Calculation method for desulfurization of flare gas
Thread Content
The hydrogen sulfide content in the flare gas is 250,000 PPM, with 3 tons of this gas passing through the flare gas desulfurization tower per hour. How many tons of 20% methyl diethanolamine solution are required per hour to reduce the hydrogen sulfide level to around 200 PPM? How is it calculated specifically? Thank you!

It depends on the type of tower used; calculations are carried out based on the hydraulics of the tower. Specifically, this can be entrusted to a design institute or a tower tray manufacturer for calculation.
Around 30 t/h; since H2S removal from amine solution generally involves complete absorption, it is sufficient to calculate only the acidic gas load on the amine solution during calculations. The H2S content in the lean liquid is generally around 2 g/l, while that in the rich liquid can reach over 20 g/l. Consider adding a margin for safety; you can calculate it yourself. I’m upgrading; don’t forget to give me points. Hehe. This post was last edited by lyybjgz on 2009-3-12 13:05.]
Just asking out of curiosity – what is the answer to the question in the original post? Thank you
