Recently, the approval for the revised environmental impact assessment of Jutai Energy (Ordos) Co., Ltd.’s 500,000-ton per year ethylene glycol production project was announced. Overview of the existing project: In January 2015, the Environmental Protection Department of Inner Mongolia Autonomous Region issued the \"Approval on the Environmental Impact Report for Jiu Tai Energy (Ordos) Co., Ltd.’s project to produce 500,000 tons of ethylene glycol per year\" (Nei Huan Shen [2015] No. 7). Jiutai Energy (Ordos) Co., Ltd.’s project for producing 500,000 tons of ethylene glycol per year (hereinafter referred to as the original project) is located in the Coal Chemical Industry Park in Dalu New Area, Zhungeer Banner, Inner Mongolia. It utilizes Texaco’s water-coal slurry gasification technology, and the ethylene glycol is synthesized through a water-coal slurry gasification-dimethyl oxalate process. The plant is equipped with 3 circulating fluidized bed boilers, each with a capacity of 220 tons per hour (2 in operation and 1 as backup). The original project underwent optimization and adjustments during the design phase; the nature and location of the construction have not changed as a result of these changes. However, the design plans for the gasification unit, methanol plant, ethylene glycol plant, as well as those for sewage treatment and the boiler room, have been altered. Overview of the modification project: Utilize pressurized coal gasification and formaldehyde hydrocarbonylation methods to produce 500,000 tons of ethylene glycol per year. The total investment for this project is 6.505 billion yuan, of which 503 million yuan is allocated to environmental protection measures, accounting for 7.73% of the total investment. On July 10, Aerospace Changzheng Chemical Engineering Co., Ltd. issued a special major contract announcement; the type of contract was a general contracting agreement for Jutai Energy (Ordos) Co., Ltd.’s project to produce 500,000 tons of ethylene glycol per year. The contract value is estimated to be 984.95 million yuan. This project uses coal as raw material and employs the aerospace pressurized coal gasification process to produce crude syngas, which is then purified to supply qualified syngas to the client. The nominal capacity of the project is an annual production of 500,000 tons of ethylene glycol. The normal production capacity of syngas is 227,272 Nm3/h (CO+H2), with a maximum gas production capacity at load of 250,000 Nm3/h (CO+H2). Jiutai Energy (Ordos) Co., Ltd. is located in the Dalu New Area of Zhungeer Banner, Ordos City, and is a wholly-owned subsidiary of Jiutai Energy Inner Mongolia Co., Ltd. To effectively promote the deep processing and on-site conversion of coal in the Ordos region, extend the industrial chain, and increase the added value of products, the company obtained approval from the Autonomous Region’s Development and Reform Commission in January 2014 to build a project for the production of 500,000 tons per year of ethylene glycol; this project covers an area of 1,000 mu.
Meeting on the Process Package and Basic Design for Inner Mongolia Jiu Tai New Materials’ Ethylene Glycol Project Held Author/Source: Date: 2018-08-06 Clicks: 30 From August 2 to 3, a meeting regarding the process package and basic design for Inner Mongolia Jiu Tai New Materials Co., Ltd.’s project to produce 1 million tons of ethylene glycol per year was held in Hohhot. The holding of this meeting will provide a data foundation for subsequent preliminary design and detailed design, ensuring the orderly progress of the project construction. The meeting discussed the design criteria for the process packages of various units, the specifications for utility systems, and the schedule for submitting the process packages, and reached a consensus. The plant scale, design basis, design scope of each patent holder, overall layout of various plant areas, boundary conditions of the plant, composition of feed gas and product gas as well as waste gases entering and leaving the plant area, etc., have been determined. President Wang Zhen of Inner Mongolia Jutai New Materials Co., Ltd., General Manager Cui Yijun, General Manager Shao Zelai of Jutai Group’s procurement department, as well as relevant leaders and technical personnel from various design firms attended the meeting. President Wang of Zhen Town demanded that all design firms should further improve the design plans and coordinate and integrate the various components involved in the project, so as to ensure the orderly progress of the overall design. They must adhere strictly to the scheduled deadlines, maintain a clear understanding of the project’s development direction, leverage their expertise, carry out thorough design work, and optimize the design solutions – all in order to provide a scientific basis and essential support for the timely completion and operation of the project. The 1 million-ton per year ethylene glycol production project of Inner Mongolia Jiutai New Materials Co., Ltd. is located in the Tuoketuo Industrial Park of Hohhot Helinger New Area. The project uses coal as raw material, and employs domestically advanced gasification technology for coal to produce syngas, as well as Zongxin Wanfeng Davy’s hydroxymethylation process to manufacture ethylene glycol. In September 2017, the 1 million-ton ethylene glycol project of Inner Mongolia Jiu Tai Group entered into a project engineering design contract with Hualu Technology. The scope includes all process units other than the air separation unit, gasification unit, shift unit, and low-temperature methanol washing unit, as well as utility systems, auxiliary facility works, and the overall project design. On May 21, 2018, the signing ceremony for the technical contract of Inner Mongolia Jutai New Materials Co., Ltd.’s 1 million tons per year coal-based ethylene glycol production project was held at Hualu Engineering Technology Co., Ltd., marking Hualu Technology as the first engineering company in China to collaborate with Johnson Matthey and adopt its ethylene glycol technology.
