Evaluación Energética del Sistema de Calentamiento en una Refinería de Aceites Usados de Motor

Abstract

This paper describes the study of the energy analysis of the system thermal oil for a used motor oil re-refining plant, using PRO/II® software. This tool takes data from a real process and units modeling the equipment to simulating the operation of the equipment that makes up the process, it is capable of providing information on energy and mass data that will help to verify at which points in the process it is important to take advantage of energy and evaluate through an energy balance the energy potential of the evaluated thermal system. The study carried out in a refinery in operation, with a processing capacity of 1088.64 L/h of used motor oil, indicates that, in the boiler for heating thermal oil, it has an efficiency of 63.2 %, concerning to the total energy generated by the effects of a total and complete combustion of diesel. Likewise, an energy loss to the environment in the boiler of 8.33 % was determined, and there is an availability of energy recovery, from hot gases of 28.47 %.
