IPCC Report – Carbon Capture and Storage – www.ipcc.ch
Coal fired power stations – 750 g/kWh
A 1 GW plant:
Emits >750 tonnes per hour of CO2
Approx 1/90 of full scale for 1 GW
Costs > £1 Billion
Uses 40% of the energy if installed as a “plug and play”, 25-30% with R&D.
Carbon capture – amines
CO2 capture plant in Malaysia, using a 200 tonne d-1
KEPCO/MHI chemical solvent process (c. Misubishi)
Retrofit of Amine Process into a Coal-fired Power Plant
Required reboiler duty [MJ/kgCO2] : Base case (3.54) > Case 1 (3.39) > Case 2 (3.35) > Case 3 (3.11)
Design basis• Subcritical coal-fired power plant with bituminous coal.
• Solvent : 30wt% aqueous MEA.
• 90% CO2 capture, constant heat input to the power
plant, CO2 compression up to 150 bar.
• Reboiler steam from the extraction of IP/LP crossover in
the steam cycle.
• Unisim R390.
• Power plant efficiency drop by retrofit : 8–10%.
Amine process scheme study
Case 1 : absorber intercooling Case 2 : absorber intercooling & water spray Case 3: split-amine flow
Semi-lean amine
Lean amine
• A good current adsorbent @ 0.1 bar – CO2 capacity 10 % w/w
• Allow for improvement – CO2 capacity 20 % w/w
– Assume bulk density 800 kg/m3
– Assume column diameter 4 m
• Typical Temperature Swing Adsorption cycle
– 2 hours
– 15000 tonnes of adsorbent
– Adsorbent bed length 1.5 km (cumulative)
• Typical Pressure/Vacuum Swing Adsorption cycle– 2 minutes– 250 tonnes of adsorbent– Adsorbent bed length 250 m (cumulative)
Why need innovation?Estimates for 1 GW
• CO2 capture will require a significant improvement in the adsorbents.
• CO2 capture will require a step change in the engineering of adsorption cycles– VSA Cycle times < 10-20 seconds.
• Existing simulation codes will NOT predict process dynamics reliably!
• Will need experimental techniques for testing novel materials.
• Target : The energy consumption of an adsorption process should be less than half of that of MEA process.
Why need innovation?Adsorption

The Innovative Gas Separation for Carbon Capture (IGSCC) Project
Aims
• Apply a range of experimental techniques to determine equilibrium and kinetic
properties of nanoporous materials, which are being developed for CO2 capture.
• Develop detailed simulations of membrane and adsorption units that will be used
for parameter estimation and process optimization in the integration of carbon
capture in power plants
Materials
Thanks to this broad collaboration a wide range of materials can be tested:
• PIMs (University of Manchester, Cardiff University)
• BPL Carbon (University of Manchester, Cardiff University, UCL)
