Determination
of Carbon Monoxide Emissions from Stationary Sources – USEPA
Method 10B
USEPA Method 10B is used for the determination of carbon monoxide
(CO) emissions at petroleum refineries and from other sources when
specified in an applicable subpart of the regulations.
An integrated gas sample is extracted from the sampling point, passed
through a conditioning system to remove interferences, such as carbon
dioxide (CO2)
and organics, and collected in a Tedlar bag. Most of the CO2
is removed from the sample by the alkaline permanganate conditioning
system; any residual CO2
and organics are separated from the CO by GC and catalytically reduced
to methane (CH4), which is determined by flame ionization detection
(FID). The analytical portion of this method is identical to
applicable sections in USEPA Method 25 detailing CO measurement. |
