【Daily Question】Chemical Engineering Principles 189: Distillation (October 1) – Double rewards
Thread Content
The Chemical Engineering Theory section is launching the \"One Question per Day\" campaign starting today, aimed at helping everyone reinforce their basic knowledge in chemical engineering. Subsequent series will include those on \"Principles of Chemical Engineering,\" \"Mass Transfer and Separation,\" \"Thermodynamics in Chemical Engineering,\" and \"Chemical Process Engineering.\" We hope for your active support! Answers to the questions in the \"One Question per Day\" campaign can be viewed directly by replying to the post, and the topic will be closed after 1 day ! Participation earns 3 wealth points, with an additional 3 wealth points for correct answers. Fill-in-the-blank: If the structure of the distillation tower remains unchanged and, during operation, the composition, flow rate, heat conditions of the feed, as well as the flow rate at the top of the tower are kept constant, and only the heat load on the bottom of the tower is reduced, then the composition at the top of the tower will be ______, while the composition at the bottom will be __________. Reduce ； Increase
Then the composition at the top of the tower decreases, while the composition at the bottom of the tower increases
With the distillation column structure remaining unchanged, if, during operation, the composition, flow rate, heat conditions of the feed, and the flow rate at the top of the column are kept constant while only the heat load on the bottom of the column is reduced, then the composition at the top of the column decreases, while the composition at the bottom increases.
With the distillation column structure remaining unchanged, if, during operation, the composition, flow rate, heat conditions of the feed, and the flow rate at the top of the column are kept constant while only the heat load on the bottom of the column is reduced, then the composition at the top of the column decreases, while the composition at the bottom increases.
The composition at the top of the tower will decrease, while the composition at the bottom of the tower will increase
Decrease Increase.................
The structure of the distillation column remains unchanged. If, during operation, the composition, flow rate, heat conditions of the feed, as well as the flow rate at the top of the column are kept constant, and only the heat load on the bottom of the column is reduced, then the composition at the top of the column will __decrease__, while the composition at the bottom of the column will __increase______
If only the heat load at the bottom of the tower is reduced, the composition at the top of the tower decreases while the composition at the bottom increases.
Top of tower x D ___, bottom of tower x W ___. . . . . . . . . . .
