Gas scrubbing technologies

=Liquid Solvents=

Econamine FG

 * Monoethanolamine (MEA)
 * Established technology used for CO2 recovery
 * Low tolerance for SOX and NOX
 * Degrades in the presence of O and CO
 * Cost $28/tonne of CO2 recovered
 * Energy penalties of 10%

Selexol Process

 * Dimethyl ether of polyethylene
 * Predominately used for removal of sulpher compunds
 * Possible to co-absorb CO2
 * Pre-combustion removal of sulphers and decarbonisation in IGCC

Fluor Process

 * Propylene carbonate
 * Predominately used for removal of sulpher compunds
 * Possible to co-absorb CO2
 * Pre-combustion removal of sulphers and decarbonisation in IGCC

Sulfolane

 * Tetrahydrothiophene dioxide

Morphysorb Process

 * Direct competitor with Selexol
 * 95% wt solution of N-acetyl morpholine (NAM) and N-formyl morpholine (NFM)
 * NAM to NFM ration kept at 1.5
 * Pre-combustion technology, ie IGCC
 * Unsuited to post-combustion as it would require the cooling of flue gases to ambient
