ABSTRACT:
Preferential sulfur dioxide absorption solvents may be buffered with suitable agents, such as alkanolaminium carboxylates, to substantially retard or eliminate the tendency of such solvents to degrade or accumulate non-regenerable salts, particularly sulfates, when loaded with absorbed sulfur dioxide. A method for employing the buffer as an immiscible aqueous phase as a separate trimming solvent to selectively absorb residual sulfur dioxide from a gas stream from which the bulk amount of sulfur dioxide is first removed by contact with a trialkyl phosphate solvent is disclosed. The method permits the trialkyl phosphate solvent to be regenerated and purged of salts at lower energy requirements.
