| 摘要 |
A mixture of an oil slurry phase and an aqueous phase is continuously supplied into a tower constituting a separation chamber and is retained in it for a time to stratify into respective upper and lower layers, from which the slurry and aqueous phase, respectively, are continuously drawn off and a portion of the drawn-off slurry is tapped and continuously discharged as a slurry product, while the remainder is continuously recirculated to the upper-layer slurry in the chamber. The mixture supply, slurry product discharge, and aqueous phase drawoff are so controlled as to establish and maintain a flow-continuity equilibrium in the chamber whereby the retained quantities of the slurry and aqueous phase are maintained constant.
