Features of Inner Finned Tube Heat Exchanger and Analysis of Its Application in Cyclohexanone Plant

It is a major subject in the technological advance of heat exchanger design regarding how to raise the exchanger's heat transfer coefficient K and the coefficient of heat convection α for vapor liquid heat exchange with vapor in the tube pass. The structure of inner finned tube heat exchanger and the calculation method of the coefficient of heat convection for tube pass fluid is introduced .The example of the heat exchange flow in the cyclohexane column top condenser of the 60 kt/a cyclohexanone project is taken, and the calculation results are compared between the tube shell heat exchanger and the inner finned tube heat exchanger, and it is concluded that it is beneficial to select inner tube heat exchanger both in terms of technical parameters and economic considerations.
