Seeking advice on the selection of thermodynamic equations
Thread Content
In Aspen, for mixtures that contain both water, hydrocarbons, and alcohols, what thermodynamic equation should be used to simulate flashing in both gas and liquid phases? More specifically, a stream of material in gas form, containing about 70% water, about 30% hydrocarbons, and about 1% alkyd, enters a separation vessel (where a gas-liquid equilibrium process takes place for separation); the temperature in this separation vessel is lower than that of the material stream. In this simulation, which thermodynamic equation is more appropriate to choose?

It seems like you are calculating the separation process that follows the production of olefins from methanol. I have been working on this calculation, trying out N different equations for describing physical properties, but none of them seem to give satisfactory results. So far, Unifac seems to be the closest in terms of prediction accuracy, but there is still a discrepancy! ! ! ! ! ! Please ask an expert for guidance! ! ! !
