Seeking help regarding the H2S content in the desulfurization rich solution obtained by the MDEA method
Thread Content
Hello everyone. We plan to use MDEA for desulfurization in our shell furnace, at a pressure of around 3.5 MPa. I would like to know what the typical H2S content is in the rich liquid – it might be related to the H2S content in the gas; I estimate it to be between 0.2% and 1%. Those who have experience with this process, please provide an approximate value
The rich liquid level is related to the circulation rate. Furthermore, the gas produced by gasification usually has a complex composition and also contains CO2, making the MDEA method less suitable
Reply 1# yjh-ncpe: The desulfurization process of MDEA should be a cycle of adsorption and regeneration. The sulfur content in MDEA is determined by the load of the unit, but H2s has a fixed saturation level in the MDEA solution.
