For the question about calculating the packing layer in the absorption tower in the afternoon, how do I do it?
Thread Content
It’s still an absorption tower; the inlet gas composition is 0.03, with a removal efficiency of 99%. The liquid phase outlet concentration is 0.013. The value of ka was given, and Y=2X; this value is used to calculate the height of the packing tower.
The original question for this problem can be found in Tianjin University’s complex* tutorial, in the relevant chapter; it’s basically the same
Question 5 in the afternoon of 2010, the type is exactly the same. This problem needs to be solved using mole fractions, not mole ratios.
It is important to note the mole fraction and mole ratio, as stated in the original question by the association
Should it be calculated using molar fractions or molar ratios?
The question asks you to use molar fractions; this is specified in the question. I first tried to calculate using molar ratios, but I didn’t get the correct answer until I realized that molar fractions should be used. There is an answer available, and although the original textbook doesn’t require the use of molar fractions, the answers provided by the association do use them. I thought the answers given by the association were incorrect when I was working on it, but it turns out that this is indeed how the question is meant to be answered – it’s everywhere
In that case from the afternoon, regarding the question about the boiling point increasing by 9 degrees – if those 9 degrees aren’t taken into account, is there still an answer?
Strictly speaking, molar ratios should be used; when the concentrations are low, molar fractions can be used as an approximation
