Continuous bottom temperature control for isopropanol
Thread Content
I’m seeking advice from experts: what should be the temperature in the bottom of the continuous column for isopropanol, and what are the appropriate temperature ranges for the middle and lower sections? What are the things to keep in mind?
The waste liquid contains isopropyl alcohol, water, sodium hydroxide, large amounts of protein, and other impurities
The control of the temperature at the bottom of the isopropanol column depends on what substance is present in that bottom section of the column – whether it is a concentration column or a recovery column – as well as on what substances are involved in the azeotrope formation at the bottom of the column.
It is a recovery tower; the azeotropic medium is water
That is, isopropanol rises upward; it should be a triple azeotrope, and there should also be other components present. Depending on the azeotrope temperature, the recovery liquid is extracted at different points.
