Hi everyone Im an undergraduate petroleum engineering student. As one of our projects, weve been tasked to design an absorption tower for H2S removal. I was given the basis of Vented gases containing 35% H2S flow at a combined flow rate of 60 m3/ hr at temperature of 60°C and 1 ATM pressure. The tower needs to reduce the concentration of H2S gas to less than 7 ppm prior to discharge to atmosphere
I was thinking of using Monoethanolamine for the absorbent. however i cant find any equilibrium data that might help me get started. Im also at a loss at how to deal with absorption processes with chem reactions. can i treat this like any other physical absorption? Also this is a non dilute problem and i need to reduce the conc of H2S to an insignificant level. Should I do a reflux to lower the inlet conc.?
If someone could point me to the right direction as to how to approach this design, Id really appreciate it. Thank you all.
