Abstract

Carbon dioxide is one of the major green house gases.
It
is removed from different streams using amine absorption process.
Sterically hindered amines are suggested as good CO
2
absorbers.
Sol
ubility of carbon dioxide (CO
2
) was measured in aqueous
solu
tions of 2-Amino-2-methyl-1-propanol (AMP) at temperatures 30
o
C, 40
o
C and 60
o
C. The effect of pressure and temperature was
stu d
ied over various concentrations of AMP. It has been found that
pressure has positive effect on CO
2
solubility where as solubility
dec
reased with increasing temperature. Absorption performance of
AMP increased with increasing pressure. Solubility of aqueous AMP
was compared with mo-ethanolamine (MEA) and the absorption
capacity of aqueous solutions of AMP was found to be better.
