Jiutai New Materials has successfully initiated the gas supply process, and the ethylene glycol production project has fully entered the preparation phase for operation. Author/Source: Jiutai New Materials Date: May 11, 2022 Clicks: 18 To ensure that the project starts operating by mid-third quarter and that qualified ethylene glycol intermediates can be produced, since May 1st, all teams involved in the project have overcome the challenges posed by pandemic control measures and the need to resume work. They made use of holidays to work overtime continuously in order to speed up the construction progress and prepare for production. Following thorough preliminary preparations, on May 10, the power unit area was successfully ignited and pressurized, marking the official entry of the project with an annual production capacity of 1 million tons of ethylene glycol into the preparatory phase for trial operation; all tasks are progressing in an orderly manner in accordance with the established plan. During the early stage of ignition, the furnace is preheated using stored diesel as fuel; thereafter, fuel coal is delivered from the raw material storage to the boiler, which generates high-pressure steam in a stable manner. This steam is then sent to the methanol production area and the air separation unit to power the respective equipment. Once the project is put into operation as scheduled, it will continue to work on expanding, enhancing, and strengthening the ethylene glycol production chain, thereby laying a solid foundation for the group’s further development of modern coal chemical industry clusters focused on new energy sources and materials such as liquid hydrogen and biodegradable plastics. The integrated project for the production of new types of fine chemicals by Hohhot Xingtai New Materials Technology Co., Ltd. makes full use of the geographical and resource advantages of the Tuoketuo Industrial Park in Hohhot. By leveraging the capital, technical, and talent strengths of the Jutai Group, this project aims to build facilities capable of producing 300,000 tons per year of 1,4-butanediol (BDO), 60,000 tons per year of PBS/PBAT, and 60,000 tons per year of PTMEG. This approach not only aligns with the industrial development policies aimed at promoting new technologies and materials, restructuring the economy, and maintaining growth, but it also helps to optimize the company’s chemical industry chain, increase the added value of its products, and foster the economic development of both the company and the local area. It thus facilitates coordinated development among the company, its resources, the environment, and society. This industrial chain features a high level of technical complexity, which translates into a high added value. By seizing market opportunities and making significant efforts to develop BDO, PBS/PBAT, and PTMEG projects, it is possible to supply products that meet market demand; at the same time, this lays a solid foundation for Jiutai Group to adjust its product portfolio and develop high-value fine chemical products. This project uses calcium carbide as a raw material. Through the calcium carbide-acetylene process, and utilizing the acetylene gas produced by the calcium carbide-acetylene facility, the formalin solution from Jutai’s annual 1 million-ton ethylene glycol production plant, as well as the excess hydrogen generated by AP Company’s gasification facility, it produces 300,000 tons of 1,4-butanediol (BDO). Further downstream processing is carried out to produce biodegradable plastics such as PBS/PBAT and high-end polyether materials like PTMEG, thereby enabling the gasification facility to operate at full capacity and realize its maximum potential. The auxiliary facilities and environmental protection systems for the new plant are all based on Inner Mongolia Jiu Tai New Materials Co., Ltd.’s project for producing 1 million tons of ethylene glycol per year.
