[Production Version] Daily Question 2018-2-9 (Short Answer)
Thread Content
Short answer: What are the reasons for the excessive alcohol content in the alcohol-containing wastewater at the bottom of an atmospheric pressure tower, and how is it treated? Reason: Incomplete extraction, low heat load or pressure in the reboiler, high top pressure of the tower, and high liquid level at the bottom of the tower. Treatment: Increase production based on tower equilibrium ； Increase the heat load and pressure of the reboiler ； Reduce the top pressure of the tower ； Lower and control the bottom liquid level of the tower.

Reason: Incomplete extraction, low heat load or pressure in the reboiler, high top pressure of the tower, and high liquid level at the bottom of the tower. Treatment: Increase production based on tower equilibrium ； Increase the heat load and pressure of the reboiler ； Reduce the top pressure of the tower ； Lower and control the bottom liquid level of the tower.
Reason: Incomplete extraction, low heat load or pressure in the reboiler, high top pressure of the tower, and high liquid level at the bottom of the tower. Treatment: Increase production based on tower equilibrium; raise the heat load and pressure of the reboiler ； Reduce the top pressure of the tower ； Lower and control the bottom liquid level of the tower.
Reason: ① Incomplete extraction； ②The reboiler has a low heat load or low pressure ； ③The pressure at the top of the tower is too high ； ④The liquid level at the bottom of the tower is too high ； Treatment: ① Increase the production rate on the basis of tower equilibrium ； ②Appropriately increase the reboiler heat load or pressure ； ③Appropriately reduce the top pressure of the tower ； ④Lower and control the liquid level at the bottom of the tower properly ；
