Simulação de trem de pre-aquecimento de petroleo visando estudo da incrustração

TL;DRAbstract

Peltrollerum u i t !m c u u , u d'em:ancts a large amonnt energy.it ís interesting to use the energy from distillation columns prodncts to which is accomplished heat-exchangers, grouped a set known as pre-heating battery.msnuamm process depends widely from a good the pr<o-h<õatiing battery.Deposits (fouling) on heat exchangers constitute a problem because they increase pressure drop and emission from the fumace caused by a larger fuel consrumption.This work simulated shell and tube heat-exchangers as present in rel:Jmõry pre-heating batteries to drops were calcul.ate:dBell's tubes, they were according to methods mentioned the literature.Ali processing data, physical properties and exchanger dimensions were obtained from design data at Paulínia Refinery (Replan) and literature.The simulator provided coherent results for the internai and externa!tube heat transfer coefficients, global heat transfer coefficients, pressure drops, heat transfer rates and other pararneter involved with the h
