Density calculations within Chemsep/COCO
Posted: 25 November 2020, 15:53I use a Chemsep Prop Pack within COFE.
and userdefined physical properties within Chemsep.
When setting liquid component density to temperature correlation
and mixture liquid density to Costald, it gives correct pure component densities for water and methanol
and slightly incorrect mixture densities within COFE.
When changing mixture liquid density to Racket (DIPPR) it gives quite incorrect pure component density for water (7% above "true" value),
despite pure component density is still set to temperature correlation and temperature correlation
for water is correctly implemented within Chemsep.
How can that be? Is that a bug?
