CCS – Carbon Capture and Storage general CO2 cycle: 1) capture (separete, concentrate, compress) – at power unit 2) transport – 3) storage – 3) use – out of power unit http://thewere42.wordpress.com/2009/07/13/carbon-capture-and-storage-progressing-toward- feasibility

CCS – CO 2 Capture • Depleted/mined oil fields • Depleted/mined gas fields • exploitable coal seams • saline aquifers http://papundits.files.wordpress.com/2009/10/ccs-03.jpg

Basic ideas of CO2 capture Postcombustion (after air combustion) = CO2 capture from fmue gases after fuel-air combustion in typical fossil power plant Oxyfuel (oxyfuel combustion) (oxy-combustion, oxy-fjring, oxy-fuel a denitrogenation) Precombustion (before combustion) = removing CO2 from fossil fuels before combustion Chemical looping (chemical looping; by any of the preceding ideas)

CCS – POSTCOMBUSTION Air combustion – CO 2 capture from fmue gases S. Santos - GHGT10 Student Mentorship, www.jeaghg.org

CCS – POSTCOMBUSTION, methods Absorption process – physical and chemical = liquid absorbent srubbing (solvent or chemical reagent) Adsorption process – physical and chemical = adsorption on solid surface (physical sorbent – active carbon, molecular sieves etc.) (chemical bond – CaO, NaOH a others) Physical separation process (membrane, cryogenic etc.) Biological detection – photosynthesis (algae, enzymes, nanoparticles) Others methods (electrochemical)

CCS - OXYFUEL Oxygen combustion Santos - GHGT10 Student Mentorship, www.jeaghg.org

CCS - PRECOMBUSTION Fuel gasifjcation – shift reaction - CO 2 Capture/Separation S. Santos - GHGT10 Student Mentorship, www.jeaghg.org
