What are the sources, classifications, and characteristics of chemical industry waste gases?

Source: 1. Exhaust gases from fuel combustion. 2. Waste gases from industrial production sources (coal, oil, natural gas, steel, non-ferrous metals, construction, chemical industry). Category: 1. Particulate pollutants. 2. Gaseous pollutants (sulfur compounds, nitrogen compounds, carbon oxides, hydrocarbons, halogen-containing mixtures). 3. Radioactive pollutants.

To explain the types of chemical enterprises, different types of waste gases exist!

Source: Waste gas generated by side reactions and incomplete chemical reactions； Waste gases generated during the processing and use of products, as well as dust produced during handling, crushing, screening, and packaging processes ； The outdated production technology and equipment lead to incomplete reactions and unstable production processes, resulting in defective products or issues such as material leakage, spills, and losses” ； Emission of waste gases due to starting and stopping operations, or as a result of operational errors, improper instructions, or poor management ； Certain gases emitted in chemical manufacturing can undergo chemical reactions under the influence of light or rain, thereby producing harmful gases as well. Classification: Based on the nature of the pollutants contained, they can be divided into three main categories: chemical waste gases containing inorganic pollutants ； Organic waste gas ； Waste gas that contains both organic and inorganic substances. Features: A wide variety of types ； It has a complex composition and is somewhat toxic ； High pollutant concentration ； Wide range of contamination, high level of hazard ； Waste gas pollutants are difficult to treat.
