Coal based power plants using oxy-combustion for CO2 capture: Pressurized coal combustion to reduce capture penalty

Enthalpy Calculation for Pressurized Oxy-coal Combustion

Oxy-fuel combustion is recognized one of the most promising available technologies that zero emission accomplishment may be in the offing. With coal burned under the pressure of 6MPa and oxygenenriched conditions, the high temperature and high pressure gaseous combustion product is composed of 95% CO2 and water-vapor, with the rest of O2, N2 and so on. However, once lauded as classic approach o...

Process Integration in Coal based Oxy-Combustion Power Plants

The oxy-combustion technology is ready for demonstration [1]. However, the energy penalty and investment cost related to CO2 capture are still too high to implement this technology in the power industry. The thermal efficiency penalty is currently around 10% points, and as discussed in [2] it is commonly expected to be reduced to below 6% points in the near future. Improvements on the sub-units...

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...
