Process Gas Sampling System
The Process Gas Sampling System connects a gas analyzer to
multiple gas-sampling lines via a valve/manifold system. The valve
bank is modular to accommodate various gas sampling system needs.
Each module consists of four stainless steel valves. Sample
scheduling is set to continuously cycle through the sampling ports,
one after another.
The system includes a multi-port-purge system that uses an
auxiliary pump to simultaneously pre-purge one or more sample lines
while simultaneously analyzing gas in a specified line. This
shortens the time between port-gas measurements by keeping the
sample lines filled with fresh sample gas. Sample time at each port
is typically 10 to 15 seconds. A PC-based control system running MS
Windows 2000 is required to operate the sampling system. ARI
supplies the sampling system software and system setup to user
specifications.
The system also includes ARI’s nitrogen back flush system. Should
any of the sampling lines become restricted or plugged, pressurized
nitrogen can be forced backwards down the line to clean it. The
sampling system optionally includes highpressure calibration gas
cylinders mounted within an enclosure. Each calibration gas has its
own on/off valve and pressure regulator. A system may optionally
include continuous monitoring of gas pressure and temperature from
multiple locations.
