【Daily Question No. 69】On June 1, 2021, the pressure drop in the distillation column increased, indicating an increase in the column’s load. True or False ( ) Please reply within two days.
Error. Analysis: The reasons for the increase in distillation column pressure drop are as follows: 1. Poor control of the heating energy at the bottom of the column; excessive heating energy leads to an increased amount of vapor produced, thereby raising the column pressure. 2. Influence of the feed’s thermal state. 3. The amount of refrigerant used at the tower top is small, resulting in less reflux being recovered from the tower top. 4. Instrument failure. 5. Abnormal operation. 6. Tower blockage. It is necessary to identify the cause in order to prescribe the right treatment.
