Selection of property calculation methods for the Aspen simulator in the methanol amination process
Thread Content
In the methanol amination system, which includes monomethylamine, dimethylamine, trimethylamine, methanol, ammonia, etc., several thermodynamic models were tried in Aspen simulations, but none were able to accurately simulate the azeotropy conditions of trimethylamine with monomethylamine, dimethylamine, and ammonia respectively. Could you advise which property method is more suitable, or is it the case that Aspen lacks some vapor-liquid equilibrium parameters for the methylamine system?
Does the original poster have any experience? I look forward to discussing what is suitable for choosing physical property methods
