[Haichuan Chemical Salary News] Launch Ceremony for Boiler Ignition at the 300,000-ton/year coal-based ethylene glycol project in Binzhou, Weihe River, held on May 30

Project Overview: The 300,000 tons per year coal-to-ethylene glycol plant in Binzhou, Weihe River, uses GE water-coal slurry gasification to produce H2 and CO gases through conversion, purification, and gas separation. High Chemical Co., Ltd. employs an oxalate-based method for the production of ethylene glycol, with sulfur as a by-product. The overall design institute is Donghua Engineering Company. Upon completion of the project, it will produce 300,000 tons of ethylene glycol per year. The by-products will include 17,576 tons of crude DMC per year, 5,336 tons of DMO Reconstituted components per year, 5,920 tons of fusel oil per year, 13,440 tons of light fractions per year, 6,048 tons of heavy fractions of ethylene glycol per year, and 4,321.6 tons of sulfur per year. The total investment for the project is 5.495 billion yuan, of which 444 million yuan is allocated to environmental protection measures. (Source: Binzhou News)

On the morning of March 20, Weihua Company and Baoji Huahai Industry and Trade Co., Ltd. held a signing ceremony in Xi’an regarding the transportation agreement for 300,000 tons of ethylene glycol produced by Weihua Binzhou Company. At present, the ethylene glycol project of Binzhou Company under Weihua Group is under active construction, and it is expected to be completed and put into operation in October this year. Weihua Company took proactive measures; while accelerating the construction of its projects, it planned in advance for the sales of ethylene glycol products. It held numerous discussions with Baoji Huahai Industry and Trade Co., Ltd. regarding the transportation of these products, to ensure a safe and reliable door-to-door logistics service that combined road and rail transport. To ensure the delivery of 300,000 tons of ethylene glycol, Huahai Company established a specialized department for this task. It rented a 2,250-square-meter container yard at Binzhou West Station, and received approval from Shaanxi Coal Group for the procurement of containers. Weihua Group and Huahai Company are both key enterprises under Shaanxi Coal Group. The two companies have maintained long-term cooperation in areas such as coal and methanol transportation, building a strong friendship over time. Through this renewed cooperation in the transportation of ethylene glycol products, the two parties working together will make a positive contribution to the export transportation of the products produced by the Weihua Binzhou Company’s project once it goes into operation.

At the construction site of Shaanxi Coal Weihua Group’s 300,000 tons per year coal-to-ethylene glycol project, reporters saw that work had resumed on a full scale there; the normal supply of natural gas had been established, the boilers had been started up, and construction work was also underway in the air separation, gasification, and synthesis units. Although the project was delayed by about 2 months due to the pandemic, measures such as increasing the workforce, improving equipment efficiency, and optimizing construction methods were taken to ensure that the project is completed on schedule. It is expected that boiler ignition will take place by May 30 this year, while chemical feeding and trial operation will be completed by November of this year. In terms of epidemic prevention and control, the project site implements protective measures such as entry/exit registration, disinfection, and temperature checks; designated isolation areas are set up for workers returning to Bin. It is said that ethylene glycol is primarily used in the synthesis of polyester products; it can also be used as a lubricant and in the production of synthetic resin PET. PET in the form of bottle-grade material is the main raw material used for manufacturing clothing and sportswear. Yang Ye, Zhou Jie)

December 13, 2019: To date, the gasification unit has had 28 pumps and 90 static equipment units installed. 704’s wastewater treatment section has 45% of the total piping work completed, while 705’s conversion section has 30% of the total work completed. Currently, the materials for the custom-made equipment produced on-site are arriving one after another, and manufacturing has already begun. The overall framework of the coal grinder plant was completed in September, the roof was installed in November, and the construction workers are currently bricklaying the openings for doors and windows. To ensure that the flare emission system for the key facilities across the plant is put into use as soon as possible, the gasification project team has arranged tasks on a daily basis based on the actual conditions at the construction site, advancing work on the excavation of the flare foundation to create favorable conditions for installing the 95-meter-tall flare tower next year. Earlier on, the project team conducted a thorough inspection of the plant area. Pay special attention to sealing the openings in the pipes and the inlets and outlets of the equipment properly. The rotating equipment should be turned over once a week on schedule. Drain all water from the heat exchangers and storage tanks one by one. Pits, cup-shaped foundations, and equipment foundations that have not undergone secondary grouting are prone to freezing, which can weaken the strength of these foundations. The project team has communicated several times with Thirteenth Construction Company; for those foundations that meet the conditions for pouring concrete, it is necessary to contact the concrete mixing plant immediately to arrange for concrete pouring. Otherwise, those foundations should be sealed tightly to ensure safety. As December arrives, project construction also enters winter mode.
