Analysis of Various Flow Schemes for Sweetening with Amines
There are many possible process variations for sweetening sour hydrocarbons with amines. Those to which we have given attention include the use of precontactors (static or jet eductor mixers), multiple absorber inlet nozzles, split flow units and pressure swing regeneration. Each of these variations is best suited to a certain set of operating conditions. Not all processes are appropriate for use with certain feed compositions or product requirements. This paper will discuss the application of the various flow scheme alternatives to a variety of different process conditions.
