  • Patent number: 4992143
    Abstract: A continuous multistage process for separating a partially water soluble organic component from a slurry containing an insoluble solid, a partially water soluble organic component and optionally water. In this process, the slurry is continuously fed to a tower or column equipped with a suitable vapor/liquid contact device. Energy is applied at a point below the vapor/liquid contact device. Vapors containing the partially soluble organic component exit the tower or column overhead and the inorganic solid is recovered at the bottom of the tower or column. This application of distillation technology to slurries is particularly advantageous in that a more efficient separation of that solid material from the partially soluble organic component is obtained. The improved separation efficiency can be utilized to either lower separation cost and/or to affect a more complete separation in order to obtain a solid material with a lower residual amount of the organic component.
