Crude Preheat Train - New Design Concept
Crude-Preheat Train is a most important feature of the any atmospheric crude distillation unit (CDU) in the refinery. Virtually, refinery overall economy revolves around the performance of crude preheat train. Crude preheat train utilises CDU bottom product and pump around streams waste heat for preheating the crude oil fed to the column. For every degree of incremental gain in crude preheat temperature, append significant reward on refinery overall economy (OPEX) and vice versa.
This abstract underlines the conventionally designed crude preheat train underperformance rationales, and proposes a new design concept to address these ever since persisting problems.
