Thermodynamics of wax precipitation in petroleum mixtures

Compositional Modeling of Wax Formation in Petroleum Mixtures

Heavy organics deposition is a common problem in oil industry, especially in oil production, transportation and processing. Wax or solid paraffin series are examples of heavy organics that deposit. Precipitation and crystallization of wax causes major difficulties in different processes. Based on multi-solid theory, a basic model is modified in this paper for wax precipitation in different oils...

Solid Phase Equation of State Application for Wax Formation Prediction in Petroleum Mixtures

Precipitation ofsolid paraffins is one ofthe most common problems in the oil industry, imposing high operating costs. There have been a great many efforts for the prediction <span style="font-size: 10p...

Penicillin in oil-wax mixtures.

One of the main disadvantages of penicillin as a chemotherapeutic agent is that the kidney is able to eliminate it from the blood in a relatively short time, making it necessary that injections be repeated fairly frequently in order to maintain a therapeutic blood level for a long period. This is, of course, most undesirable from the patient's point of view and many workers have attempted to fi...

Effect of Hydrocarbon Fluid Characterization on Wax Precipitation Modeling

Modeling High-Pressure Wax Formation in Petroleum Fluids

A procedure is presented for the simultaneous prediction of fluid–fluid and solid–fluid equilibrium of light gases/heavy hydrocarbons systems under pressure. The objective of this work is to simplify the predictive approach previously proposed by the authors, making it more useful and accessible to users at the petroleum industry. The main modification with respect to the complex LCVM (linear c...
