The defects of the condensation method are as follows:
because the waste gas also contains certain polymer impurities, the deep cooling energy consumption is large, and simultaneously, the condensed substance impurities are more, so that the condensing pipe is easy to block and is not easy to clean. Meanwhile, the concentration of the waste gas discharged after the condensation method is still high, and the standard discharge requirement cannot be met.
The defects of the adsorption recovery method are as follows:
at present, two types of commonly used adsorbents are provided, one type is activated carbon particles, the other type is activated carbon fibers, and the toluene waste gas is required to reach the standard and have low emission concentration (10-30 mg/m)3) Therefore, the standard emission is difficult to achieve after the first-stage adsorption treatment. Meanwhile, the filling amount of the activated carbon particles is large, the single-tank solvent adsorption amount is up to 500kg, and the operation safety risk is high.
