AADCO Instruments offers free standing methane reactors (Models 153 and
154, Figure 10) for those individuals who wish to remove hydrocarbons and
carbon monoxide from their own oxygen or air sources. It should be borne in
mind that suitable halogen and sulfur scrubbers are required if these
compounds are present, when using these free-standing units. The Models
153 and 154 are also ideal for destroying the ethylene used as excitation gas
for chemiluminescent ozone analyzers rather than venting the ethylene within
the monitoring vehicle.
10.8
The temperature of the methane reactor is monitored by the panel mounted
pyrometer, Figure 4 (7). Confirmation that the unit is operating at a controlled
temperature is made by observing the METHANE HEAT lamp Figure 4 (4)
which will cycle when at operating temperature. Should the pyrometer indicate
a temperature other than 290
C ± 10
C, refer to Section 13.22 for remedial
action.
