Regarding the pipeline blockage issue in the chemical production section?
Thread Content
I would like to ask those who have experience working in the chemical production sector: among the numerous pipes in the chemical production area, which ones are more likely to get clogged? Thank you all! ! !
Areas with large temperature fluctuations, condensation stage
Ammonium sulfate crystallization tube, crude benzene washing tube, and condensate return tube (high in naphthalene)
Areas that are prone to blockage include the condensate pipes for discharging cold liquid (including the liquid discharge pipes and the spraying pipes), the mother liquor pipes containing ammonium sulfide crystals, and the oil-washing pipes for crude benzene (especially the oil-rich pipes). The reason for blockage is essentially low temperatures, which cause naphthalene or ammonium sulfide crystals to precipitate. The solutions mainly involve insulation, heat tracing, or raising the temperature of the liquid inside the pipeline.
