Analytical Systems Int’l. Keco Continuous Sulfur Analyzer Series 1600

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.
