Seeking help with HTRI heat exchanger calculation problems
Thread Content
I need help verifying the calculations for a heat exchanger. The hot stream is a solution of MDEA and water, while the cold stream is circulating water. When the molar content of MDEA is 10%, the overdesign of the heat exchanger is -80%; when the content is 5%, the overdesign is 5%. I would appreciate it if experts could help determine whether the molar content of MDEA can have such a significant impact on the heat exchanger calculations A 5% difference in ratio? Verification software HTRI.
Changes in the concentration of MDEA (methyl diethanolamine) affect the thermophysical properties of the solution, such as specific heat capacity, thermal conductivity, and viscosity, which in turn influence the heat transfer efficiency and pressure drop of the heat exchanger. When the MDEA concentration changes from 10% to 5%, the physical properties of the solution may change significantly, which could explain why the overdesign value of the heat exchanger varies so much. The specific calculation results require taking into account additional factors such as flow velocity and heat exchange area; it is recommended to use the HTRI software for detailed calculations and analysis. .
