In the production process of industrial benzoic acid, the environmental protection issues that need to be paid attention to mainly include the treatment of wastewater, waste gas and waste residue, as well as energy consumption, energy conservation and emission reduction.

Wastewater treatment: A certain amount of wastewater will be generated during the production of benzoic acid, which may contain organic pollutants such as benzene, toluene, and xylene. If this wastewater is discharged directly without treatment, it can have a serious impact on the environment. Therefore, it is necessary to adopt appropriate wastewater treatment methods, such as biochemical treatment, physicochemical treatment, etc., to ensure that the wastewater meets the discharge standard before discharge.
Waste gas treatment: Some waste gas will be generated in the production process of benzoic acid, mainly including incompletely burned organic matter, volatile raw materials and solvents in the reaction process. If these exhaust gases are directly emitted, they will cause pollution to the atmospheric environment. Therefore, it is necessary to take appropriate waste gas treatment measures, such as combustion, adsorption, absorption, etc., to reduce the impact of waste gas on the environment.
Waste residue treatment: Some waste residue will also be produced in the production process of benzoic acid, such as catalyst residues, reaction by-products, etc. These residues, if discarded or disposed of inappropriately, can contaminate soil and water bodies. Therefore, it is necessary to adopt reasonable waste residue treatment methods, such as solidification, incineration, landfill, etc., to ensure the safe disposal of waste residue.
Energy consumption and energy saving and emission reduction: The production process of benzoic acid requires a large amount of energy, such as electricity, steam, etc. In order to reduce energy consumption and reduce production costs, it is necessary to take energy-saving and emission reduction measures, such as optimizing the process, updating energy-saving equipment, and improving energy efficiency.
In short, in the production process of industrial benzoic acid, we must pay attention to environmental protection issues, and take effective measures and methods to ensure that the production process meets environmental protection requirements and achieves sustainable development.
