Figure TS.4. (a) CO₂ post-combustion capture at a plant in Malaysia

This plant employs a chemical absorption process to separate 0.2 MtCO₂ per year from the flue gas stream of a gas-fired power plant for urea production (Courtesy of Mitsubishi Heavy Industries). (b) CO₂ precombustioncapture at a coal gasification plant in North Dakota, USA. This plant employs a physical solvent process to separate 3.3 MtCO₂ per year from a gas stream to produce synthetic natural gas. Part of the captured CO₂ is used for an EOR project in Canada.
