| titleOfInvention | Device and method for continuous stripping and dealcoholization of trioctyl trimellitate |
| abstract | The invention discloses a continuous stripping and de-alcoholization device and method for trioctyl trimellitate in the field of chemical production. The stripping feed heater is connected to the stripping and de-alcoholization tower; the tower body of the stripping and de-alcoholization tower is provided with an upper packing layer, a middle packing layer and a lower packing layer; the top of the tower body is provided with a gas outlet; A superheated steam distributor and an upper heat-conducting oil heat exchange coil are arranged between the lower packing layers; a lower heat-conducting oil heat exchange coil is arranged in the tower body under the lower packing layer; the discharge port at the bottom of the tower body is connected to a sealed buffer tank. During operation, water and octanol are evaporated in the tower body; the descending trioctyl trimellitate is fully contacted with superheated steam in the middle packing layer, which promotes the further evaporation of octanol dissolved in trioctyl trimellitate; The trioctyl trimellitate that continues to descend is subjected to two heat exchange distillations to remove residual water and octanol. Its product quality is good, and its dealcoholization is safe and efficient. |
