In this study, a synthetic amine made using the ethylene oxide-
ammonia reaction was used as an absorbent to remove carbon dioxide.
Existing absorbents were used in a mix in order to improve performance; however,
because the ethylene oxide-ammonia reaction generates primary, secondary,
and tertiary amines simultaneously, it has the merit that separate mixing of
the absorbents was not needed. The performance of carbon dioxide absorption
with the synthetic amine was compared to that of MEA. As a result of an experiment,
it was determined that the CO2 loading was 1.15 times better than that of
MEA (a commonly used amine), while the cyclic capacity was 2.28 times higher.
Because the heat of reaction was 1.10 times lower than for MEA, the synthetic
amine showed superior performance in terms of absorption and regeneration.
