Detecting Flammable Hydrocarbons for Fuel or Propellants

Propane also has agricultural and manufacturing applications, while butane is used as a fuel additive, an accelerant, a refrigerant, and a component of other chemicals. Leaks of either chemical can cause explosions. The ability to detect fugitive emissions from faulty valves, storage, and transport systems – and to do so from a safe distance – is therefore critical.

OGI Application Stories

Environmental protection with a FLIR optical gas imaging camera

Some industrial, pharmaceutical and petrochemical plants emit gases that can harm the environment and impede the health of company employees and inhabitants of the surrounding area. Environmental protection agencies have the responsibility to make sure that these emissions fall within governmental and international policy guidelines. To help them with that task environmental protection agencies can use an optical gas imaging camera.

FLIR optical gas imaging camera helps improve environment and safety at Borealis Stenungsund

Many petrochemical plants handle invisible gaseous hydrocarbons. Most of these gases pose some sort of safety aspects. They may be toxic, or can cause health issues in case of long term exposure. Others are highly flammable, explosive even, and most of them will have a negative impact on the environment if they enter the atmosphere in large quantities. That is why leak detection is of vital importance in these petrochemical plants.

Ten tips to get the most out of your OGI Camera

Optical Gas Imaging (OGI) cameras use spectral wavelength filtering and Sterling cooler cold filtering technology to visualize the infrared absorption of VOC/hydrocarbon, SF6, refrigerants, carbon monoxide and other gases whose spectral absorption matches the response of the camera.
