Liquid-Liquid Extraction The actual configuration of mixers in multistage mixer-settlers and/or multistage columns is summarized in Section 15. A general handbook on this subject is Handbook of Solvent Extraction by Lowe, Beard, and Hanson. This handbook gives a comprehensive review of this entire operation as well. [Pg.1640]

In this process developed by Lurgi [17], the phenolic effluent is contacted with the solvent in a multistage mixer-settler countercurrent extractor (Fig. 10.8). The extract, containing phenol, is separated into phenol and solvent by distillation and solvent is recycled to the extractor. The aqueous raffinate phase is stripped from solvent with gas, and the solvent is recovered from the stripping gas by washing with crude phenol and passed to the extract distillation column. [Pg.437]

The first attempt in sizing of continuous multistage mixer-settler systems for hquid membrane processes was made by Cahn and Li [3]. Their membrane film model when extended to multistage systems with each stage being ot equal volume, the approximate volume per mixer is... [Pg.160]

Wardius [51] extended the advancing front model to be employed to multistage mixer-settler systems for liquid membrane operations. They presented a zero order solution to the perturbation equations based on the model developed by Ho et al. [29]. The emulsion globule residence time distribution in each mixer was assumed to be exponential and the fractional utilization of internal reagent was given by... [Pg.161]

As a standard appliance in the extraction of uranium, a multistage mixer-settler arranganent with concurrent flow of two phases, water and organic, is used. It can be replaced by novel design with membrane contactors that avoid the constraints of conventional systems. Manbrane extraction used for uranium recovery has many advantages over conventional methods, like no fluid-fluid dispersion, no emulsion... [Pg.692]
