| titleOfInvention | A kind of propylene oxide production device and dehydration process of cumene hydrogen peroxide and cumene in production process |
| abstract | The invention discloses a propylene oxide production device in the technical field of chemical dehydration and a dehydration process of cumene hydroperoxide and cumene in the production process, including a neutralization tank, a neutralization settler, a water circulation pump, a prefiltration water separator, dehydration tower primary preheater, dehydration tower secondary preheater, dehydration tower, dehydration tower reboiler, dehydration tower overhead condenser, dehydration tower reflux pump and water pump, this kind of propylene oxide production The dehydration process of cumene hydrogen peroxide and cumene in the device and its production process is designed. The process route of neutralization and dehydration of CHP/CUM and lye solution is designed. After the pH value of the system is adjusted by the lye solution, CHP can be completely removed. The water in /CUM, the CHP/CUM obtained after dehydration meets the reaction requirements of anhydrous and oxygen-free cyclization reaction, the water content is controlled to 0%-0.01%, no external heating source is required, and the efficient use of energy is realized. To achieve lower energy consumption, it has the advantages of high dehydration efficiency and high energy utilization rate. |
