Sodium acetate production project containing acetic acid water steam exhaust gas discharge standard
Sodium acetate production project containing acetic acid water steam exhaust gas discharge standard program
A colorless tasteless crystalline substance of sodium acetate that can be weathered and combustible in air. Soluble in water, slightly soluble in ethanol, insoluble in ether. Lose crystalline water at 123. But usually obtained by wet process with the flavour of acetic acid. Hydrolysis occurs in water.
Therefore, sodium acetate is an organic substance. Organic compounds refer to carbon containing compounds, but remove CO, CO2, H2CO3, and carbonates. That is, in addition to CO, CO2, H2CO3, carbonate, other carbon containing compounds are organic compounds. But note that not all organic compounds are covalent compounds, such as "two ferrocene" and so on.
The exhaust gas generated by the project mainly includes the sodium acetate boiler soot and smoke stove. The fuel of the boiler by using firewood, flue gas scrubber, comply with the "emission standard of air pollutants" (GB13271-2014) in coal-fired boiler standard, through the 25 meter high chimney emissions. The fuel stove firewood, flue gas by using water bath dust collector, comply with the "emission standard of air pollutants" (GB13271-2014) in coal-fired boiler standard, through the 20 meter high chimney emissions. Enterprises should strengthen management and adopt advanced production technology and equipment with good sealing performance, and adopt effective measures to strengthen the control of the emission of unorganized waste gases.
Jiangsu LTAOP adopts AOP technology to treat sodium acetate acidic waste gas. After the reaction of sterilization, disinfection, deodorization and organic reaction, hydroxyl radical is produced with CO2, H2O and harmless carboxylic acid. Oxidation catalyst for the precious metal oxides, oxidation agent in the presence of catalyst to produce hydroxyl radical with strong oxidation (OH), these free radicals can decompose almost all organic compounds, which contained hydrogen (H) and carbon (C) oxidation of water and carbon dioxide. In addition to power consumption and water consumption, no other raw materials are consumed, no two pollution is produced, and no two treatment is needed.
The main waste gas of this project is acetic acid water vapor, which contains acetic acid water vapor, which is discharged after condensation and purification (99% efficiency). Acetic acid belongs to non-toxic substance, and it has little influence on environment after taking measures.
The Dragon Tai environmental protection by LTAOP process in line with national and local industrial policy, cleaner production, circular economy, various environmental protection facilities with reasonable, reliable and effective, the overall evaluation of the regional environmental impact. This report argues that, in the full implementation of environmental pollution prevention measures in the EIA and related requirements under the premise, from the environmental point of view, the construction of the project is feasible.
