What are the blockages in the gas pipes in the coke oven basement?
Thread Content
As the title suggests, black paste-like substances and white hard lumps are often found in the gas distribution pipes in the coke oven basement. What are their components, and what causes them? I earnestly request the guidance of my seniors.
Light it with fire and see if it burns
It happened at a coking plant before. Coking: There’s another problem with your chemical products – why is there so much ammonium salt again? Chemical products: That’s not an ammonium salt. Do you think ammonium salts dissolve in water? It was taken to the laboratory; after testing, it was also confirmed to be an ammonium salt
The gas purification effect is not very good; increase the temperature of the gas preheater so that these substances burn in the combustion chamber, rather than accumulating in places such as the horizontal tubes.
Combustion increases the concentration of pollutant emissions
The condensation of Northern Gas during transportation needs to be properly controlled
It should be tar and naphthalene; the cause is mostly incomplete purification of gas. If the temperature is too high after gas purification (a phenomenon that can be observed in coking workshops), or due to issues with the recovery equipment, the solution is to coordinate with the recovery workshop; before normal operations are resumed, the temperature of the preheater can be increased slightly to prevent substances from condensing. In winter, it is necessary to ensure proper insulation of the basements.
Naphthalene, sulfur, etc., pipeline corrosion residues, etc
