| Abstract: | The chlorohydrination process for production of 40 000 t/a propylene oxide （PO） at Befar Group Co. , Ltd. is introduced. Improvements are carried out to solve the problems of high alkalinity of PO after using calcium carbide sludge as saponifying agents. The alkalinity of PO is not higher than 5× 10^-6 K when the gas phase pressure at light component tower overhead stabilizes at about 175 kPa and thus meets user requirements. |
