Design and simulation of two phase hollow fiber contactors for simultaneous membrane based solvent extraction and stripping of organic acids and bases

For following process parameters: volumetric flow rate 1 m3 h−1, feed concentration 350 mol m−3, yield of BA in MBSE 85%, Reshell = 0.9, approach to equilibrium at the raffinate end of the HF contactor 0.40, and concentration factor of 10, the number of contactors of Liqui-Cel type 10 in. × 28 in. (Celgard) in series, without parallel lines of contactors, is five in MBSE and eight in stripping. In case when two parallel lines of contactors are used the number of contactors in series is two in extraction and four in stripping.
