Control of the CO2 Capture Using the Absorption and Stripping System for Improved Performance

The paper presents a new control system configuration for the post combustion CO2 carbon capture process using amines. The control system structure consists in six control loops and has in its core the cascade control strategy. The proposed cascade control system has the desired carbon capture rate...
