Selective amines absorb H2S in the presence of CO2, either from thermodynamic solubility or kinetic effects. Mixtures containing selective amines can be formulated to allow a certain amount of CO2 to remain in the processed gas. Units designed with selective amines often have little margin for error with respect to plant capacity. Unfortunately, increases in the acid gas concentration or increases in throughput exceeding design can result in sweet gas which does not meet the CO2 specification. Since adding additional equipment can be very expensive, variables such as increasing the amine concentration, using mixtures of amines, and varying the lean amine temperature affect amine sweetening were studied. These variables require little or no additional capital expenditure relative to other alternatives such as adding reboiler area or pumping capacity UR - http://www.bre.com/technicalpapers/technicalpaper.asp?articlenumber=50 ER -
