| titleOfInvention | Separation method for recovering olefin polymerization catalyst mother liquid |
| abstract | The invention discloses a separation method for recovering olefin polymerization catalyst mother liquid, and the separation method comprises the following working procedures of: (1), sending the catalyst mother liquid into a first fractionating tower C1; (2), returning a titanium tetrachloride gas phase evaporated by a scraped film evaporator to the tower kettle of the first fractionating tower from the top, extracting a high-boiling substance containing titanium tetrachloride at a tower bottom, and discharging the material from the bottom of the scraped film evaporator; and (3), sending the mixture of a hydrocarbon solvent and titanium tetrachloride into a second fractionating tower C2. The method has the following advantages: firstly, process flow is short, the quantity of equipment is reduced and investment in devices ia lowered, and furthermore the problem that the high-boiling substance blocks the towers is solved; secondly, the recovery rate of the titanium tetrachloride is improved, and the emission of wastewater and waste slag is reduced; and thirdly, the repeated condensation and evaporation of titanium tetrachloride are avoided, and the energy consumption of the devices is decreased. |
