... of real components. Thus, an exact feed composition is not known. The most common method to overcome this difficulty is to define pseudo-components based on one or more physical properties such as boiling point or molecular weight. In this work, we propose a set of model thermal cracking reactions based...

..., has a significant impact on MMP in that the MMP increases with the increase in oil molecular weight. A high oil volatiles fraction (e.g., C1) in the reservoir oil causes the MMP to rise; whereas, a high intermediates (C2-C4) PETROLEUM SOCIETY CANADIAN INSTITUTE OF MINING, METALLURGY & PETROLEUM...

... of asphaltene precipitation during solvent titration in heavy oil. At the second stage the Flory-Huggins (FH) model is modified by three adjustable parameters (a, b, c) to predict asphaltene precipitation more accurately. These parameters are defined based on molecular weight of asphaltene to molecular weight...
