Redesign crude preheater train for efficiency

Over design of heat exchangers sourced to fouling problems

Singh, D., Van Wagensveld, S., Shedded Uhde Pty Ltd.

Excessive heat-exchanger fouling contributes to low heat recovery in many refinery crude preheat trains. Low heat recovery can result in operation problems such as product losses, reduced throughput, excessive loading of the crude distillation column, feed heater and more. A new design concept can minimize fouling in the crude preheat train. This approach can provide more operating flexibility while improving reliability of the crude distillation unit. Background. Many refineries struggle with low heat recovery in the crude preheat trains due to excessive heat-exchanger fouling. Reduced heat recovery in the preheat trains results in various operational problems. We will address the core is
