Optimization of MEA based post combustion CO2 capture process: Flowsheeting and energetic integration

Control of a post-combustion CO2 capture plant during process start-up and load variations

Dynamic and flexible operation of a carbon capture plant is important as thermal power plants must be operated very flexibly to accommodate large shares of intermittent energy sources such as wind and solar energy. To facilitate such operation, dynamic models for simulation, optimization and control system design are crucial. In this paper, we present a dynamic mathematical model for the absorp...

Water Vapor Adsorption on Biomass Based Carbons under Post-Combustion CO2 Capture Conditions: Effect of Post-Treatment

Process Design of Aqueous Ammonia - based Post - combustion CO 2 Capture

In the present work, the aqueous ammonia-based post-combustion CO2 capture (PCC) process is simulated using the rate-based model in Aspen Plus, by which the method of sizing column heights is revealed. The heights of the staged CO2 absorbers and the NH3 absorber are determined as 5 m, 6 m, and 6 m; in addition, the heights of the CO2 and NH3 strippers are 12 m and 6 m, respectively. It is well ...

Capital Costs and Energy Considerations of Different Alternative Stripper Configurations for Post Combustion Co2 Capture

Capturing and storing the greenhouse gas carbon dioxide (CO2) produced by power plants and factories before it is emitted to the atmosphere could play a major role in minimizing climate change. Among of the different technologies, aqueous amine absorption/stripping is a promising one. In this study 5 different configurations for aqueous absorption/stripping have been compared with regard to cap...

Wet impregnation of a commercial low cost silica using DETA for a fast post-combustion CO2 capture process

This work presents an economic and simple method to manufacture low cost, but effective adsorbents for CO2 capture through impregnating DETA to a low cost, porous silica gel. The results have demonstrated that the low cost silica gel impregnated by low molecular-weight amine is stable and work very well at a temperature up to 130 C. The developed adsorbent has a fast adsorption kinetics and can...
