Abstract

The presence of high C02 up to 70% in certain natural gas reservoirs has posted huge
challenges in the natural gas purification. Although there are several separation technologies
like amine absorption and cryogenic process, their separation capability is limited to low CO2
in natural gas. Alternative approach to separate high CO2 from natural gas by formation of
CO2 hydrate is being explored in this work. The objectives are to investigate the formation
kinetics of simple and mixed hydrate of carbon dioxide and methane in presence of SDS and
POM and the effect of these promoters at various concentrations. Besides that, this study is
also conducted to investigate the selectivity of the promoters towards CO2 from natural gas
via formation of CO2 hydrates. A laboratory - scale batch reactor is built and operated to
carry out this experimental work. In the experimental work, the formation of carbon dioxide
hydrate in deionized water (18M£2) is investigated at fixed temperature of 275.15 K and
pressure of 20, 25, 30,35 bar respectively. Meanwhile, the formation of methane hydrate in
deionized water (18MQ) is investigated at fixed temperature of 273.15 and pressures of 40,
50, 55, 60, 65 bar, respectively.
