One question on distillation operations
Thread Content
During distillation, if the composition, flow rate, and vaporization rate of the feed remain constant, increasing the reflux ratio will result in an increase in the slope of the operating line for the distillation section (), an increase in the slope of the operating line for the stripping section (), an increase in the composition at the tower top (), and an increase in the composition at the tower bottom (). A: Increase ； Reduce ； Increase ； Reduce B: Decrease ； Reduce ； Increase ； Reduce C: Increase ； Reduce ； Reduce ； Reduce D: Increase ； Reduce ； Increase ； Increase
Why? I hope an answer can be given
A: Increase； Reduce ； Increase ； Reduce
