“…While carbon steel is used as the tube material in the industrial heat exchangers, the fouling probes are made up of stainless steel due to difficulties in fabricating the probes in which the heater rods embedded with thermocouples are inserted. Normally, accelerated 17. Parity plot of the initial fouling rates predicted by the proposed model (special case) vs. the experimental data for crude oils A and B.…”

“…[13]. Laboratory units such as stirred batch cells [14] [15], and recycle flow loop with tubular [16] or annular cross-section [17] [18] are widely used for fouling studies. Theories describing asphlatenes adhesion inside the tubes of heat exchangers were proposed [19] and computational fluid dynamics based fouling prediction approaches were also used by a few researchers to predict precursor/asphaltenes deposition on heat transfer surfaces [20].…”

The continual decline in the quantity of legacy Pennsylvania grade crude oil coupled with recent volatile crude oil prices has prompted American Refining Group to start processing a wide variety of opportunity crudes to expand its crude oil feedstock slate to maintain profit margins. As opportunity crude usage increases, crude oil fouling and unexpected corrosion have become major issues in the refinery crude unit's hot heat exchanger train (HHET) and other process units. Crude oil fouling in the refinery has resulted in increased energy consumption, reduced throughput, and more frequent shutdowns. In this work, fouling at the refinery crude unit HHET resulting from the impact of Pennsylvania grade crude blended with opportunity crude oils was investigated. Thermal and hydraulic fouling models were studied to detect changes in the fouling behavior of the crude unit's hot heat exchanger train. Phase separation of crude oil to coke fouling mechanism was described in detail. Several crude oil fouling diagnostic tools were used to determine the root causes of fouling including foulant chemical characterization, crude oil compatibility, caustic injection evaluation, crude furnace operation, crude corrosion, and in-house developed fouling indices.

“…The simulation showed some interaction between fouling within and outside of the tubes and establishes impact of fouling on flow patterns, heat transfer coefficient and pressure drops. Ho (2016) examined the behaviours of five crude oil whose effluent temperatures decline because of foulant deposition on the wall, in the laboratory. The study developed a fouling model for the analysis of the behaviour of crude oil and interpretation of fouling data obtained with a widely used laboratory unit.…”

Heat exchangers as a heat transfer device has gained wide applications across different levels of domestic and industrial set-ups. Various studies have been carried out to study, analyse and predict its performance. However, one major phenomenon that limits heat exchanger performance is attributed to fouling. Based on this, various studies and approaches have focused on reduction, elimination and mitigation of fouling. This study therefore focused on this. It reviewed several attempts that have been carried out to understand and mitigate the incidents of fouling in heat exchangers. The study found that despite the existing models developed towards understanding fouling, there is no single model that has provided an accurate prediction of fouling in all the different types of heat exchangers. Also, majority of existing results have limited applications and some of the solutions are only peculiar to particular type of heat exchanger. Further to this, majority of the study results only pointed to small scale laboratory test schemes and there is absence of in-situ measurements that predicts actual (real life) service performance.
