Diseño de un sistema para la recuperación de Percloretileno mediante el Método de destilación en INDUCALSA

Abstract

The distillatio n with rectification Tower desi g n was carried out in order to recover the PERC in inducalsa, by washing of soles in shoes manufacturing, to reduce the amount of waste and cos ts by reusing the solvent. Inducalsa generates every t w o months an aver age of 450 Kg of residual perchloroethylene - silicone, by producing an average of 30000 pairs of soles monthly in the area of PU, it should be paid by the fin al disposition 0,90 cents., for each kilogram of waste. We collect 20 samples for simple random in four weeks, to determine in the laboratory pH, density, viscosity, partial pressures, fractions of equilibrium curve and comparing the purity of recovered solvent with the material safety data sheet DIRSA using the spectrum go with which the distillate has the same characteristics of the pure PERC, then certain parameters were temperature, time and flows with their corresponding ranges for optimum performance, the designed equipment has a tank of boiling with four resistors, steam is fed to the column, at t he bottom of the column there is a feed tank where is pumped into the tank of boiling, a condenser coil; a distributor of power for reflux, as well as a container to store the solvent; the team processed 45,73 Kg/h. As a result, it was obtained a distillat ion tower with a yield of 48%, acceptable by the economic value of the solvent on the market and an efficiency of 75%, are positive results which indicate process residue solvent for 100% purity, equipment is very useful to reduce pollution, it allows savi ngs to pay the final disposal of the residue of Fund gain by purchasing less amount of solvent in the market, t hus contributing in the change of the productive matrix.
