👉 Exchange engineering, also known as process exchange or heat integration, is a technique used in chemical and process engineering to improve energy efficiency by transferring heat between different streams within a process. The goal is to minimize the energy consumption required for heating and cooling by utilizing waste heat from one part of a process to preheat another part. This is typically achieved through the use of heat exchangers, which are devices designed to facilitate thermal energy transfer without mixing the streams. By optimizing these exchanges, engineers can reduce operational costs, lower greenhouse gas emissions, and enhance the overall sustainability of industrial processes.
