Propuesta de negocio para la implementación de ciclo rankine orgánico (ORC) en la recuperación de calor residual de hornos de coque para la empresa Trancora S.A.S

Abstract

In the coke manufacturing process there is a thermal waste at the smoke outlet of the ovens, the aforementioned waste is not usually used for other processes, except for preheating the coal before entering the cooking stage, on the other hand, there is a technology that has been gaining preference in recent years and whose function is to transform thermal energy into electrical energy, similar to the well-known conventional rankine cycle, called the organic rankine cycle (ORC). The ORC is a compact system that, by means of a heat transfer fluid, transforms thermal energy into electrical energy, with the characteristic of taking relatively low heat sources (from 70 °C it is already most useful). Specifically in Colombia, 2 ORC projects were successfully installed to recover heat from oil processes in the year 2020. Trancora S.A.S is a coke producing factory, which, on the one hand, has high thermal waste and, on the other hand, pays electric bills very high, this project aims to provide a business model, where the economic, technical and financial feasibility of implementing an ORC system in the coke manufacturer's main yard-workshop is studied and supports the solution of the problem.
