The first large-scale equipment for the 400,000 tons per year ethylene glycol production project using waste gas from Hami Guanghui Environmental Protection Technology Co., Ltd. was successfully lifted into place in one go. Author/Source: Sinochem News Network; Date: July 15, 2020; Clicks: 4. On the morning of July 13, the first large-scale equipment for this project – the conversion furnace – was successfully lifted and installed in one attempt, thanks to the EPC contracting by China Fifth Ring Engineering Co., Ltd. and the construction work carried out by China Chemical Engineering 11th Construction Co., Ltd. The converter to be lifted this time has the equipment code R04201A; it has a diameter of 3.8 meters and a height of 19.6 meters, with a net weight of 145 tons. It is a key piece of equipment for Hami Guanghui’s 400,000 tons per year ethylene glycol production project using waste gas. It is reported that the project of Hami Guanghui Environmental Protection Technology Co., Ltd., which aims to produce 400,000 tons of ethylene glycol per year through the comprehensive utilization of waste gas, is the first energy utilization project in China to use waste gas resources for the production of ethylene glycol. Located in the Naomaohu Industrial Park in Yiwu County, Hami City, Xinjiang, the project has a total investment of 3.56 billion yuan, and its EPC work was carried out by China Wuhuan Engineering Corporation. The Guanghui ethylene glycol project was built in two phases: Phase 1 has a capacity of 200,000 tons, with a total investment of 1.87 billion yuan, while Phase 2 also has a capacity of 200,000 tons, requiring a total investment of 1.686 billion yuan. The project uses the waste gas generated as a by-product of the 10 million tons per year coal grading, upgrading, and comprehensive utilization project, which was constructed by the holding subsidiary Xinjiang Guanghui Coal Clean Refining Co., Ltd., as its raw material. It employs the third-generation technology for \"producing polyester-grade ethylene glycol from WHB syngas\", jointly developed by Wuhuan, Huashuo, and Hebi Bama. Through a series of processes including conversion, reforming, low-temperature methanol washing, and PSA adsorption separation, the valuable syngas components H2 and CO present in the waste gas are extracted, and high-end chemical products—polyester-grade ethylene glycol—are produced using carbonylation, hydrogenation, and purification technologies.
