Project design and control considerations on gas sweetening processes

Amine plants for gas treatment are well-known processes to remove a series of compounds either upstream some plant operations particularly sensitive to these chemical species or before sending to vent/stack a process stream so as to match environmental regulations. There is a long experience in the design of amine plants and in their typical configuration of energy integrated absorber and stripper. Nevertheless, the design and the unit operations of current amine processes directly come from feasibility studies based on steady-state simulations and a series of process control considerations can be pointed out by means of the process dynamic simulation.
