Hydrogen sulfide measurements for quality and process control

Analytical Systems Keco August 1, 2023

Petrochemical gas processing facilities, chemical plants and the biogas industry can rely on the SulfurHound H2S in Gas Analyzer to provide accurate, dependable and cost-effective measurement of hydrogen sulfide in natural gas pipelines, gas wells and landfills for quality and process control.

Accurate measurement of hydrogen sulfide (H2S) in natural gas, biogas, and air is critical in meeting air quality standards, avoiding pipeline corrosion, eliminating odor and ensuring public health and safety. For example, refineries measure hydrogen sulfide to protect process equipment and ensure product quality, while gas processors monitor for hydrocarbon leaks in cooling towers, heat exchanges, and condensate boilers. Biogas, produced from the waste products of treatment plants and landfills, creates H2S that must be controlled to avoid harmful odors that emit into the atmosphere.

Many traditional H2S analyzers provide slow responses, resulting in undetected failures and unnecessary downtime. The SulfurHound H2S in Gas Analyzer resolves this by providing continuous online analysis based on the electrochemical principle of operation. When analyzing gas, the SulfurHound uses anelectrochemical detection cell to provide an output proportional to H2S concentration. An output signal is digitized and analyzed by an advanced microprocessor and related software. KECO’s H2S analyzer accurately and quickly measures H2S in real time, giving facility operators critical information.
