phosphine concentration

Categorised under:

Catalogue: GRDC Final Reports
In one trial, for example, head-space temperatures measured during the day were as high as 61 C. Gases expand as they are heated so the possible effects of diurnal heating and cooling of the head-space on phosphine leakage from the silo and phosphine distribution within the grain mass need investigation... Silos containing grain were pressure tested to give an indication of gas-tightness measured as the pressure halving time (P1/2)... In the project, phosphine concentrations were measured during storage mainly along the vertical mid-axis of the silo, but sometimes at other locations...

Paul Kamel (left) and Les Zeller on-site at Tammin, WA, with the telemetry equipment installed to relay data on phosphine concentrations directly to a central database... The step would have removed the need for data from the phosphine monitors to be gathered and recorded manually... The automated phosphine monitoring system is designed to gather information including temperature, humidity and the concentration of phosphine being recirculated and also references this data with the silo being recirculated...
