Asphaltene deposition is a challenging problem in the oil industry in many regions around the world. Due to the tendency of this petroleum fraction it precipitates and deposits in the wellbore, near wellbore region, and surface facilities, as a result of changes in pressure, temperature, and composition. Prediction of asphaltene phase behavior is important in order to avoid possible problems that can occur with their deposition. The aim of this thesis is to compare predictions of asphaltene phase behavior of two thermodynamic models, PC-SAFT and CPA. For such purpose commercial software HydraFLASH and Multiflash were used. The differences between models’ prediction of asphaltene phase behavior was investigated for both lower and upper asphaltene phase boundary.
