SEPARACIÓN CON MEMBRANAS COMO MÉTODO ALTERNATIVO EN LA REFINACIÓN DE FRUCTOSA

Abstract

The refinement of fructose in the UEB derivatives Florida, is to carry out the bleaching by activated carbon adsorption. The use of this adsorbent involves a number of difficulties in the process and its economic impact is important because the need to buy abroad. This paper presents an alternative membrane separation technique that belongs to a group of clean technologies and is interesting in that it excludes the use of adsorbents and filtering. To evaluate the effectiveness of the procedure was performed a study on a small scale, making four experimental runs with membranes of different porosity at two levels of pressure. In each trial was measured permeate volume over time and color to each sample, the latter through spectrophotometry. The color removal behaved in the range of 86 - 95 %. Considering the average values of color and the permeate flux was selected as suitable membrane of 150 000 Da at a pressure of 7 atm. To develop this alternative to industrial flows must purchase a module type SC37 CARBOSEP. The investment is feasible, as demonstrated by NPV and IRR indicators. The production cost is lower by $ 26.28 / T to the traditional procedure. It is shown from a technical standpoint, economic and environmental that this variant has a number of advantages.
