Emission of carbon dioxide (CO2) and its negative effect on the climate has gained much attention lately. One of the available technologies for capture of post-combustion CO2 involves use of monoethylamine. The figure below shows a schematic of an absorption tower used to capture CO2 emitted in a power plant. a) Identify 3 controlled variables, manipulated and disturbance variables for this process. Note that the Amine flows are liquid whereas the Gas and Emissions flows are vapor phase. b) Conceptually design a feedback control system for this process. b) Conceptually design a feedback control system for this process
