At the same time, there is a growing concern with the search for renewable sources, aiming to reduce greenhouse gas emissions. In this context, one alternative that has gained prominence is energy recovery in thermal processes. It is known that a significant amount of thermal energy is wasted annually worldwide, especially in industries where saturated steam, resulting from heating processes, is released into the environment without being utilized. The recovery of this steam and its reintegration into the production cycle can reduce the total energy consumption of a process and contribute to lowering carbon emissions in industries that rely on fossil fuels for thermal energy generation. A widely used technique to recover this energy is mechanical vapor recompression, which consists of compressing the wasted steam until it becomes superheated and reusing it in the production cycle.
