[Gasification] Gas Sensing Rig Update

[Hararat]

We have been using a thermal absorption technicque for the Hydrogen and IR for CO, CO2 and CH4.  We run at 1 lpm, no higher.  There is some drift but it can be monitored.  It's basically running on a vacuum pump pulling the gas from the discharge before the flare stack.  It must be filtered and cooled before hitting the sensors so we use a combination of fine filters in series with a dryer.
