PROII Calculation Results Challenge

Thread Content

When I enter new substances in the PROII calculations, the program can no longer perform calculations~~~~ I added two new components: sodium nitrate and sodium nitrite~~~ The results shown were as follows: 3 error(s), 0 warning(s), and 0 message(s) detected: *** error *** Liquid thermal conductivity correlation data is required but missing for component 18. *** error *** Transport property methods requiring certain pure component properties are specified, but those properties are not available for some components as listed above. Transport properties are only required for certain transport calculations such as column hydraulics, rate based distillation, rigorous heat exchangers and pipe unit operations. You may turn off transport calculations for this simulation if they are not being used. *** error *** Transport property methods requiring certain pure component properties are specified, but those properties are not available for some components as listed above.
