| titleOfInvention | A process for recovering butanone from waste solvent in adhesive industry |
| abstract | The invention belongs to the technical field of recovery and extraction of butanone, and discloses a process for recovering butanone from waste solvent in the adhesive industry, comprising the following steps: firstly introducing the waste solvent into a thin film evaporator, and heating the waste solvent , and then condense the formed gas phase to form a condensate; introduce the condensate into a dehydrating agent, use the dehydrating agent to remove the moisture in the condensate, and introduce the dehydrated condensate into a delighting tower, reheat, and derive the separated recombination The heavy components are introduced into the butanone tower, and then heated to form butanone light components and heavy components containing toluene, the light components are introduced into the condenser for condensation, and butanone is produced; the heavy components containing toluene are introduced into the toluene column , and then heated to form toluene light components and residues, the toluene light components are introduced into the condenser for condensation, and toluene is produced. The invention solves the problem of the existing butanone recovery process, in which the loss of butanone is large during the operation process, resulting in a low recovery rate of butanone. |
