“…Various designs have the flexibility to adapt into many industrial processes based on thermodynamics properties, temperature, pressure, fluids, stream phase, density, chemical composition and viscosity [1]. As a preheat train in crude oil refining process, it is fed by heating fluid in the network coming from downstream products, which the recovered heat can be considered as energy saving [2]. However, fouling is the main problem in this specific application because details of physical and chemical mechanisms in fouling formation are not clear and depend on several conditions.…”

The phenomenological model of fouling formation is investigated in this research which, the parametrization method based on the species and energy equation is implemented. It is shown that the previous empirical sigmoid-typed correlation can also be generated from the species equation as a special solution. Meanwhile, the fouling heat resistance is obtained from the phenomenological energy equation. Correlating these two solutions, it is shown that the proposed model generates key parameters of fouling formation characteristics of crude preheat train within all operational conditions. Thus, it generalizes the previous models as it covers wider operational range.

“…The heat exchangers of the BPA reuse the heat from the distilled fractions of the atmospheric and vacuum tower petroleum output to heat the incoming crude oil and maintain the thermal efficiency of the processes. According to [1], in only the petroleum preheating battery, the amount of energy consumed can reach 35-45% of the total energy consumption of a refinery. Thus, this reuse can lead to considerable savings.…”

The article delves into the intricate phenomenon of deposition in heat exchangers and how a piece of equipment known as the benchtop heat exchanger test instrument (BHETI) has been developed to expedite the examination of this phenomenon. The BHETI subjects samples to substantial stress, facilitating the assessment of an oil’s tendency to generate deposits. Tests were conducted on two crude oil blends referred to as blend A and blend B using a BHETI unit. This equipment permits testing under various controlled conditions, including temperature, pressure, and volumetric flow rate. The results indicated that blend A exhibited a higher susceptibility to deposition compared to blend B due to its elevated concentration of light hydrocarbons. The wall temperature exerted a significant influence on the deposition rate, with higher temperatures leading to elevated deposition rates. Conversely, lower oil flow rates resulted in increased deposition rates. Furthermore, extended-term tests unveiled fluctuations in deposition rates over time when blending the two oil samples, suggesting intermittent fouling processes, possibly attributable to thermodynamic imbalances induced by mixing, rendering the oil’s asphaltenes less stable. The outcomes were subjected to analysis employing the Colloidal Instability Index (CII), which indicated that the majority of samples exhibited values exceeding 0.9, signifying asphaltene instability. Additionally, the examination of saturated, aromatic, and NSO (nitrogen, sulfur, oxygen) fractions revealed decreased saturation and increased aromatics after the deposition tests.
