The petrochemical, gas processing, biogas, landfill and gas pipeline industries have for many years needed an accurate, dependable, efficient, and cost-effective trend H2S and CO2 analyzer for quality and process control purposes. Now, KECO has met these requirements with a proven microprocessor based technology which provides continuous on-line analysis based on the electrochemical and NDIR principal of operation. The gas being analyzed for H2S and CO2 is regulated to 10 PSI, then a flowmeter regulates the flow to approximately 1.5 SCFH.
Next, the sample is introduced to the electrochemical detection element and NDIR sensor which provides an output proportional to the concentration of H2S and CO2. The signal is then digitized and analyzed by the advanced microprocessor and related software. The color touch-screen LCD display provides the current reading, previous reading, historical and real-time charts, 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.
