- Different methods of introducing CO2 to a heterogeneous mixture of water and 1-cyclohexylpiperidine are explored in order to generate a single-phase aqueous 1-cyclohexylpiperidinium bicarbonate solution. Membrane gas contacting was found to be an effective method for CO2 addition. This analysis varied solution temperature, gas pressure, solution pressure, solution flow rate, and membrane area to determine and minimize mass transport and chemical reaction limiting phenomena. Both mass transport limitations and chemical kinetic limitations were found for the industrially relevant membrane gas contacting process conditions explored in this study.
