Calculation of tower diameter and packing height of packed tower
Thread Content
In the actual engineering design, the chlorine drying tower (sulfuric acid) calculation, tower diameter and packing height are not clear. I would like to ask my friends for help. 1. When individuals calculate the tower diameter, they first assume a tower diameter and use this to calculate the liquid volume. The horizontal axis value of the "Eckert universal correlation diagram" can be calculated and the vertical axis value is checked. Then a tower diameter is calculated based on 70% of the pan-point gas velocity. Repeat the trial and error. When the assumed pipe diameter is close to the calculated tower diameter, it is sufficient. Is this feasible? Because I saw a calculation example in "Chlor-Alkali Production Technology", which is the liquid spray volume calculated based on the liquid-gas ratio. 2. In the calculation of the packing height, I wanted to use the logarithmic average driving force method to find the number of mass transfer units, but after seeing the calculation examples in "Chlor-Alkali Production Technology", I was a little confused, because when calculating Y1 and Y2, conversion was also performed in the example. I don't know why? In addition, Y * How did you ask for it? In the example, 3.46 is the mass of water in the gas phase entering the tower, and 883.903 is the amount of dry chlorine.

Hello, is it necessary to use fillers? you can find me

Therefore, we should be grateful to those scientists who do basic research work. For chemical absorption, Y * =0
I would like to ask someone, I performed the simulation according to the manual and the attachment has been added. Why did the chlorine gas in the result end up in the liquid phase?
The chlorine gas has gone to the liquid phase, which is wrong. This shows that the thermodynamic method (physical property package) you chose is not suitable for this system.
When I use ELECNRTL, binary interaction parameters are required. How do I find them?
