Chapter 1. Features and Capabilities
1.5 Typical Applications
The XMTC can be used in a wide variety of industrial applications where it is necessary to measure the concentration
of one component of a binary gas mixture. It can also be used in pseudo-binary gas mixtures where the ratio of
concentrations of the background gas components remains constant, and in gaseous mixtures where the thermal
conductivity of the gas of interest is significantly different from that of the background gas. Some typical industries and
applications include:
• Metals Industry -
H
2
in heat treat furnace atmospheres
• Electric Power Industry -
H
2
in generator cooling systems
• Gas Production Industry -
Purity monitoring of argon, hydrogen, nitrogen, helium
• Chemical Industry -
H
2
in ammonia synthesis gas
H
2
in methanol synthesis gas
H
2
in chlorine plants
• Food Industry -
CO
2
in fermentation processes
Ethylene Oxide (ETO) sterilization
• Steel Industry -
H
2
in blast furnace top gas
• Petroleum Industry -
H
2
in hydrocarbon streams
Two very common applications are:
• H
2
in N
2
in heat treat furnace atmospheres: zero-based 0-25% H
2
, 2-Port (sealed reference gas, air)
• H
2
purity in H
2
electricity generator cooling: zero-suppressed, 80-100% H
2
, 4-Port (flowing reference gas,
100% H
2
)
For more details on these applications, refer to Appendix B, Applications. For details on applications not shown in
Appendix B, or if you wish to discuss your own application, please contact GE.
