Regarding the use of multiple stages of circulating reflux in a distillation column, which of the following statements is incorrect? ( ) A. Setting up reflux between two side streams can reduce the load on the top reflux. B. In addition to removing excess heat, each stage of reflux also serves to control the quality of the product. C. Since the temperature of the slurry in circulation is high, to improve heat utilization, it is better to extract as much heat from the slurry as possible. D. Using top reflux can reduce the cooling load at the top of the column compared to using cold reflux
C. The temperature of the slurry circulation is high; to improve heat utilization, it is better to extract as much heat from the slurry as possible
