Abstract:
1. A method for predicting onset of liquid phase to solid phase transition of a mixture including a plurality of fatty acid methyl esters (FAME) components, the FAME components are subdivided into a plurality of groups, comprising: identifying chemical and molecular structure of each component of the mixture using data collected with a mass spectrometer and using a computing device containing a library of information of the chemical and molecular structure of each component; calculating, using the computing device, activity coefficients for each component in a solid phase and a liquid phase according to wherein: calculating, using the computing device, chemical potential (μ) for each component in the liquid phase (L) and in the solid phase (S) at a predetermined temperature (T) and a predetermined pressure (P) according to μ μ R is the ideal gas constant; γ χ μ μ γ χ calculating, using the computing device, the cloud point of the mixture, wherein the cloud point is used to characterize cold flow properties of FAME, according to wherein Q wherein Q wherein group shape parameters δ
