“…Because of excitation due to an alternating voltage, the crystal vibrates with a characteristic frequency. [39,40] The frequency variation is related to variation of the following factors: mass, viscosity density product of the media exposed to the crystal surface, and pressure. The mass variation per unit area at the QCN electrode (here metal) surface can be related to the observed variation in oscillation frequency of the crystal using Sauerbrey equation [41][42][43][44][45][46][47][48] :…”

Asphaltene deposition is a common problem in production operation; these problems cause obstruction through pore throats, production tubing, and also surface facilities. In this article, adsorption of asphaltene, obtained from a crude oil sample from Iranian southern oil fields, onto metal surfaces has been extensively investigated. The metal surfaces are aluminum, iron, and copper. The amount of adsorbed asphaltene was successfully measured with a novel method named as quartz crystal nanobalance. To model the prediction of asphaltene adsorption onto metal surfaces, a concentration dependent factor, X, was introduced. To account for the exact asphaltene concentration effect on both adsorption and desorption steps, the modified Langmuir isotherm was developed. Genetic algorithm was used to optimize the set of unknown parameters. The results indicated that good agreement was between model results for different metal surfaces and experimental data.
