Evaluation and comparison of different models for asphaltene particle deposition in flow streams

Study of asphaltene deposition in wellbores during turbulent flow

“…According to calculated average errors and to the study of the models' theory, Beal (1970) was selected to be used in the diffusion and diffusion-impaction regimes. That choice is in agreement with previous results presented by Shirdel et al (2012), who elected the models of Beal (1970) and Escobedo and Mansoori (1995) the most suitable to predict deposition. The preference by the first model in the present paper is due to the lower average error it presented in the validation study performed, which considered a wider set of experimental data in relation to previous works (including Shirdel's et al 2012).…”

“…The results obtained agreed with the experimental measures, but some parameters in the re-entrainment correlation had to be adjusted for that. Shirdel et al (2012) studied the application of some particle deposition models (Friedlander and Johnstone 1957;Beal 1970;Cleaver and Yates 1975;Escobedo and Mansoori 1995) to predict published experimental data. In the first part of the paper, they used Friedlander and Johnstone's (1957) aerosol data set, which was exempt of particle re-entrainment.…”

“…The main objective of the present work was to investigate the contribution of diffusive and convective mechanisms to promote the radial transport of asphaltene particles, complementing the first part of Shirdel's et al (2012) study with a more detailed investigation of particle-fluid interaction and with more published models and experimental data sets. Exclusively smooth vertical tubings were considered, which nullified the influence of pipe roughness and gravitational forces on transport rates.…”

A novel approach to oil production optimization considering asphaltene precipitation: a case study on one of the Iranian south oil wells

“…The most important classic models are based on the concept of turbulent flow and eddy diffusion (Eskin et al 2011). In this paper, among different models presented for the deposition of solid particles, Shirdel's approach has been utilized to model asphaltene deposition (Shirdel et al 2012). This model is the most comprehensive one to simulate the process of solid deposition.…”

“…The developed model includes three parameters, which should be empirically determined using the Couette device. Shirdel et al (2012) modeled Friedlander and Johnston (1957), Beal (1970, Escobedo and Mansoori (1995a and b) and Cleaver and Yates (1975) models as an integrated form ignoring electrostatic forces and thermophoresis effects between the wall and particle. They compared the results of models with available experimental outcomes.…”
