Abstract:
This paper presents a liquid-quench based sampling system applied for the characterization of gas streams in biomass gasification plants and development units. This is a simple, reliable and robust system that allows simultaneous time-resolved measurements of condensable (water, tars, sulfur containing tars, etc.) and non condensable (H2, CO, CO2, CH4, C2H4, etc.) compounds in the sampled gas. Firstly, the principle of operation of the liquid quench based system is presented, secondly the quality of the measurements it allows is evaluated, and thirdly it is shown that the sampling system can be tuned for measurements of trace condensable species in the sampled gas. The influence of the operating parameters gas flow, quenching liquid flow, and cooling temperature is analyzed. Experimental results indicate that the influence of the sampling system can be minimized depending on the compounds to be measured. A compromise is found that allows good quality simultaneous measurements.
