AB  - Crude oil fouling in processing equipment have been a major unresolved problem in petroleum
industries. The underlying behavior of fouling precursors present in the crude oil have to be investigated to
mitigate the deposit formations. In the present research, an attempt has been made to predict the asphaltenes
deposition rate from crude oil in a heat exchanger tube through discrete phase CFD simulations. Various forces
such as stochastic collision, thermophoretic, Saffman lift, coalescence and drag are applied on the particles to
understand the transportation and adhesion mechanism of the asphaltenes particles. As asphaltenes have the
tendency to aggregate irreversibly with different particle sizes, the transportation of asphaltenes particles is
studied through varying the particles diameters. The propensity of asphaltenes particles in a Lagrangian frame
is studied through the available discrete phase models in the commercial CFD Software Ansys Fluent.
