Solubility of Ethylene in the Presence of Hydrogen in Process Solvents under Polymerization Conditions

摘要: The concentration of ethylene in the solvent slurry polymerization process is important as it determines extent reaction, reaction temperature, heat duty, and molecular weight. In present study, gas liquid behavior ethylene, presence absence hydrogen, was studied two solvents namely, hexane Varsol at various pressures temperatures. Solubility increases with increase pressure decreases temperature both solvents. Ethylene solubility carbon number identical conditions. hydrogen strongly influences varsol. compared to its binary solubility, while varsol solubility. A heterogeneous thermodynamic model based on Chao−Seader method adopted for modeli...
