Effect of the Tower Type on the Gas Sweetening Process
The removal of acid gases, CO2 and H2S from natural gas streams is essential for environmental and health reasons. In this work, the simulated gas sweetening unit with Methyl-DiEthanolAmine (MDEA) solvent was studied to improve quality. Firstly, the effect of trays types and then, the effect of vari...
