Natural gas is used mainly as a fuel and also as a raw material for petrochemical industry. It is regarded as an environmentally friendly clean fuel compared to other fossil fuel. However, the presence of carbon dioxide, CO2 gas lowers the fuel value of natural gas and therefore need to be removed. The most commonly used technique to remove CO2 is by chemically absorbing CO2 with aqueous alkanolamines. However, there are some disadvantages of the current process in such that the aqueous solution will undergo degradation, the enthalpy of reaction for the chemical absorption of CO2 is high in addition to corrosion and fouling problems of the process. Currently, ionic liquids are under intense investigation as a potential replacement for solvents in reaction and separation processes. In the separation of CO2 from natural gas, ionic liquids are being proposed as potential solvents to absorb CO2. To date, several ionic liquids, mostly imidazolium-based ionic liquids were successfully applied in absorbing CO2 under experimental conditions. In this work, lower cost of ionic liquids from a different class of cation namely pyridinium based, were synthesized and characterized. The low pressure solubility of CO2 in these ionic liquids was determined using a Magnetic Suspension Balance (MSB) equipment at temperatures of 298.15K, 313.15K and 333.15K and pressure range of (0.99 - 12.53) bar. The effect of using different cation's alkyl chain length was also presented. The CO2 solubility results were compared with published data obtained from literature using imidazolium based ionic liquids. Additionally, the solubility of methane, CH4 and nitrogen, N2 in these ionic liquids at 298.15K and pressure of (1.00 - 10.03) bar were also measured and compared with that of CO2. Results show that the pyridinium based ionic liquids have potential to be used as solvents to remove CO2 from natural gas.
