| titleOfInvention | Propylene oxide concentration method and concentration apparatus |
| abstract | A method and apparatus for providing a concentrated aqueous solution that does not require much energy and contains at least 95% by weight or more of propylene oxide. In concentrating propylene oxide in an impure propylene oxide solution, the solution and water vapor are introduced into a distillation column, a gas stream containing propylene oxide is recovered, and then this gas stream (water vapor treated) is recovered. Solution) in at least two heat exchangers arranged in series, at an absolute pressure in the distillation column of 1.5-6 bar and in the heat exchanger, 5 ° C., under the pressure used A process for concentrating propylene oxide, characterized in that it is condensed continuously under the temperature of the cooling liquid in the last heat exchanger between 5 ° C. and below the condensation temperature of propylene oxide.
