Demonstration of time-varying solvent regeneration and variable ramp rate

This study will investigate the feasibility of flexible operation in post-combustion CO₂ capture plants by demonstrating two novel approaches to operation. The time-varying solvent regeneration scenario demonstrates the ability to store CO₂ within the working solvent. Secondly, the variable ramp rate scenario investigates the ability to ramp process parameters at different rates (at constant liquid to gas ratio, L/G) whilst still being able to maintain a constant degree of CO₂ capture (i.e., the same CO₂ capture rate).
