Heat exchangers are vital components in chemical processing, playing a crucial role in transferring heat between two or more fluids at different temperatures. They are employed to conserve energy by recapturing heat from processes and repurposing it, which is essential in the stringent, regulation-bound, and energy-intensive chemical industry. Their design and operation vary depending on the specific needs of a process, whether it's heating, cooling, or maintaining a precise reaction temperature. By optimizing thermal management, these exchangers contribute significantly to the efficiency, safety, and cost-effectiveness of chemical manufacturing.
