초록

Volatile organic silicon compounds (namely as siloxanes) are impurities in biogas generated from landfill and biogas. They have been known to cause damages to gas combustion engines. However, factors affecting process design decisions have been less studied. In this research, we experimentally determined the gas-liquid partition coefficients (Kp) of siloxanes by applied the equilibrium partition experiment in closed system. we also investigated the effects of liquid solutes on siloxanes partitioning. Five different types of siloxanes and five different types of liquid solutes (distilled water, nutrient solution, ferrous sulfate solution, and surfactant solutions) were selected for this study. Dimensionless gas-liquid partition coefficients of siloxanes were determined to be 8.808 for L2, 2.278 for L3, 1.455 for L4, 3.435 for D4, and 0.770 for D5. Partition coefficients varied by liquid solutes, Especially for surfactants as liquid solutes, mass transfer of siloxanes from gas to liquid was enhanced, showing the lowest coefficients of partitioning.
