Q & A > Question Details
We are using 20% DEA for removing H2S from gases in our refinery. How much 1% DEA will remove H2S if Rich amine loading is kept 0.33 mole H2S/Mole DEA for total circulation rate of 220 m3/hr as want to increase DEA Concentration. How can a relationship between Rich Amine Loading & Concentration be established?

At 20% DEA by volume, the 0.33 mols H2S/mol DEA calculates to equal 31,000 mols H2S/ H. Therefore, a 21% DEA solution will remove 32, 550 mols/H of H2S.
