| titleOfInvention | Method and equipment for recovering and purifying waste solvent ethanol-cyclohexane-piperazine |
| abstract | The invention discloses a method and equipment for recovering and purifying waste solvent ethanol-cyclohexane-piperazine, which has the beneficial effects that components in the waste solvent ethanol-cyclohexane-piperazine are separated by a method of rectification separation, extraction separation, distillation separation and coupled membrane dehydration separation, water and various impurities are removed, the waste solvent ethanol with the purity of 50-60 percent (wt), cyclohexane with the purity of 30-45 percent (wt) and piperazine with the purity of 3-8 percent (wt) is purified to industrial absolute ethanol with the purity of more than or equal to 99.9 percent (wt), industrial cyclohexane with the purity of more than or equal to 99.5 percent (wt) and anhydrous piperazine with the purity of more than or equal to 99.5 percent (wt) through a series of processes with low energy consumption, so that the waste solvent ethanol-cyclohexane-piperazine can be recycled, the pollution degree of the waste solvent to the environment is reduced, and the purified solvent can be recycled, the production cost is saved. The purification method provided by the invention also has the advantages of high yield, low energy consumption, capability of recycling, simple and convenient production process, stable operation, suitability for industrial production and the like. |
