Gas detection

Gas detection: Oil & Gas industry

Gas detection is a key point in the safety of workers and environments and ensures accuracy even in the harshest environments such as the Oil & Gas industry, providing early warning if limits are exceeded, allowing rapid intervention and preventing possible gas leaks, explosions or fires. The oil & gas industry consists of hostile environments where workers are exposed to significant risks, and the adoption of fixed and portable gas detection systems is a reliable and safe choice.

Gas detection: How the oil & Gas industry is divided

The oil industry is divided into 3 major macro-categories:

  • Upstream
  • Midstream
  • Downstream


Rilevazione gas Upstream

Dedicated to the detection and extraction of oil and natural gas, it includes both onshore and offshore drilling operations. This phase requires the use of specific machinery and equipment, which require careful use and proper preparation by workers. It is here that the first hazard from gases is encountered: hydrogen sulfide.H2S is extremely toxic and flammable, and can cause loss of consciousness and even death even at low concentrations. Therefore, accurate and reliable gas detection is essential.



Rilevazione gas nel MidstreamIt concerns the storage, transportation, and processing of crude oil and natural gas. During this phase, which takes place through pipelines overland or large tankers by sea, gas detection is critical to ensure the safety of workers and prevent possible leaks or spills, helping to ensure the integrity of storage tanks and transportation equipment.



Rilevazione gas nel downstreamIt includes the refining and processing of oil and natural gas to the distribution of finished products. It is at this stage that raw materials are processed and transformed until they become usable in a wide variety of areas, from fueling to heating homes. At this stage, natural gas is divided into hydrocarbons and fluids in order to produce pipeline-quality gas.

Gas detection: major hazards in the oil & Gas industry

Among the most common gases in the oil industry is methane, a flammable gas that can pose a safety hazard to workers and environments. One possible solution to detect it is the use of infrared technology sensors, known for their accuracy long-term stability. Another very common gas is hydrogen sulfide, which is extremely toxic and flammable and can cause unconsciousness and even death.It is possible to detect it through the use of electrochemical cells, which can detect even very low concentrations of the gas.
