Are your gas analyzers routinely contaminated by liquids? Is there something you can do about it? Now there is a high-tech patented solution that will save you money and headaches.
Introducing PhaseAlarm(™)
Phase Alarm is a revolutionary new device that will detect the presence of liquids in your gas sample before it enters your other gas analyzers such as GCs, moisture, H2S, CO2, or oxygen sensors.
Simply install PhaseAlarm upstream of your other analyzers. PhaseAlarm(™) will detect the presence of any and all liquids in your gas stream. If liquids are detected, it will trigger an alarm that can be used to divert the gas flow away from other analyzers. Or use the optional integrated 3-way valve to do the same thing.
PhaseAlarm(™) will save you from the hassles of GC column replacement, TDLAS mirror cleaning, moisture sensor fouling and other problems associated with liquid contamination.
How Does it Work?
PhaseAlarm(™) works based on ZEGAZ Instruments patented phase detection technology. This technology has been developed and perfected over the past few years at ZEGAZ Instruments and has been tested at leading customers with stellar performance.
What are some of the problems that PhaseAlert(™) can detect and address?
1- Gas Probe Sampling Liquid from the Pipe: There are pipes that sometimes have liquids in them. A gas probe may sample that liquid and now you have liquids in your gas lines that go to your gas analyzers. Installing PhaseAram(™) right after the probe can detect the intrusion of liquids. An alarm will allow you to be notified of the problem to address it.
2- Heat-traced Tubing Failure: Most gas lines going to analyzers are heat-traced to make sure that the gas remains in 100% vapor phase. If the heat-trace fails for any reason, for example loss of power, liquids may form in the gas line. PhaseAlarm(™) installed before the analyzers can detect the presence of liquids. It can also report the gas temperature that provides additional insight for the user to take action.
3- Creation of Liquids due to the JT Effect: Many gas analyzers (including GCs, TDLAS, etc) work at near-atmospheric pressures. The pressure has to be reduced before introducing gas into these analyzers. Such pressure reduction on its own, or in combination with the JT effect, may lead to creation of liquids. Installing PhaseAlarm(™) before the analyzers will detect the liquids and can divert the flow away from the analyzers.
What About Membrane Filters
Traditionally membrane filters have been used to remove trace amounts of liquids from gas samples. However, the filters are not full-proof and occasionally fail. Furthermore, they can only remove small amounts of liquids. Even if you are using membrane filters, it is prudent to have an independent check on their viability. PhaseAram(™) will allow you to detect the presence of liquids after such filtration to make sure there are no liquids.
