A generalized thermodynamic model was developed based on continuous thermodynamic phase equilibria employing two-parameter (, ) gamma distribution function with a generalized correlation to split and characterize the lumped fraction. New Molecular Weight (MW)-dependent thermodynamic property correlations were developed and used to calculate the solid-liquid-equilibrium-ratios (KiS-L). The model was validated with data obtained from experiments conducted on 32 different hydrocarbon fluids from the Niger Delta, North Sea, Gulf of Mexico, East Asia, and Middle East fields. The model for wellbore...
