This paper outlines the design and analysis of a shell and tube heat exchanger in an ethanol production line using corrugated tubes to enhance performance. Fouling, corrosion, and degradation of materials are some of the challenges of ethanol production processes that may reduce the efficiency and lifetime of heat exchangers. To overcome these problems, a shell and tube exchanger was designed that had corrugated tubes to enhance the amount of heat transfer and minimize maintenance needs. Computational tools were used to develop and analyze the design. The simulation results were used to assess the thermal per-formance (temperature distribution) and structural integrity (stress, displace-ment) of the heat exchanger. The important design parameters, such as heat du-ty, overall heat transfer coefficient, heat transfer area, and pressure drops were determined to make sure that thermal and mechanical requirements are satisfied. The selected material, stainless steel 316 (SS316), offers better corrosion resistance and durability in an ethanol processing environment. Simulation analy-sis proves that the heat transfer between the ethanol vapor and the cooling water is efficient, and the corrugated tubes have high heat transfer rate, but the pres-sure losses are within the acceptable range. Structural analysis shows that the stresses are far below the yield of the material, which means a safe design. Relative to smooth tubes, the corrugated configuration showed a clear 13% increase in outlet temperature, supporting enhanced energy recovery in ethanol processing.
