Latest Progress on Weihua Group’s 300,000-ton Coal-to-Ethylene Glycol Project Author/Source: Coal Chemical Industry 114 Forum Date: October 14, 2019 Clicks: 48 On the afternoon of October 10, Zhang Zhengquan, deputy chief engineer of Weihua Group and deputy project director for the ethylene glycol project, along with Liang Xugun, accompanied by workshop leaders and project managers from various construction units, conducted a comprehensive on-site inspection of the ethylene glycol project construction. The comprehensive on-site inspection involves a thorough examination of the construction progress and quality of each construction unit present at the site. The key aspects of this inspection include specific solutions for backfilling soil within designated areas, assessments of the construction quality of each unit, the status of rectifying issues identified before the holiday, as well as the coordination among personnel. During the inspection, the plumbing work in the No. 14 Construction Pump House has been completed; efforts are being made to accelerate the greening works in order to proceed with the next phase of construction plans. In the power area, discussions and arrangements were made with the person in charge of excavation, backfilling, and construction; immediate on-site corrections were carried out for the welding quality issues identified in the welding areas. After inspecting the project site, Zhang Zhengquan provided a summary of this comprehensive inspection. The plan for the internal use of soil has been finalized, and it must be implemented promptly without delay, to avoid affecting the project timeline. The construction site for the 300,000 tons per year coal-based ethylene glycol production facility of Shaanxi Weihe Binzhou Chemical Co., Ltd., which belongs to the Shaanxi Coal Chemical Weihe Group, is located within the Xinminyuan Modern Coal Chemical Industrial Park in Bin County, covering an area of 600,000 square meters. In April 2016, Shaanxi Weihe Binzhou Chemical Co., Ltd. signed a CTEG technology licensing agreement and an engineering design contract for a 300,000 tons per year coal-based ethylene glycol project with Gaoxuehui and Donghua Engineering. The original owner of the project was 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 transferred to Shaanxi Weihe Coal Chemical Group Co., Ltd. The project construction includes the main facilities such as gasification units, purification units, and ethylene glycol synthesis units, as well as auxiliary facilities for water supply and drainage, desalination stations, power supply, heating, and fire protection. It also encompasses storage and transportation systems, as well as environmental protection measures such as waste gas treatment, wastewater treatment, and solid waste disposal. Upon completion, the project will have an annual production capacity of 300,000 tons of ethylene glycol; 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.
