H2S Monitoring and Detection

Recent advances in laser technologies for Hydrogen Sulfide (H2S) detection are creating opportunities for effective area monitoring for health and safety applications. TAS has been at the leader in this technology and application development and has fielded several H2S fenceline monitoring systems for real-time H2S monitoring and reporting with detection limits that meet the needs for small area safety detection.

H2S Hazards

H2S is a significant industrial health and safety concern. Although significant resources are applied to personal and area detection of H2S gas, all these monitors contribute to significant operations costs. Not only do they require routine calibration and maintenance, but they suffer from slow response, false positives that result in significant operational losses, and false negatives that can result in life and health hazards. TAS provides advanced technology systems to reliably monitor hydrogen sulfide in industrial settings.

TAS Expertise in Industrial H2S Detection

TAS has designed open path detector systems for reliable H2S area monitoring using technologies from manufacturers such as Boreal, Unisearch Associates, and Cerex Monitoring solutions. These applications include small refinery operations areas, sour gas plant perimeters, refinery waste treatment, sour gas coolers, and fenceline monitoring. Open path H2S applications have been limited by sensitivity; the open path technologies simply lacked the sensitivity to be effective. TAS has is changing that.

Industries Using H2S Detection

  • Petroleum production and refining
  • Sewer and wastewater treatment
  • Agricultural silos and pits
  • Textile manufacturing
  • Pulp and paper processing
  • Food processing
  • Hot asphalt paving
  • Mining

Acute Hazard H2S Detection Applications

Certain operations in the petroleum production and refining industries and some mining operations can present an immediate H2S hazard. Often these are addressed by personal monitors and in some locations by area monitors for health and safety applications.

Low Concentration H2S Detection Applications

Waste management and pulp and paper applications for H2S monitoring have been challenged by sensitivity and specificity problems. The advances made by TAS in H2S monitoring promise new applications for treatment ponds, waste management, agriculture waste, and mining.

Very Low Concentration H2S Detection Applications

Recent developments make laser based H2S detection methods useful for some very low detection applications. H2S monitoring from natural sources and waste treatment areas has been demonstrated well below 30 ppb, presenting opportunities for detection near the odor threshold. This presents opportunities in applications including landfills, treatment ponds, industrial fencelines, sewer gas, agriculture, and natural sources.
