The use of amine blends to harness the desirable qualities of the constituent amines in order to reduce operating costs and/or improve product quality is becoming increasingly attractive to operators of alkanolamine-basedgas sweetening units. A number of parameters, all of which have economic implications, can be used to monitor the performance of amine blends. These include absorption rates, equilibrium solubility, corrosion, solution degradation and reclamation. This paper evaluates the influence of blend composition and components on some of the above parameters for aqueous blends of MDEA + MEA, MDEA + DEA and MDEA + DIPA
