general CO2 cycle: 1) capture (separete, concentrate, compress) – at power unit 2) transport – 3) storage – 3) use – out of power unit

CCS – CO2 Capture

SLIDE 4

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)

Basic ideas of CO2 capture

SLIDE 5

Air combustion – CO2 capture from fmue gases

S. Santos - GHGT10 Student Mentorship, www.jeaghg.org

CCS – POSTCOMBUSTION

SLIDE 6

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 – POSTCOMBUSTION, methods

SLIDE 7

Oxygen combustion

CCS - OXYFUEL

SLIDE 8

Fuel gasifjcation – shift reaction - CO2 Capture/Separation

S. Santos - GHGT10 Student Mentorship, www.jeaghg.org

CCS - PRECOMBUSTION
