- W2259516146 abstract "Demand for lactic acid is growing, especially, for its use in the production of biodegradable polymer (polylactate).The current production method of lactic acid is both expensive and unsustainable. Therefore, there is great scope for development of alternative technology that will offer efficiency, economic and environmental benefits. One of the promising technologies for recovery of lactic acid from fermentation broth is reactive liquid-liquid extraction. In this paper the extraction and recovery of lactic acid based on reactive processes is examined and the performance of a hydrophobic microporous hollow-fibre membrane module (HFMM) is evaluated. Firstly, equilibrium experiments were conducted using organic solutions consisting of Aliquat 336 and trioctylamine (as carriers) and tributyl phosphate and sunflower oil (as solvents) The values of the distribution co-efficient (defined as a ratio of the concentration of lactic acid extracted over that remaining in the aqueous solution) were obtained as a function of feed pH (range 4.0 - 6.5), composition of the organic phase (ratio of carrier to solvent) and temperature (range 8 - 40 C). The best extraction was obtained with the organic phase of 15wt% tri-octylamine (TOA), 15% Aliquat 336 dissolved in 35 wt% tri-butyl phosphate (TBP) and 35% sunflower oil. The percentage extraction from 0.1 M was approx. 70% after 4 hours at pH 5.0 and at 35 C at a recirculating flow rate of 15-20 L/h. Lactic acid was re-extracted from the organic phase by using 0.5 M sodium carbonate solution and approx. 90% recovery was obtained in 4 hours. These results suggest that not only the hollow-fibre membrane process is possible and economic, the in situ nature of this could maintain lactic acid concentration at low levels during the fermentation to suppress the product inhibition and thus improve the productivity." @default.
