Beyond the Basics: Multi-Objective Optimization for Design of Heat Exchangers
May 21, 2025
Commercial heat exchangers in the process industries are designed according to standards from entities such as TEMA or API. The designer’s goal is to maximize the heat transfer coefficient and minimize cost, area, and pressure drop. However, these objectives often conflict. For example, changing a geometric design parameter such as tube...

CG-13 Modeling Spray Condensers
December 20, 2023
This report reviews and evaluates literature methods for modeling spray condensers. It discusses droplet size, distribution, motion, and mass and heat transfer in a hot vapor stream. The methods in the literature are sufficient for modeling spray condensation of a single component without a noncondensable gas. Limited research on spray condensation of...

Is My Design OK? The Challenges of High Effectiveness Exchangers
June 14, 2018
Temperature effectiveness is the change in process fluid stream temperature divided by the difference between the hottest and coldest temperatures in the exchanger. If the required effectiveness is greater than 0.8, non-ideal fabrication or variable process conditions can significantly reduce performance of many exchanger types (shell-and-tube, plate-frame, plate-fin, etc.). Learn about...
