El objetivo de esta investigación fue la construcción de un módulo experimental que utiliza un inyector Venturi y un lecho empacado para conseguir un grado de carbonatación adecuado que en la práctica industrial son cuatro volúmenes de dióxido de carbono por cada volumen de bebida carbonatada. Los resultados experimentales para un refresco con 10.5 º Brix, a una temperatura de 6 ºC +/- 1 ºC, una presión manométrica de 1.85 bar, y para un caudal de 7.2 L / min, fue posible incorporar cuatro volúmenes a la bebida de carbón. dióxido de carbono por cada volumen de refresco. Los resultados permiten utilizar el Venturi acoplado al lecho empacado como una adecuada configuración compacta que facilita una mayor absorción debido a la formación de microburbujas de dióxido de carbono ofreciendo una alta área de contacto entre las fases y homogeneización dentro del lecho empacado...

THE TEXTILE INDUSTRY IS KNOWN FOR ITS EXCESSIVE WATER CONSUMPTION AND ENVIRONMENTAL IMPACT. ONE OF THE MAJOR CHALLENGES IT FACES IS MANAGING POLLUTION GENERATED BY DYES, PARTICULARLY BIFUNCTIONAL DYES, SUCH AS SUMIREACT SUPRA YELLOW S-HBU, WITH A RED APPEARANCE AND SUMIFIX SUPRA LEMON-YELLOW E-XF, WITH A YELLOW APPEARANCE. THIS STUDY AIMED TO INVESTIGATE THE DECOLORIZATION KINETICS OF SYNTHETIC SOLUTIONS OF SAID BIFUNCTIONAL DYES, WHICH COMPRISE TRIAZINE AND VINYLSULFON. WE CONDUCTED VARIOUS TESTS, INCLUDING MODIFICATIONS OF PH, THE ADDITION OF TIO2 P-50 NANOPARTICLES, EXPOSURE TO SOLAR RADIATION, LIMITED CONTACT WITH OXYGEN, AND EOLIC AGITATION. THE INITIAL SOLUTIONS HAD A CONCENTRATION OF 1000 PPM OF TEXTILE DYE. THE STUDY SHOWED THAT THE REACTION ORDER FOR THE “RED” SOLUTIONS IN THE R6 AND R9 REACTORS AND ALL THE YELLOW SOLUTIONS WAS ½. THE CONCENTRATION OF NANOPARTICLES AND PH H...

The textile industry is known for its excessive water consumption and environmental impact. One of the major challenges it faces is managing pollution generated by dyes, particularly bifunctional dyes, such as sumireact supra yellow s-hbu, with a red appearance and sumifix supra lemon-yellow e-xf, with a yellow appearance. This study aimed to investigate the decolorization kinetics of synthetic solutions of said bifunctional dyes, which comprise triazine and vinylsulfon. We conducted various tests, including modifications of pH, the addition of TiO2 P-50 nanoparticles, exposure to solar radiation, limited contact with oxygen, and eolic agitation. The initial solutions had a concentration of 1000 ppm of textile dye. The study showed that the reaction order for the “red” solutions in the R6 and R9 reactors and all the yellow solutions was ½. The concentration of nanoparticles and pH h...
