dc.description | It was designed and built an electrodialysis unit to study the recovery like acetic acid of the acetate taken place during the anaerobic digestion of organic waste experimentally, using watery solutions of acetate of sodium to different concentrations (5 g/l, 15 g/l and 30 g/l) to simulate the liquor of anaerobic fermentation. The electrodialysis was carried out applying 8 different voltages periodically to the unit and monitoring the behavior of the main variables of the process. The maximum rate of achieved production of acetic acid was of 1674 mg/l and it was found that this went proportional to the applied voltage, flow of liquor of fermentation fed to the unit and the density of used current. The acetic acid was recovered in distilled water and additionally in a watery solution of Ethanol and it was rehearsed with success the estherification of this last mixture, being able to produce ethyl Acetate. The electrodialysis turned out to be a technically competitive alternative in principle, for the production of volatile fatty acids; because the obtained results demonstrate that it is possible to make it with relative easiness. | en-US |
dc.description | Se diseñó, construyó y operó una unidad de electrodiálisis para estudiar experimentalmente la recuperación como ácido acético del acetato producido durante la digestión anaerobia de desechos orgánicos, usando soluciones acuosas de acetato de sodio a diferentes concentraciones (5 g/l, 15 g/l y 30 g/l) para simular el licor de fermentación anaerobia. La electrodiálisis se llevó a cabo aplicando 8 diferentes voltajes a la unidad y monitoreando periódicamente el comportamiento de las variables principales del proceso. La tasa máxima de producción de ácido acético lograda fue de 1674 mg/l y se encontró que esta fue proporcional al voltaje aplicado, caudal de licor de fermentación alimentado a la unidad y a la densidad de corriente utilizada. El ácido acético se recuperó en agua destilada y adicionalmente en una solución acuosa de etanol. La electrodiálisis resultó ser una alternativa técnicamente viable en principio, para la producción de ácidos grasos volátiles, pues los resultados obtenidos demuestran que es posible hacerlo con relativa facilidad. | es-ES |
