Description |
The
petrochemical, gas processing, and gas pipeline industry has
required an accurate, dependable, low maintenance, and
cost-effective sulfur analyzer for quality and process
control purposes. With over twenty-five years of experience
in developing and manufacturing sulfur analyzers and
associated parts and supplies, Analytical Systems
International (ASI) has met these requirements with their
proven microprocessor based analyzer. The Model 1700 System
measures total sulfur by hydrogenation similar to that as
described in ASTM Method D3031, D4084-82, D4468-85 and
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° C resulting in thermal
cracking of the sulfur that 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 and
produces a darkening of lead sulfide that is immediately
measured by the photodiode/LED optics and 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 (i.e., calibration
procedure), and failure indicators (local and remote
capability). Quality materials are selected for their
compatibility and utilized through 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. |
