Metodología de protección de equipos para la Refinería Esmeraldas mediante la instalación de un aislante térmico con Perlita Expandida

Abstract

This project was carried out with the purpose of developing a methodology of thermal insulation in tanks and pipes, which is distributed in the different petroleum derivatives in the Esmeraldas Refinery. Knowing the different types of thermal insulation used in the refinery that emphasize the use of expanded perlite for this purpose. From the specification UOP 9-11-1 a change in the thermal insulation material of calcium silicate by expanded perlite is proposed. This technique includes step by step the following procedures: surface cleaning, inspection and installation of the new thermal insulation system. An analysis of production costs of the installation of the materials was carried out, resulting in a lower price for the expanded perlite insulation system. Finally, the heat transfer speed of the insulation systems is compared, obtaining a zero difference, due to the similarity of the thermal conductivity of the materials.
