Condiciones óptimas de operación en el pulpeo de bagazo con etanol para la fabricación de cartón ondulado.

In this paper are presented the results obtained in experiments where the traditional pulping method of bagasse is substituted to obtain semi-chemical pulps used as reactive caustic soda, destined to the production of cardboard, by organosolv pulping using bio-ethanol as deslignifying agent, as a way to minimize the pollution in the paper industry. In this study were evaluated 14 physical properties with the objective of analyzing in a wide spectrum the influence that this kind of pulping has above the board paper properties. The experiments were carried out at Pilot Plant level, and the independent variables chosen were: ethanol per cent, soda per cent, and degree of grinding. The results were analyzed by using Statgraphic software. The optimal operation conditions were obtained using LINGO software, through which it was applied the hierarchic optimization method.
