||Confined space ventilation: Tracer gas analysis of mixing characteristics

||Study of the mixing effectiveness of dilution ventilation of confined spaces (the hold of petrochemical vessels). The tracer gas sulfur hexafluoride (SF6) was used as an experiment, with an infrared analyzer capable of sampling at 90L/min used as the monitoring instrument, and smoke tubes and anemometry used to assess air circulation. It was found that air in the vessels showed mixing that was much slower than predicted by theory, due to the complicated dynamics of internal air circulation. Tracer gas studies are shown to be useful for the assessment of air mixing inside confined spaces.
