Liquid phase solvents absorption from exhaust gas (stripper or abatement)

Absorption in a liquid phase is a solvents recovery process suitable for AIR/GAS flows containing high concentrations of high-boiling solvents. It is also very suitable for the recovery of chlorinated solvents.

For this process, abatement strippers are used, the solvents recovery is divided into two phases:
• 1. Abatement/Absorption
  The air flow containing solvents is directed to stripping column by a fan; it enters in the lowest part of the stripping column from the bottom side and, passing through high efficiency and low pressure drop filling bed, meets the abatement liquid which is fed to the stripper from the column head. The gas leaving the column is released in the atmosphere, free from the solvent and then purified. The abatement liquid containing the recovered solvent will be sent to the second recovery phase, that is the distillation.
• 2. The distillation of the effluent liquid coming from the strippers, allows to recover and purify solvents to reuse them in the production process.
