Contract for air separation unit signed for 300,000-ton coal-based ethylene glycol project at Shanxi Weihua Binzhou Chemical Industry Company / Author/Source: Huahua Network – Coal Chemicals / Date: 2018-02-11 / Views: 39. Recently, Shanghai Baosteel Gas Co., Ltd. signed an industrial gas supply contract with Shanxi Coal Group Weihua Binzhou Chemical Industry Co., Ltd., to supply products such as oxygen, nitrogen, and instrument air for its project aimed at producing 300,000 tons of coal-based ethylene glycol per year. It is reported that Baosteel Gas will establish an independent corporate project company, which will invest in the construction and operation of an air separation unit with a capacity of 60,000 cubic meters per hour. The project company will obtain steam and electricity supply from Weihua Binzhou Chemical, and will supply gas products to this company under an industrial gas supply contract. The air separation unit is expected to come online in 2019. This cooperation with Shaanxi Coal Group marks the first time that Baosteel Gas has supplied industrial gas products for an independent, large-scale coal-based ethylene glycol project. The air separation unit to be built will, together with the already operational Shaanxi Baosteel Gas and Shaanxi Clean Energy facilities, create a regional competitive advantage. Shaanxi Coal Group is the leading enterprise in the development and construction of coal bases as well as in the energy and chemical industries in Shaanxi Province. Its subsidiary, WeiHua Group, is a pioneer in the development of modern coal chemical industry in China and in the application of new-generation coal gasification technologies. The 300,000-ton-per-year coal-based ethylene glycol production project developed by Weihua Binzhou Chemical Construction is one of the two key coal-based ethylene glycol projects under construction in Shaanxi Province. The project 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 Gaoxuehua 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 fractions per year, 5,920 tons of fusel oil per year, 13,440 tons of light fractions per year, 6,048 tons of heavy ethylene glycol fractions 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.
