How is the absorption efficiency of various exhaust gas components through spraying, or using water or acids and bases, calculated? Are there any reference materials?

The calculation of the absorption efficiency for various components in exhaust gases, via spraying, water absorption, or acid-base absorption, usually requires taking into account multiple factors such as the exhaust gas flow rate, the concentration values of the components before and after entering the absorber, and the flow rate of the absorbent. The specific calculation methods and parameter settings need to be determined based on actual conditions; one can refer to scientific literature in related fields or the advice of professional consulting agencies. Here are some reference materials that may be useful: – Environmental standards: “Emission Standards for Pollutants” (GB 31570-2015); – U.S. Environmental Protection Agency (EPA)’s “Methods of Testing for Air Emissions Sources” (AP-42); – “Manual on Waste Gas Pollution Control Technologies”, compiled by the Chinese Society for Environmental Sciences and the Chinese Society of Chemical Engineering. Regarding the HOG lookup you mentioned, NOG stands for “Hazardous Organic Gases”, meaning dangerous organic gases. HOG is the abbreviation for “Hazardous Organic Gas,” and it refers to a group of various organic compounds, including benzene, toluene, xylene, vinyl chloride, propylene, and others. The HOG lookup table is a method used to assess the risk of hazardous organic gas leaks that may occur in chemical plants and other production facilities. .
