Chemical Processing - June 2008 - (Page 43) flooded D1 Distillate product PLANT INSITES P1 Air-fin stratification Stratified liquid lem may occur if the air-fin has multiple tube passes. Phase separation in the header boxes may allow for some f looded tubes and some unf looded tubes in the exchanger. The air-fin situation requires an unusual combination of exchanger design, tube velocity and condensation curve characteristics. However, it can happen. A more common problem of the stratified air-fin is that once the heavier part of the liquid leaves the vapor, the remaining vapor may no longer be condensable. Many condensers of all types have failed to work due to this variant of vapor blanketing the exchanger surface. Again, never count on making one of the flawed subcooling approaches work — but at least understand why they may. ANDREW SLOLEY, Contributing Editor ASloley@putman.net Figure 3. Liquid that has separated from the vapor is susceptible to subcooling by external air. Were You Featured In This Magazine?
