This document summarizes a new gas treating technology using glycerol derivatives as solvents. The technology utilizes glycerol derivatives that have lower viscosity than current solvents, making them suitable for use in hollow fiber membrane contactors. The glycerol derivatives selectively absorb contaminants like CO2 and H2S from gas streams while allowing CH4 to pass through. This new solvent performs better than existing Selexol solvents and can be recycled. The hollow fiber membrane contactor provides advantages over conventional gas scrubbing like lower capital and operating costs due to its compact size and ability to achieve mass transfer without fluid dispersion.
