AB  - In this paper the multistage membrane pertraction (simultaneous extraction and reextraction) of phenol with linear monoalkyl cyclohexane (IMACH) as a carrier and sodium hydroxide solution as a strip, in laboratory scaled pertractors with polysulphone hollow-fiber membranes, was investigated. Two types of pertractors were used, one being "fiber-in-fiber" type, and the other "fiber-by-fiber" type, both with parallel countercurrent flow of three independent liquid streams (feed, extragent and strip). The best results were obtained with feed and strip flow rates low and equal, while the organic flow rate was four times higher. Efficiency is higher for lower phenol concentration in feed, and higher alkalinity of stripping solution. It was shown that the pertraction of phenol with IMACH as an organic carrier is an extraction step-limited process. For that reason the "fiber-by-fiber" type of pertractor offers better constructive possibilities, since it enables combining larger number of fibers for extraction step with a corresponding smaller number of fibers for the Stripping step, which is not possible in the case of the "fiber-in-fiber" type of pertractor.

AB  - Phenol extraction from aqueous solution and its simultaneous concentration into caustic stripping solution using a hollow fiber-in-fiber type membrane contactor was investigated. The phenol separation rate using sunflower oil in gasoline (1:1) as an organic liquid was studied for once-through mode operations. Individual film mass transfer coefficients on the shell side, the tube side and the annulus, as well as the membrane mass transfer coefficients were isolated using Wilson's plot technique. From application of the film theory, and the resistance-in-series approach, the contribution of the individual mass transfer resistances to the overall mass transfer resistance is considered.

AB  - A mathematical model of thermal desorption with internal electroresistive heating of the adsorbent is postulated for a single particle. Three parallel mechanisms are considered: surface diffusion, pore diffusion and thermal diffusion. The resulting system of partial differential equations is solved numerically using orthogonal collocation. Using the model, computer simulation is performed and the influence of different model parameters investigated. The advantage of desorption with internal sorbent heating (such as electrothermal desorption) is proved.
