Mixed gas sorption of CO2/CH4 in TZ-PIM (PIM containing tetrazole unit) was characterized at three different temperatures 25°C, 35°C and 50°C and three molar fraction of CO2, 11.3% CO2, 30.7% CO2 and 50.3% CO2 up to a pressure of 35 atm. Pressure decay equipped with gas chromatograph was used for the experiment. Solubility selectivity of TZ-PIM for CO2/CH4 mixture is higher than solubility selectivity of PIM-1. This is due to the tetrazole group which improves the solubility of CO2 while leaving unaffected the solubility of CH4. Solubility coefficient for both gases decreases with increasing temperature.

Abstract

Mixed gas sorption of CO2/CH4 in TZ-PIM (PIM containing tetrazole unit) was characterized at three different temperatures 25°C, 35°C and 50°C and three molar fraction of CO2, 11.3% CO2, 30.7% CO2 and 50.3% CO2 up to a pressure of 35 atm. Pressure decay equipped with gas chromatograph was used for the experiment. Solubility selectivity of TZ-PIM for CO2/CH4 mixture is higher than solubility selectivity of PIM-1. This is due to the tetrazole group which improves the solubility of CO2 while leaving unaffected the solubility of CH4. Solubility coefficient for both gases decreases with increasing temperature.
