Why is Industrial Formaldehyde Production Less Polluting?

Hydrogen Peroxide Plant Supplier analyzes the environmental pollution of formaldehyde production from industrial formaldehyde production.

At present, the main sources of pollution in China's formaldehyde industry are waste gas, wastewater and noise.

For the treatment of exhaust gas: Most of the formaldehyde produced in China uses the silver process. In the production process, methanol and air, water vapor enter the reactor, and oxidize and dehydrogenate under the catalysis of the silver catalyst to form formaldehyde. The oxidation reaction of methanol starts at about 200 ° C. The heating process is heated by an electric heater, and no boiler heating is required, thereby reducing the pollution of the coal-fired boiler to the atmosphere. On the other hand, Formaldehyde Production Plant produces exhaust gas during the process of formaldehyde production. The process uses a tail gas processor to burn off the polluted gas in the exhaust gas, and converts the heat into steam through a heat exchanger, which can be connected to the steam pipe network.

For wastewater treatment: the waste water from the Formaldehyde Production Process, the intermediate control analysis residue can usually be sent to the absorption tower as an absorption liquid; the waste liquid that cannot be used as the absorption liquid will be sent to the sewage treatment station for treatment.

About noise reduction: The noise source in the Formaldehyde Production Process is mainly the Roots blower. The general manufacturer will place the blower separately in the soundproof room, and install a silencer on the inlet and outlet pipes of the blower to reduce noise pollution.
