A Flir GF320 gas camera is enabling Norwegian waste treatment company Lindum Ressurs og Gjenvinning to spot methane leaks, prevent uncontrolled gas venting and keep the air clean at and around its landfill sites.

Lindum’s main site in Drammen, Norway, features a biogas production plant and a large landfill consisting of selected solid waste covered with clay layers. The methane gas produced by the landfill is extracted and used for power production and residential heating.

The landfill also discharges hydrogen sulphide, a gas that can be an irritation for surrounding residential areas.

To detect these gas leaks, Lindum purchased the Flir GF320 infrared camera, which traces and visualises about 20 volatile organic compound (VOC) gases including methane.

Key benefits of product application

  • The landfill is inspected twice a week at dawn for about one hour; the GF320 instantly shows gas leaks, visualised as black or white plumes.Landfill workers can then cover the leaks with clay and an ironed mass to neutralise the sulphide odours.
  • The GF320 gas imaging camera also enables the inspection of the biogas production piping on a weekly basis.
  • Using the camera as both a maintenance and safety tool, Lindum has made estimated savings of more than $12,000 (£9,500) per year and has been able to reduce the foul odour nuisance considerably.

FLIR Systems specialises in technologies that enhance perception and awareness.  The company brings innovative sensing solutions into daily life through its thermal imaging and visible light imaging technology and systems for measurement, diagnosis, location and advanced threat detection.  Its products improve the way people interact with the world around them, enhance productivity, increase energy efficiency and make the workplace safer.

FLIR Systems has six operating segments – surveillance, instruments, OEM and emerging markets, maritime, security and finally, detection. Of these six, ‘instruments’ is of greatest interest to trade and industry and the second largest segment in the company’s portfolio. This division provides devices that image, measure and assess thermal energy, gases and other environmental elements for industrial, commercial and scientific applications.

These products are manufactured across five production sites, three in the USA and two in Europe; Sweden and Estonia.

A model to suit every application and budget
The options that FLIR Systems provides for measuring temperature and studying thermal performance have never been greater.  Not only does the company offer a huge range of models to suit all thermal application needs but the technology is also affordable and very easy to use.  Thermal cameras now come in various shapes, sizes and degrees of sophistication and FLIR continues to invest heavily in the development of new and complementary technologies to differentiate itself from competitors.

An important milestone in the development of thermal imaging has been the introduction of the FLIR Lepton® core, a micro longwave detector, the size of a mobile SIM.  This has allowed thermal imaging to be repackaged to meet the needs of an even wider audience and, in combination with another new technology called Infrared Guided Measurement – IGM™ – has led to the development of a range of test and measurement meters with imaging capability.

Another important growth area for FLIR thermal imaging is in continuous monitoring to assure quality and safety.  Through its introduction of discrete fixed mounted thermal cameras which are fully compliant industry standard plug-and-play protocols, FLIR Systems has provided industry with infrared machine vision which is instantly ready for quick and easy network installation.

Protecting assets and people from fire is an area for which thermal imaging is least known but, thanks to FLIR Systems’ development, it is now one of the most cost-effective methods available.  Its application flexibility and rapid return on investment present an attractive proposition for any site or safety manager.
