Sour Gas

The sour (H2S) content of hydrocarbon fields worldwide is increasing, and many natural gas fields have very high H2S – sometimes in excess of 50%. H2S is extremely dangerous because, although people can smell it at low levels (about 5 ppb) it does not smell much worse at the exposure limit value of 10 ppm or at potentially fatal levels in excess of 100 ppm. Therefore smell is an unreliable means of determining dangerous levels. Existing H2S point sensors are maintenance intensive, slow to respond and provide limited coverage. Most H2S sensors do not work reliably in hot or cold weather, or in humid marine environments.

Open path monitoring with Boreal’s analyzer detects H2S (and/or CH4) leaks from oil and natural gas operations quickly and unambiguously. Path lengths can be up to 750m. Boreal analyzers can be used for fixed monitoring applications or for temporary protection of workers during construction projects.

Using the multiple channel system is now possible to provide complete facility perimeter coverage at relatively low cost. Linear array early warning detection systems, covering several kilometers with no breaks in coverage, can be established between large producing fields and nearby population centres.

H2S safety monitoring with the analyzers can be applied equally well to refineries and sulfur plants. In fact, our analyzers have been monitoring fence line levels of H2S at one US refinery for 8 years – over 70,000 hours of continuous trouble-free.

Boreal’s TDL technology has several benefits for Sour Gas detection:

  • Provides continuous and instantaneous response times and data collection.
  • Very reliably delivers accurate readings.
  • No interference with other gases and No False Alarms: “It finds exactly what you’re looking for.
  • Ease of data collection and interpretation.
  • Minimal Maintenance: checks internal reference cell every minute, robust design, and requires no consumables to operate.
  • Low (overall or amortized) cost of ownership (because they can last +20 years) and low operation and maintenance costs.
  • Our technology is as close to set, collect, and forget as possible.

Sour Gas (H2S) Leak Detection Applications:

  • Drilling for oil and gas wells

    In certain formations, the probability of encountering  H2S gas while drilling wells in high. Due to wind and other the environmental conditions, it makes it difficult for traditional gas detection methodologies to detect H2S if the gas blown away from the area in which the sensor can detect. Our technology covers large and small area sources and effectively monitors the perimeter of the facility to ensure the drilling crew that there are no leaks. Boreal’s technology offers 1 second response times while other technologies take 30-90 seconds to detect a leak. When dealing with H2S a second can mean the difference between life and death.

  • Upstream, Midstream, and Downstream Natural Gas Facilities

    Whether you are looking for H2S detection inside process buildings, pipe rupture detection over cooling towers, or for perimeter monitoring around your facility- Boreal has you covered. With a number of different measurement heads and probes Boreal has the H2S detection solution for which you are looking for. Boreal’s technology offers 1 second response times while other technologies take 30-90 seconds to detect a leak. When dealing with H2S a second can mean the difference between life and death.

  • Pulp and Paper Industry

    The Kraft chemical pulping process produces the dangerous H2S gas. Traditional gas detection methodologies  In order to protect operational personnel it is prudent to deploy the technology that not only accurately and reliably detects the gas but does so with a 1 second response time. Other gas detection technologies have response times of 30-90 seconds. When dealing with H2S a second can mean the difference between life and death.

  • Swamps, Wetlands, or Landfills

    Naturally occurring H2S over open area sources is difficult to monitor and measure. Boreal has a number of open-path monitoring solutions that other technologies cannot do. Being able to accurately and reliably quantify the amount of H2S being produced in the swamps, wetlands, and landfills is now available with Boreal’s continuous monitoring analyzers.

  • Sewers, Sewage Treatment Facilities, and Manure Tanks

    H2S produced at refuse and effluent collection and treatment facilities pose a risk to operational personnel but to neighboring communities as well. Monitoring these processes are a challenge for traditional gas detection methodologies but with Boreal’s open-path measurement technology this is now a breeze.
