Description |
| The
petrochemical, gas processing, & gas pipeline industry has
for many years required an accurate, dependable, low
maintenance, and cost effective sulfur analyzer for quality
and process control purposes. With over twenty years of
experience in developing and manufacturing sulfur analyzers
and associated parts and supplies, Analytical Systems
International has met these requirements with a unique &
proven microprocessor based analyzer, which provides
continuous on-line analysis based on the only absolutely
specific lead acetate principal of operation. The Model 1600
system measures total sulfur by hydrogenation, similar to
that as described in ASTM Method D3031, D4084-82, D4468-85,
& 4045-81. The sulfur sample is precisely metered into a
continuous flowing stream of hydrogen gas. The sample and
hydrogen are heated in the furnace up to 1,315 degrees C
resulting in thermal cracking of the sulfur which are
reduced to short chain hydrocarbons. These reactions result
in the formation of H2S. After complete humidification of
the sample the H2S comes in direct contact with the lead
acetate tape which produces a darkening of lead sulfide
immediately measured by the photodiode/LED optics &
rate-of-reaction digital electronics to provide an accurate
and reproducible total sulfur analysis with PPB or PPM
sensitivity up to 100%. The LCD display provides the current
reading, any alarm condition, procedure prompts (such as
calibration procedure), and failure indicators (local and
remote capability). Quality materials are selected for their
compatibility and are utilized throughout fabrication.
Special attention is given to wetted parts that come in
contact with the process stream and are selected to be non
reactive with H2S. |
