Abstract

In industrial production processes, waste heat is an important consequence, especially in sectors that
rely significantly on composites and polymers. Frequently, this heat is released into the atmosphere
without being captured, which raises operating expenses in addition to wasting potential energy. In
these sectors, waste heat recovery, or WHR, has become a key tactic for raising sustainability and
energy efficiency. The WHR potential of multistage air compressors—essential parts of industrial
manufacturing setups—is examined in this study. Businesses can cut their energy use and carbon
footprint by recovering waste heat. The efficiency of two popular heat exchanger technologies—plate
heat exchangers and shell-and-tube heat exchangers—in recovering heat from multistage air
compressors is assessed in this paper. Important variables including temperature differentials, specific
heat capacities, and mass flow rates form the basis of the analysis. The total recoverable heat in the
system is determined by these variables, which are crucial. The multistage air compressor systems
exhibited an outstanding 4883.65 kJ/min of recoverable energy, indicating a large potential for heat
recovery, according to our findings. Comparing the two types of heat exchangers, it can be shown that
plate heat exchangers recover 4256.82 kJ/min at a substantially higher efficiency than shell-and-tube
heat exchangers, which recover 3156.67 kJ/min. These findings highlight how crucial it is to choose
the right WHR technology in order to optimize energy recovery. The study emphasizes how important
it is to use cutting-edge WHR technologies to improve industrial sustainability. Industries may
significantly cut energy consumption, greenhouse gas emissions, and operating expenses by recycling
waste heat in an efficient manner. This will help to create a more sustainable and energy-efficient
future.

Keywords: Waste heat recovery, multistage air compressors, polymer manufacturing, composite manufacturing, heat exchanger.
