Help~ Estimating physical properties with ASPEN PLUS
Thread Content
I’m a beginner who wants to estimate the physical properties of a 50% urea aqueous solution; I keep getting errors. The message reads: “Table Generation begins... VAPOR PRESSURE MODEL PL0XANT HAS MISSING PARAMETERS: PLXANT/1ST ELEMENT (DATA SET 1) IS MISSING FOR COMPONENT UREA. **** PROPERTY PARAMETER ERRORS WAS ENCOUNTERED DURING THE CALCULATION OF VAPOR-LIQUID K-VALUES USING THE NRTL-RK OPTION SET FOR KVL. ! Calculations were stopped due to missing property parameters.” Could someone help me estimate the viscosity (in cP) and specific heat at normal pressure at 50°C, as well as at 4.5 bar and 145°C? It would be great if you could give some guidance
Check the book; I remember it’s in the \"Manual for the Process Design of Nitrogen Fertilizers – Urea\"
