Systems Analysis of Ionic Liquids for Post-combustion CO2 Capture at Coal-fired Power Plants

Systems Analysis of Ionic Liquids for Post-combustion CO2 Capture at Coal-fired Power Plants

The main objective of this study is to investigate the feasibility and costs of ionic liquid (IL)-based CO2 capture systems at pulverized coal-fired (PC) power plants. The IL selected for this assessment is trihexyl(tetradecyl)phosphonium 2-cyanopyrrolide ([P66614][2-CNpyr]), achieving a 1:1 and reversible chemical reaction between [2-CNpyr] and CO2. A multi-stage equilibrium-based modeling fra...

Comparing post-combustion CO2 capture operation at retrofitted coal-fired power plants in the Texas and Great Britain electric grids

This work analyses the carbon dioxide (CO2) capture system operation within the Electric Reliability Council of Texas (ERCOT) and Great Britain (GB) electric grids using a previously developed first-order hourly electricity dispatch and pricing model. The grids are compared in their 2006 configuration with the addition of coal-based CO2 capture retrofits and emissions penalties from 0 to 100 US...

Dynamic modelling of CO 2 absorption for post combustion capture in coal - fired power plants 1

Techno-economic assessment of polymer membrane systems for postcombustion carbon capture at coal-fired power plants.

This study investigates the feasibility of polymer membrane systems for postcombustion carbon dioxide (CO(2)) capture at coal-fired power plants. Using newly developed performance and cost models, our analysis shows that membrane systems configured with multiple stages or steps are capable of meeting capture targets of 90% CO(2) removal efficiency and 95+% product purity. A combined driving for...

Co2 Emission and Carbon Capture for Coal Fired Power Plants in Malaysia and Indonesia

Coal consumption in Malaysia and Indonesia is growing at the rate of 9.7 and 4.7% per year since 2002, respectively. The increase in coal utilization usually tallies fairly well with the increase in CO2 emission. The present study attempts at predicting the emissions of CO2 from coal fired power plants from 2005 until 2020. The paper also analyzes the potential of carbon capture (CC) program as...
