Description |
The
petrochemical, gas processing, and gas pipeline industry has
required an accurate and dependable, low maintenance and
cost-effective H2S analyzer for quality and process control
purposes. With over thirty years of experience in developing
and manufacturing gas analyzers and associated parts and
supplies, Analytical Systems International has met
these requirements with their proven microprocessor based
analyzer. This hydrogen sulfide analyzer or monitor provides continuous on-line
process analysis based on the specific and interference free
ASTM approved tape principle of operation. The process stream is
regulated to 10 PSI. Then a precision flow meter regulates
the sample flow and is humidified. Next, the sample is introduced to the
specific lead acetate sensing tape that provides an output
proportional to the concentration of H2S through the
photodiode detector and LED light source optical system.
This signal is digitized and analyzed by the advanced
microprocessor and related software resulting in a linear
4-20ma output. The LCD display provides the current reading,
any alarm condition, procedure prompts (i.e. calibration), and failure indicators. Quality materials are
selected for compatibility and are utilized throughout the
manufacturing process.
This reliable field proven analyzer system continuously and
specifically quantifies the H2S level in the sample with
minimal maintenance. The principle of operation is described
in various ASTM methods include D4084-82, D4468-85, and
D4045-81. |
