Diseño y simulación de una torre de fraccionamiento del producto líquido de pirólisis de polipropileno, para la identificación de precursores químicos.

Abstract

The main objective of the project was to design and simulate a fractionating tower for the liquid product of polypropylene pyrolysis, for the identification of chemical precursors, since polypropylene in Ecuador, in addition to being a polluting material for the environment, requires a complex management for its elimination. When processing chemical precursors by means of a fractionating tower; it would contribute to the reuse of plastic waste. In this sense, for the design, in the first instance, it was analyzed whether the equilibrium constants depended on the boiling temperatures of the compounds found from the chromatography of the liquid phase of the pyrolysis of polypropylene, then 1 atmosphere pressure was established to iterate the equilibrium graphics in relation to boiling pressures and temperatures. All this as part of the manual calculation where the input variables required by the DWSIM program were determined and optimized to function as: number of plates, feeding plate and reflux ratio. In this sense and once the values of mentioned conditions of the 6 priority compounds have been stabilized; 87.16% of the light key component was reached, as well as 99.93% of the heavy key component in the bottom; own percentages of an optimized and successful simulation. It was recommended to compare the results of this research with other simulators, as well as the careful selection of the thermodynamic package based on the chosen compounds.
