The Model 4400 In-Stream Hydrogen Sulfide Analyzer
isusedtocontinuouslyverifytheH2Scontentofanatu-
ral gas sample for the presence of 0-100 ppm levels of
Hydrogen Sulfide. This system is used to insure that
H2S levels in natural gas collection lines remains at ac-
ceptable levels to help guard against the corrosive ef-
fects of H2S on compressors, pipelines and process
equipment. Itisintendedforcontinuous monitoringprior
to the addition of odorants to the gas.
TheSierraMonitor Model 4400 provides the userwitha
low-cost,easy-to-usesolutionto effective monitoring of
naturalgasstreams. This system accurately measures
H2S concentration in the 0-100 ppm range. Fast re-
sponse of 90% of step change within 30 seconds en-
ables the user to respond quickly to changes in natural
gassupply conditionstopreventproduct contamination.
Thereisminimal maintenance withtheModel4400with
no tapes to replace, no conditioning solutions, no me-
chanicalstreamblenderstocalibrate. Calibrationiseasy
with external application of span gas and simple one
person adjustments. Calibration and swapping of the
gas sensor is a quick and simple operation performed
everytwoweeks.
The 4400-10 receives a low pressure natural gas slip-
streamsample. Aflowcontrollerinthesystemdelivers
a constant flow to the gas sensor and allows for easy
calibrationand maintenance. An in-linecoalescingfilter
protects the system from sample contaminants.
