I am a newbie, how can I eliminate the warning in this situation?

The pressure difference is too large and the gas flow rate is too large. Try increasing the tower diameter.

Hello, can I ask about your physical property input? The composition of my raw material nitric acid is: 0.7 nitric acid, 0.01 nitrous acid, 0.0002 potassium sulfate, and the remainder is water. When using elentrl, there are a lot of warnings, and an error is reported when running. The error is as follows: * * * * PROPERTY PARAMETER ERROR ERRORS ENCOUNTERED IN CALCULATION OF VAPOR-LIQUID K-VALUES USING OPTION SET ELECNRTL FOR KVL.
