Optimization of an Existing 130 Tonne per Day CO2 Capture Plant from a Flue Gas Slipstream of a Coal Power Plant

An optimization study has been conducted on an existing 130 tonne per day carbon dioxide capture plant. A rate-based modelling approach is used to simulate the performance of the CO2 capture plant using actual plant process flow-sheet and operating parameters. The average absolute deviation of the predicted parameters from the measured parameters is within 8%. The developed rate-based model is then used to plan the operating conditions for optimum utilization of the resources. Based on the results obtained from the process optimization, it is possible to minimize the operating cost and enhance the production capacity of the CO2 capture plant at minimum additional investment.
