Fouling of pre-heat train heat exchangers and process heaters used for the crude-distillation unit is a major unsolved problem which costs the industry in terms of energy inefficiency and productivity loss. The complexity of the fouling problem has prevented the industry from developing effective mitigation methods. Coking is a general term used for fouling at high temperatures, because the structure of the deposition resemblance to coke. Exxon Research and Engineering Co. conducted a joint research project with the US Department of Energy. One part of the research was to conduct coking experiments for crude oil subjected to heat fluxes greater than typical industrial conditions. In the present study, the coking data are re-analyzed and a simplified model is developed for predicting threshold fouling conditions. Recommendations are made for future experiments and analysis of the laboratory and field data.
