Investigation of the Dynamic Behavior and Control Strategies for a CO2 Capture System Using Amine Solution
摘要
Abstract
The amine-based CO2 capture system is an inherently dynamic system that is affected by the load variations in the up-stream power plant due to fluctuations in electricity demand. However, most of researches in this field are based on the steady state operation model, little dynamic data and analysis of the dynamic behavior of a CO2 capture system are available in open literatures. A dynamic model of amine-based CO2 capture system was developed with Aspen Dynamics software based on a typical coal fired power plant. Dynamic responses of the amine-based CO2 capture system with basic control structure were studied when step change in reboiler heat duty, flue gas flowrate and CO2 composition. The results show that the CO2 removal efficiency is influenced by the flue gas disturbances. The CO2 removal target is guaranteed by two proportional control strategies, and operating parameters can be adjusted according to the changes of the flowrate and CO2 composition in flue gas. Dynamic simulations show that the CO2 capture system can achieve removal targets with the proposed control strategies.关键词
