TECHNOLOGY OVERVIEW

Gas leakage detection system is an importance part of a safety system, providing early warning against possible disasters of gas leakage. Gas is increasinly used in both industrial and residential environment, and hazardous gas leakage if goes it go undetected, can be disastous. However, there are not many detectors avaiable in the market to detect hazardous gas leakage due to chemcials or fuels. This technology provides an imaging solution for gas leakage detection of hazarous gas like methane.

The technology consists of 2 types of low pixel count infrared (IR) cameras with both advanced sensing techniques and a proprietary algorithm. This allows for:

  • Passive camera: imaging with external IR light sources (sun, heat sources, lamp or other artificial IR light sources etc.).
  • Passive/Active camera: In addition to passive camera, the active mode relies on active IR laser patterns.

Similar to wide-field IR cameras, the technology could monitor a larger site and hence, the site monitoring could require fewer detectors and hence, the cost of using conventional cameras as detectors.  The technology allows for hybrid serial and parallel detection with propriety algorithm that uses enhanced frame rate to achieve real-time industrial standard images.

TECHNOLOGY FEATURES & SPECIFICATIONS

The technology provides an imaging solution without an expensive detector array. With a hybrid detection system and proprietary algorithm based on compressed sensing, the technology could offer gas leakage detection in real time.

The technology could be integrated into handheld devices to find the gas leakage positions. It can also be integrated into CCTV system to provide fixed location security and gas leakage surveillance. With this revolutionary gas detection technology, it could potentially replace existing solutions and introduce a new safety practice for industry.

The features offered in this technology include:

  • Large surveillance coverage
  • Few detectors usage
  • Detection independent on wind direction
  • Possible to locate source of leak
  • High speed detection and localization
  • Robustness in bad environment condition
  • Minimum sensitivity to optical alignment
  • Affordable cost

POTENTIAL APPLICATIONS

The global gas detectors market is valued at US$ 2.6 Billion in 2018 and is projected to reach US$ 3.6 Billion by 2025, at a CAGR of 4.8% during the forecast period, because of increased safety awareness and requirements all over the world. The Best Available and Safest. Technologies (BAST) Determination Process recent studies reviewed and confirmed that the Optical Gas Imaging (OGI) technology is the most effective to detect methane gas leak detection, to enable the operator to see the vapor gas cloud in real time. However, the prohibitively high cost has made it difficult for full implementation in site operations, an issue that the current technology could address.

This technology adequately addressed the above and covers a wide range of hazardous gas leak monitoring applications such as:

  • Oil and Gas Climate Initiative (OCGI) devices in oil and gas operations
  • Detect methane gas leak, to enable the operator to actually see the vapor gas cloud in real time   
  • Applicable Industries include - Upstream oil and gas productions such as drill wells, extraction of chemical supply; midstream sector such as pipelines and tank farms; downstream sector such as refining of petroleum crude oil, processing and purifying of raw natural gas.
