Lifting of the air separation distillation tower for Inner Mongolia Jutai New Materials Company’s 1 million-ton coal-to-ethylene glycol project begins / Author/Source: Huahua Network – Coal Chemicals / Date: 2019-08-26 / Clicks: 13 On August 21, the lifting of the air separation distillation tower for the syngas island of Inner Mongolia Jutai New Materials Company’s 1 million-ton coal-to-ethylene glycol project, carried out by Air Products and Chemicals (China) Investment Co., Ltd., began; the process was completed successfully in about 3 hours, with the lifting of the two-stage distillation towers in the cold box being finished. The air separation unit for the new material company’s project to produce 1 million tons of ethylene glycol per year utilizes air separation technology from the American company AP; the capacity of each series is 100,000 m3/h. The successful installation of the distillation towers marks the entry of the air separation cryogenic tank into the equipment installation phase, which is a milestone for the project’s construction. From August 19 to 24, technical personnel from Inner Mongolia JiuTai New Materials Company, together with those from Formox AB and Hualu Design Institute, held a meeting in Sweden to review the detailed design process packages for the ethylene glycol formaldehyde plant, laying a solid foundation for the subsequent detailed design of this plant. On August 21, the large slab beam of Boiler No. 1 for the boiler island of Inner Mongolia Jutai New Materials Company’s 1-million-ton coal-to-ethylene glycol project, which was under the general contract of Southwest Electric Power Design Institute and constructed by Northwest Electric Power Construction, was successfully lifted into place. As one of the key stages in boiler installation, the installation of the large boiler girders is a challenging task that requires high technical expertise. There are a total of 4 large beam components for the boiler; the one being lifted this time is K2, with a length of 20 meters, a height of 3.35 meters, and a weight of 29.79 tons. It was lifted into place using a 180-ton crawler crane and a 16-ton boom crane, thereby laying a solid foundation for the subsequent installation of the boiler’s heating surfaces. 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 coal gasification and Shell’s gasification technologies, low-temperature methanol washing technology, as well as the world-leading formaldehyde hydroxycarboxylation technology developed by Davy Company to produce ethylene glycol. Among them, Air Products and Chemicals Inc. of the United States 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 producing 1.7 million tons of coal-based olefins and related fine products per year to producing 1 million tons of ethylene glycol per year.
