Wax Modeling from Nature

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...

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...

THE NATURE OF MODELING by

Modeling is one of the most fundamental processes of the human mind. Yet it is often misunderstood in ways that seriously limit our ability to function coherently and effectively in the world. The use of inappropriate models (or the inappropriate use of modeling itself) is responsible for countless disasters of personal, technological, and historical proportions. Modeling is the quintessential ...

Release from or through a wax matrix system. II. Basic properties of release from or through the wax matrix layer.

In order to examine basic properties of release from and through wax matrix layer, reservoir device matrix tablet was prepared from a physical mixture of hydrogenated caster oil and drug that was the same one in the reservoir. Release process could be divided into two stages. The first stage was the formation process of water channel by dissolving the drug in the wax matrix layer, and dissolved...
