The fuel ethanol production line at Ningxia Shoulang Jiyuan New Energy Technology is set to be completed and put into operation by the end of the year. Author/Source: Sinochem News Network; Date: 2020-05-20; Clicks: 3. The first such production line in Ningxia and the second in China, utilizing industrial waste gas containing carbon monoxide (CO) as raw material, is under construction at Ningxia Shoulang Jiyuan New Energy Technology Co., Ltd. The project is currently in the main construction phase, with completion and operation expected by the end of the year. This fuel ethanol production line utilizes the proprietary gas fermentation technology of Beijing Shougang Langze New Energy Technology Co., Ltd. to recycle and treat the exhaust gases from ferroalloy electric arc furnaces; through biological fermentation, carbon monoxide in these exhaust gases is absorbed and converted directly into fuel ethanol. Upon completion, the project will be able to produce 45,000 tons of fuel ethanol per year, along with 5,000 tons of animal protein feed as a by-product, generating an industrial output value of 300 million yuan. Compared with existing methods for utilizing industrial exhaust gases, the economic value of producing fuel ethanol from carbon monoxide is 2.5 to 3 times that of generating electricity through combustion; its energy utilization efficiency is 1.5 to 2 times higher than that method. It can reduce emissions by approximately 170,000 tons of carbon dioxide, 480 tons of nitrogen oxides, and 130 tons of particulate matter each year. It possesses a strong demonstration effect and high potential for widespread adoption, and is of great significance for promoting the comprehensive utilization of exhaust gases from Ningxia’s metallurgical industry. In 2019, Ningxia’s ferroalloy production amounted to 3.774 million tons, accounting for about 10% of the country’s total production. It generated approximately 3 billion cubic meters of exhaust gas per year, with an apparent annual consumption of gasoline of around 2 million tons. According to calculations, if 50% of the exhaust gases from ferroalloy and silicon carbide electric arc furnaces are efficiently cleaned and utilized through biological fermentation technology, approximately 200,000 tons of fuel ethanol can be produced annually. This amount would not only meet the region’s demand for ethanol-based gasoline (E10) but also allow for the production of chemical products such as 2,3-butanediol, isopropanol, and 1,3-butadiene, offering broad market prospects.
