy component 5,336 tons/year, fusel oil 5,920 tons/year, light fractions 13,440 tons/year, ethylene glycol heavy fraction 6,048 tons/year, and sulfur 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
