Optimización del proceso de elaboración de papel tissue en la fábrica de papel higiénico del valle Favalle Cía. Ltda.

Abstract

The aim of this degree work was to optimize the tissue paper production process at the Valley FAVALLE Hygienic Paper Factory, looking an improvement in its efficiency. It started by collecting information on the parameters with which to work in each of the unit operations of the process, then a baseline diagnosis was made and samples of paste were taken at each point of interest to verify the conditions with which he worked; it was evidenced that the established parameters regarding the pasta consistency were not met. Therefore, it was decided the implementation of a work regime based on the manual control of paste consistency, through an inspection of the amount of raw material and water fed to the grinding device, the grinding time and discharge of the Pulper; a mass balance analysis was performed for the entire process quantifying the input and output flows of pulp, as well as the rejections of each equipment. Under these conditions, a production of 21.42 TPD of paper was obtained which gives an equivalent of 80% of efficiency for the process, unlike a 72% that had before the optimization in economic values this represents $ 2807, 64 daily that the company earns. It was determined that by operating the equipment with adequate consistency in the pulp an increase in its efficiency of 8% is achieved. It is recommended that the company install the appropriate instrumentation: consistency meters in the Pulper and level 1 box, pressure gauges and flowmeters in the pipes of the productive line.
