Original Article:

The fouling phenomenon entails undesirable costs for the main industrial sectors. In the oil and gas industry oil preheat battery exchangers have serious problems with this. In the present work, predictive models based on the deposition threshold were evaluated. The methodology was based on the original proposals and on modifications using parameter estimation with the minimization of calculated and experimental data. The results point to the deficiency of the models in predicting the fouling behavior in exchangers, considering the deposition in the hull and in the tube, since they were validated with tube data and with fixed values of physical properties.
