Reflux ratio issues occur in the simulation of the atmospheric pressure column for methanol distillation
Thread Content
An error occurred during the calculation of the atmospheric pressure column for methanol distillation. Does anyone know what to do? ** THE ERROR MINIMUM REFLUX RATIO CALCULATED FROM THE UNDERWOOD EQUATION IS -1.0877. THE REFLUX RATIO HAS BEEN RESET TO 0.1.
The error message indicates that the minimum reflux ratio calculated using the Underwood equation is negative (-1.0877), which is unreasonable. The system automatically resets the reflux specific gravity to 0.1. This usually means there may be an issue with the original input parameters. It is recommended to check whether parameters such as the number of trays, feed composition, and specifications of the top and bottom products are set correctly, to ensure the accuracy and validity of all input data. At the same time, it is also possible to try adjusting the reflux ratio and observing the system’s response in order to find more suitable operating conditions. .
