THE FLASH CALCULATIONS FAILED TO CONVERGE AFTER 23 ITERATIONS. THE BUBBLE POINT CALCULATION HAS REDUCED THE TEMPERATURE TO THE LOWER LIMIT OF 91.7630 K. THE BUBBLE POINT TEMPERATURE CANNOT BE ESTIMATED AT THE SPECIFIED PRESSURE. THE FLASH PROCESS FOR THE DISTILLED LIQUID FAILED. THE BLOCK WAS BYPASSED. What is the reason for this issue in distillation?

There is non-condensable gas at the top of the tower; increasing pressure, using a demister, and so on. . .

Hello, I’m facing a similar problem with my deethanizer tower. Could you tell me how you resolved it?
