[Ten years of major development in chemical technology] 128-2018 The world’s largest 300,000-ton wet acid-making device

Thread Content

Chemical science and technology has developed greatly in the past ten years, praising the prosperity and strength of China. It is more lively and more exciting with everyone's participation. Everyone is welcome to participate in the forum to exchange and discuss. July fires, pay attention to fire prevention------------------------------------------------- On February 3, 2018, Huizhou Hongrui Environmental Protection Energy Co., Ltd., a subsidiary of Bailihong Chemical Group, successfully put into operation a 300,000-ton wet acid-making device per year. The Hongrui project is a supporting project of CNOOC Phase II. It is used to treat the refining waste gas generated by the 10 million tons/year refining of the Hui Refining Phase II. It adopts the world's advanced WSA wet sulfuric acid production process and the domestic advanced ammonia desulfurization tail gas treatment process. It treats approximately 131,000 tons of refining waste gas annually and has an annual output concentration of 300,000 tons of 98% sulfuric acid. It is the largest wet acid production unit currently in production in the world. This project is an environmental protection project that turns waste into treasure, saves energy and reduces emissions. The WSA process has low energy consumption, a sulfur recovery rate of over 99.9%, and waste heat recovery, which can reduce carbon dioxide emissions by 220,000 tons per year. At the same time, the device can achieve lower SO2 emissions and can reach less than 50% of the indicators specified by the traditional sulfuric acid industry. * * The development concept of circular economy.
