property package for condensable polar gases
Posted: 19 August 2020, 15:03
Hallo,
I want to model heating and cooling of methanol and water. Temperatures are between 20-240°C, pressures between 2 bar and 20 bar abs.
Cofe/Coco is used for this.
When usinig the TEA property package I obtain significant enthalpy deviations within liquid and vapor phase compared to
enthalpy values from tables such as within VDI heat atlas.
I tried all enthalypy calculation types within TEA and found that the ideal-enthalpy setting produces most accurate enthalpy values.
However, I would like to have it more accurate with deviations less than 10%.
The water property package does work very well for water enthalpies, however, no other compounds and no methanol can be calculated within the same stream when using that package.
Is there another model/option available that is more suitable for the compounds and conditions mentioned above?
Eventually from the Chemsep property package?
