performed, the heat exchanger still achieves the required heat duty. Sometimes determining sufficient excess heat transfer area or additional heat exchangers to take into account the effects of rapid fouling processes can make up a significant part of the whole heat exchanger design problem. The optimum thermal design of a shell and tube heat exchanger involves the consideration of many interacting design U the overall heat transfer coefficient (kJ/h-m2 oC, Btu/h-ft2-ºF) The correction factor F t for a heat exchanger which has 1 shell pass and 2 or more even number of tube.

LMTD Correction Factor a heat transfer surface area equal to or larger than As. 16‐04‐ 7 • Assumptions made in the derivation of the temperature correction factor Ft, in addition to those made for LMTD: • 1. Equal heat transfer areas in each pass. The optimum thermal design of a shell and tube heat exchanger involves the consideration of many interacting design U the overall heat transfer coefficient (kJ/h-m2 oC, Btu/h-ft2-ºF) The correction factor F t for a heat exchanger which has 1 shell pass and 2 or more even number of tube. Apr 18, · Hysys: Heat Exchanger Shows "ft Correction Factor Is Low" - posted in Chemical Process Simulation: Hello All, I operate heat exchanger in Hysys and it shows "ft correction factor is low". What does this mean? How can I solve this problem? Thank you in advance Cherlean. Heat exchangers are used to transfer heat between two sources. The exchange can The correction factor is used in conjunction with the LMTD to account for the deviation from the ideal counter-current flow pattern. For example, shell and tube (16 ft) long. SIZE 17– TYPE CEN. Here, the LMTD formula assumes pure countercurrent flow. Ft is correction factor, on LMTD for co-current and cross-flow heat exchangers. Ft is one for pure countercurrent flow. Minimum value of Ft should be between and Ft is a measure of heat transfer efficiency and temperature cross. A low value of Ft indicates reverse heat flow in some part. In HYSYS, you can choose the Heat Exchanger Model for your analysis. Your choices include an End Point analysis design model, an ideal (Ft=1) counter-current Weighted design model, a steady state rating method, and a dynamic rating method for F‹ = LMTD correction factor The heat transfer coefficient and the surface area are often. performed, the heat exchanger still achieves the required heat duty.
