Winterization in accordance with API 661 Annex C may need to be considered by designers when air cooled heat exchangers are operating in climatic extremes. In order to prevent operating problems in-situ, a temperature safety margin should be added to the critical process temperature to determine the specified minimum tubewall temperature....

Designing for applications using viscous oils is challenging. These fluids vary widely in viscosity, generally have a low Reynolds number, and can experience substantial flow maldistribution. To account for the resulting uncertainty, traditional thermal designs often include large fouling factors. This webinar identifies typical design issues and discusses the methods and...

Xist can predict unexpected performances of shellside viscous fluids in laminar regimes, where thermal maldistribution is present. The heat transfer of viscous flows across vertical baffles is analyzed by CFD to determine impact of such non-uniformity. Maldistribution can be monitored using a viscosity-independent Richardson number. The Richardson relates the impact of...
