Analogy Between Heat Exchanger and Packed Column Calculations




The analogy among momentum, heat and mass transport phenomena is an important concept in chemical engineering education. This paper presents the analogy between heat exchanger and packed column calculations. The effectiveness-NTU method used to calculate outlet temperatures of hot and cold streams in an exchanger is introduced in a packed column where outlet compositions of gas and liquid streams are to be determined. Examples are used to demonstrate the usefulness of the developed analogy.
