Review Meeting for the Process Package of the Formaldehyde Unit in Inner Mongolia Jiu Tai New Materials Company’s 1 million tons per year coal-based ethylene glycol project held / Author/Source: Chemical Industry Network – Coal Chemicals / Date: 2019-05-27 / Views: 15. From May 20 to 22, a review meeting for the process package of the formaldehyde unit in Inner Mongolia Jiu Tai New Materials Company’s 1 million tons per year coal-based ethylene glycol project was held at Hualu Design Institute; the meeting was aimed at discussing the issues present in the first batch of documents related to the process package for this unit. The formaldehyde unit, serving as the starting point for the ethylene glycol plant, is an important milestone in the construction of ethylene glycol projects. The holding of this review meeting provided technical and data support for the subsequent engineering design. Cao Yingfang, assistant to the general manager of Inner Mongolia Jiu Tai New Materials Company, Shan Xiuli, chief engineer of Hualu Design Institute, Nilspetter Sandén, project manager of JM Formox, and other technical personnel attended the meeting. On May 12, the foundation earthwork work began on the methanol synthesis unit of Jiutai New Materials’ 1 million-ton coal-based ethylene glycol project. The methanol synthesis plant covers an area of 76 mu and employs the methanol synthesis technology developed by Zinnia Davy of the UK; it features advanced technology, a high degree of automation, and strong safety features. On May 9, the construction of the warehouse in the sulfur recovery unit area of Jutai New Materials’ coal-based ethylene glycol project commenced successfully, marking the start of construction work in that area. The sulfur recovery unit is an environmental protection device in the ethylene glycol production system. It was constructed by China National Chemical Engineering 11th Construction Co., Ltd., utilizing the advanced sulfur recovery technology developed by Shandong Sanwei Company. Thanks to its sophisticated design and high reliability, it is expected to be capable of producing 86 tons of sulfur per day. The 1 million-ton per year ethylene glycol production project of Inner Mongolia Joutai New Materials Co., Ltd. is located in the Tuoketuo Industrial Park in Hohhot. With a total investment of 13.3 billion yuan, the project uses aerospace-based coal gasification and Shell’s gasification technologies, low-temperature methanol washing technology, as well as the world-leading formaldehyde hydroxymethylation technology developed by Davy Company to produce ethylene glycol. Among them, Air Products Company of the United States (AP Company) invested 4.8 billion yuan to construct the air separation and gasification areas. The project construction period is 3 years, with trials scheduled for 2020 and full operation to commence in 2021. In June 2017, the plan for the project with an annual production capacity of 1 million tons of ethylene glycol was revised; it was changed from \"an annual production of 1.7 million tons of coal-based olefins and related specialty products\" to \"an annual production of 1 million tons of ethylene glycol\".
