Dear All,

I am trying to sperate two compnonets using DSTWU COLUMN in Aspen Plus, I got the error shown below.

SEVERE ERROR IN PHYSICAL PROPERTY SYSTEM
WATSON HEAT OF VAPORIZATION MODEL HAS MISSING PARAMETERS:

DHVLWT/1ST ELEMENT (DATA SET 1) MISSING FOR COMPONENT PBR3

DHVLWT/2ND ELEMENT (DATA SET 1) MISSING FOR COMPONENT PBR3

****PROPERTY PARAMETER ERROR
ERRORS ENCOUNTERED IN CALCULATION OF LIQUID MIXTURE MOLAR ENTHALPY USING
OPTION SET NRTL-RK FOR H

After getting this error I added enthalpy of vaporization for PBR3 in pure component data , still getting same error. Please help me how to solve this error.

Thanks,
Nageswar Reddy

Hi!

I am also getting this error when I work with a mixture of benzene, water and NaOH... The problem is with the NaOH... did you manage to solve this issue?

Thanks!
