Model 682T-HP
On-Line Sulfur Analyzer

The Model 682T-HP is designed for analysis
of sulfur in highly viscous hydrocarbons. This
system is ideal for processes where sample
pressures are high and in situations where
fouling of flowcell windows with paraffin
or similar substances can occur. On-line
monitoring of sulfur in crude oil, marine bunker
fuel, and blending operations, are a few
examples of where the 682T-HP is currently
being used.

ASOMA Instruments was established in Austin, Texas,
in 1979 as one of the first companies to offer lowcost benchtop EDXRF instrumentation. Through the
years, ASOMA has become an industry leader with the
development and release of the Phoenix II series of XRF
analyzers, as well as a complete line of instrumentation for
measuring liquids, solids and coatings.

tt The Model 682T-HP system is faster,
more sensitive and more compact than
previous systems and provides continuous,
reliable detection of sulfur at working process
pressures. It can operate either as a standalone analyzer or can be tied in to plant-wide
automation systems to provide real-time
strategic measurements.

tt Among the key features of the analyzer
are a fully integrated densitometer, automatic
density compensation, touch-screen controls,
password protected screens, and rapid
update rates as frequent as one per every five
seconds.

tt Operation of the analyzer is regulated
by an integral processor. The processor
monitors instrument parameters such as
process temperature, density, and system
diagnostics. It also provides a comprehensive
suite of alarms and a standard platform for
communicating to a plant-wide DCS. Due
to its unique design and robust construction,
the system has minimal, if any, sample
conditioning and recovery requirements.
