Diseño de un Sistema de destilación para la recuperación de Percloroetileno en el lavado de Poliuretano de la empresa la Fortaleza Ltda.

Abstract

A distillation system was designed for percholoethylene solvent recovery, used in the polyurethane soles manufactured by the company La Fortaleza Ltda., to reduce and optimize the volume consumption of solvent used. For the design the experimental determination was made in the init ial parameters lab and the behavior of the percholoethylene – silicone mixture to be distilled; through a simple distillation process establishing the required variables such as temperature, volume, performance and time. The optimal temperature to reach in the evaporated is 108 C, which occurs gradually and keep it constant. The system consists of three parts: a boiling tank 50 L power capacity (input), heated by a heating jacket wich houses diathermic oil and a pair of resistors, then the evaporated product is directed to a condenser where it is cooled and stored in a recovered product receiving tank. All made of stainless steel of ensure durability. Once the calculations and the necessary investigations were developed applying the lab standards to corrobora te with the desired product, a distillation system with 100% effectiveness which allowed to recover the solvent in a 90% from the initial charge. The application of distillation systems in the shoe industry allows saving to the company; keep a clean industry and the ecological balance in a healthy enviroment, so it is recommended to La Fortaleza Ltda. Company and related specific industries to apply the system and use this solvent.
