The T1 tower of the ethylene glycol plant in Yueneng Chemical’s project was successfully lifted into place. Author/Source: Yueneng Chemical. Date: April 16, 2022. Clicks: 14. At 17:30 on the afternoon of April 14, at the construction site of Yueneng Chemical’s ethylene glycol project, the T1 tower of the ethylene glycol plant was successfully installed, marking another significant step forward in the completion of the installation of tower equipment for this plant. The equipment to be lifted this time is Tower T1, with a weight of 362 tons (including insulation and ladder platforms); it is the heaviest piece of equipment to be lifted in the ethylene glycol plant. The diameter of the equipment is 6 meters, and its height is 58.8 meters. This time, a 1,250-ton crane is used as the main crane, and a 650-ton crane is used as the auxiliary crane. The first phase of the project to produce 400,000 tons per year of ethylene glycol as part of Shaanxi Yulin Energy Group Co., Ltd.’s 1.2 million tons per year coal-based ethylene glycol production capacity, is a project that marks the start of operations at the coal-based clean fuel base and high-end chemical materials base located in the Qingshui Industrial Park of the Yushen Industrial Zone. The total planned area for this project is 711 mu, with an estimated investment of 6 billion yuan; the construction period is 30 months, and completion and operation are scheduled for 2022. The project construction includes a gasification unit, a purification unit, an H2/CO separation unit, an ethylene glycol unit, etc. The utility systems and supporting auxiliary facilities include: 3×350t/h high-temperature and high-pressure circulating fluidized bed boilers + 2×30MW back-pressure steam turbine generator sets, air separation units, circulating water stations, desalination stations, storage and transportation facilities, as well as sewage treatment plants. The gasification unit employs the Collin powder gasification technology and includes 2 powder gasifiers; the ethylene glycol unit uses the Zhongke Yuandong ethylene glycol technology. Carbon monoxide and hydrogen are used to indirectly synthesize ethylene glycol through carbonylation, coupling, and hydrogenation, with by-products including dimethyl carbonate, crude ethanol, mixed alcohols, sulfur, liquid oxygen, and liquid nitrogen.
