Contract signed for waste gas compression units in Hami Guanghui ethylene glycol project Author/Source: Huahua Net Coal Chemicals Date: 2019-08-29 Clicks: 59 Recently, SHENGU Group and China Fifth Ring Engineering Co., Ltd. successfully signed a contract for the waste gas compression units in the Hami Guanghui ethylene glycol project. The Hami Guanghui ethylene glycol project produces 400,000 tons per year of ethylene glycol from waste gas. By properly arranging various treatment units in the purification system and continuously adjusting the process parameters, the organic sulfur contained in the waste gas is converted into H2S, which can be easily recovered. Sulfur is then produced through wet sulfur recovery systems, thereby enabling maximum utilization of this waste gas resource. In this way, complex waste gas can be transformed into useful syngas, resulting in a direct reduction of approximately 600,000 tons of CO2 emissions per year, as well as an indirect reduction of around 1.7 million tons of CO2 emissions per year. On June 15, 2019, the EPC general contract for the project to produce 400,000 tons of ethylene glycol per year through the comprehensive utilization of waste gas at Hami Guanghui Environmental Protection Technology Co., Ltd. was signed in Urumqi. The contracting parties are Guanghui Energy Hami Guanghui Environmental Protection Technology Co., Ltd. and China Five Rings Engineering Co., Ltd., which is affiliated with Sinochem. In March 2019, Guanghui Energy and Nanjing Sansheng Logistics Co., Ltd. jointly invested in establishing a holding subsidiary, Hami Guanghui Environmental Protection Technology Co., Ltd., with Guanghui Energy holding 95% of the shares. The total planned investment for this project is 355,980 million yuan, and it will be constructed in the Naomaohu Industrial Park, Yiwu County, Hami Region, Xinjiang. 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 developed by the holding subsidiary Xinjiang Guanghui Coal Clean Refining Co., Ltd., as raw material. Through conversion and gas purification and separation processes, pure carbon monoxide and hydrogen are obtained, which are then used to produce ethylene glycol via the oxalate method. The project is constructed 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 and a total investment of 1.686 billion yuan ； Once the project is put into operation, it will produce products such as 400,000 tons of ethylene glycol.
