Hybrid Solvents

Hybrid solvents go beyond using just aqueous amines for gas treating.  This type of solution has an organic component added into  the aqueous amine mixture.  One of the advantages is that certain components to be removed from the gas have very low water solubility, making them hard to dissolve, but the organic part of the solvent has very high solubility for these same components.  Yet the aqueous amine content, albeit with a lower water concentration, still has very high solubility for the acid gases.  Hybrid solvents offer a way to tailor the solvent to exhibit better characteristics for removing both acid gases and trace sulfur components such as mercaptans and COS.  Learn more about how this is done and the effect of the technology by further reading here and here.
