Device and method for quickly taking away reaction heat in preparation of propylene oxide by HPPO method |
| abstract |
The invention provides a device and a method for quickly taking away reaction heat in preparation of propylene oxide by an HPPO method. The invention selects the high-temperature low-pressure refrigerant to match with the condensing device and the liquid separating device, can achieve more ideal heat taking effect with less or even without circulating water, and greatly reduces the operation and subsequent maintenance cost. |
