Transportable Multi-gas Process Analyzer
The Transportable Analyzer System is designed to monitor a gas
process for gas composition, temperature and pressure.
The system includes electrically powered equipment to sample toxic,
flammable, possibly explosive gases and uses high-pressure gas
cylinders for calibration.
The system is housed within two NEMA 4 electrical enclosures that
are permanently mounted on a four-wheel cart.
The heart of the system is ARI’s Laser Gas Analyzer (LGA), which
is a self-contained gas sampler/analyzer that uses the principles of
Raman spectroscopy to simultaneously identify and quantify eight (8)
gaseous compounds. The system connects the analyzer to eight (8)
gas-sampling ports via a unique valve manifold. Sample scheduling,
which is user configurable, generally cycles continuously through
the eight ports, one after another. Sample time at each port is
typically 10 to 15 seconds.
The system includes ARI’s multi-port-purge system that uses
an auxiliary pump to simultaneously pre-purge one
or more sample lines while concurrently analyzing gas in a specified
line. This shortens the time between port-gas measurements by
keeping the sample lines filled with fresh sample gas. The system
also includes ARI’s nitrogen back flush system. Should any of the
eight sampling lines become restricted or plugged, pressurized
nitrogen can be forced backwards down the line to clean it.
The transportable unit includes on-board calibration gases for
daily calibration. The system also optionally includes temperature
and pressure monitoring. The sample site may be at the same location
as the gas measurement or at a different location.
