For a biomass gasification process, the removal of sulfur dioxide (SO2) and hydrogen sulfide (H2S) from the dirty producer gas is considered to be relatively easy (e.g. by scrubbing); however, the removal of carbonyl sulfide (COS) is more difficult. To help with the development of a suitable gas clean-up strategy, the presence of COS species was considered in more detail in this study by both experimental measurements and theoretical thermodynamic equilibrium calculations.
The results indicated that the theoretical thermodynamic equilibrium calculation showed a good match with experimental data, when equilibrium temperature of over 900oC was assumed. It is interesting to note that the temperature of over 900oC was also the highest temperature observed in the hot zone of gasification experiments.
