Bonus Report: Heat Transfer Developments

Cost savings of 'zero-fouling' crude oil preheaters

Unique configurations of proven self-cleaning fluidized bed heat exchangers virtually eliminate fouling in this application

DeBoer, E. F., Klaren, D. G., KLAREN BV; Sullivan, D. W., Whitson Sullivan Co.

A new way to make crude oil preheattrains more efficient is by employing "zero-fouling" heat exchangers. If all crude oil preheat trains in the world were equipped with zero-fouling exchangers, an annual savings of approximately $9.5 billion could be realized, assuming a crude price of $30/barrel. Understanding fouling. Crude oil preheaters play an essential role in crude oil distillation. Fig. 1 shows the function and location of these crude oil preheaters in the distillation process. The cold crude is heated to the furnace inlet temperature by either:  Fig. 1
