DSTWU simulated gas distillation

2019-11-10View Original

Thread Content

I’m facing the following issues while simulating gas distillation and don’t know how to solve them; please help! ! ! ! ! ! SEVERE ERROR DURING THE POST-SOLVE STAGE OF UNIT OPERATIONS BLOCK: \"1\" (MODEL: \"DSTWU\") (UDL01.14). The K-VALUE of the light key component in the distillate is 0.80935E-17 at a distillate temperature of 6.9288. It is not possible to calculate the minimum number of stages; therefore, the calculations have been skipped.

It is recommended to describe the problem in detail or upload a simulation file

The K value of the light key component is too low. Should the file be uploaded?
