The Hysys tower does not converge
Thread Content
Ethylbenzene styrene separation column, not converging, seeking help. . . .
Attempts can be made to modify the regulations, such as product quality.
Even after modifying the specifications for the key components at the top and bottom of the tower, convergence was not achieved; in fact, the performance worsened further
Generally, defining the product flow rate is not good. How about defining the component content at the bottom of the tower and the temperature at the top condenser?
Previously, I would first define the top of tower flow rate to allow it to converge before making adjustments; this time, however, it won’t converge no matter what, mainly because the difference in values isn’t that large
This tower is not complex; try using boiling point temperature～top vapor concentration or boiling load～top vapor concentration
Solved; just try a few more variables
