The Mechanical Section has introduced the \"Question of the Day\" feature, which not only helps to foster an active atmosphere for technical discussions and guide the direction of such exchanges but also provides users with financial rewards, enabling them to experience various cool features. Question content: Multiple-choice question. Which of the following is not a correct method for dealing with high pressure differences in distillation columns? A. Appropriately increase the production rate. B. Appropriately raise the liquid level in the tower bottom. C. While ensuring product quality, appropriately reduce the reflux rate. D. Appropriately lower the reboiling temperature. The correct answer is: B. Some people chose ACD; perhaps they thought those were the correct answers. A high pressure difference indicates a high vapor-liquid load on the tower; both the reflux at the top of the tower and the reboiling at the bottom are high, resulting in less product being extracted. Based on this logic, approach B is incorrect.
