Pinch Analysis Application for Fouled Crude Distillation and Condensate Fractionation Units of a Refinery

Preheat trains of each Crude Distillation Unit (CDU) and Condensate Fractionation Unit (CFU) of a refinery in Malaysia were experiencing severe fouling. This led to lower heat recoveries of the pump arounds and higher fuel gas consumptions in the furnace and the reboiler of the units. Consequently,...
