A method for calculating asphaltene deposition in a pipeline based on Couette device experiments is developed. An internal cylinder of a Couette device is rotating while the deposit is formed on the immobile outer wall. The method is based on similarity of the boundary layer thicknesses and the velocity distributions across boundary layers in a Couette device and a pipeline if the shear stresses are equal to each other. The deposition rate in a Couette device Is characterized by an experimental parameter with velocity dimensionality. This parameter and the particle concentration at the wall determines the particle flux to the wall. This deposition rate parameter can be evaluated based on Couette Device experiments and then use for calculation of the deposition layer growth in a pipeline. This is an abstract of a paper presented at the 8th World Congress of Chemical Engineering (Montreal, Quebec, Canada 8/23-27/2009).
