The waste gas from the coking industry contains macromolecular and refractory oxidizable substances (such as methylnaphthalene, acenaphthene, biphenyl, anthracene, phenanthrene, pyrene, benzopyrene, etc.)
The waste gas from the coking industry contains macromolecular and refractory oxidizable substances (such as methylnaphthalene, acenaphthene, biphenyl, anthracene, phenanthrene, pyrene, benzopyrene, etc.). Most of these substances are irritating and corrosive due to containing different impurities; some even contain a large number of harmful components that are carcinogenic, teratogenic, and mutagenic; and some also contain malodorous substances. Its composition is complex, which can cause relatively serious pollution to the atmospheric environment, accelerate the corrosion of equipment, and improper disposal of some components may easily lead to safety accidents such as combustion and explosion.
Causes of Organic Waste Gas Generation in Coking Plants:
During the production process, when chemical products are transferred between tanks, gas is discharged through the vent pipe during feeding, or gas is volatilized due to temperature rise;
Waste gas generated from cleaning pipelines and equipment during the production process;
Short-term venting under abnormal equipment conditions and other abnormal production situations;
Waste gas generated from equipment leakage;
Waste gas generated from the overflow of chemical product tanks;
Some gases generated during production processes such as chemical reactions.
Brief Description of Treatment Processes
Generally, processes such as Regenerative Thermal Oxidation (RTO incinerator) and rotor concentration + RTO/RCO/activated carbon adsorption can be considered to prevent the emission of polluting gases. These processes are characterized by the ability to treat waste gas with very low pollutant concentrations, high purification efficiency, and the capability to eliminate smoke and deodorize. The processes are simple and easy to operate.
Recommended adoption: Regenerative oxidation/catalytic oxidation + waste heat reuse treatment technology. For waste gas with low concentration and large air volume, the rotor concentration + RTO/RCO/TO (Thermal Oxidizer) process can be used for treatment.
