This article covers the different methods and scientific techniques behind optical gas imaging including how the detectors operate, cooling methods, and image normalization. Additional topics include spectral adaptation, gas infrared absorption spectra, gas stream visualization, and key concepts for making gas clouds visible.
Inspectahire is a company that helps customers manage the safety, profitability, and environmental impacts of their assets through remote visual inspection technologies and solutions. The FLIR’s GFx320 Optical Gas Imaging (OGI) camera is their preferred technology to use when tasked with the detection of fugitive hydrocarbon emissions.
A power plant must keep up maintenance of the hydrogen-cooled generators for the safety of its workers and the environment, as well as for efficient operation of the plant. Traditional methods for hydrogen leak detection in a cooling system may be able to find the general area where hydrogen is present, but can be unreliable at finding the source of the leak. The introduction of optical gas imaging cameras has greatly improved the efficiency and performance of leak detection. With the addition of a dedicated thermal imaging camera for CO2 leak detection, utilities now have a way to efficiently find hydrogen leaks while using CO2 as a tracer gas.
The oil and gas industry loses an average of eight million metric tons of methane through gas leaks every year. Although this does not equate to some major methane leaks in the past, such as at the Aliso Canyon natural gas storage facility in 2015, the industry is still faced with how to best find and repair leaks at potential escape points. As an alternative to the industry standard for leak detection and repair, Optical Gas Imaging (OGI) is being used to make surveys easier and more efficient.
The Al Hosn Shah Gas Processing Plant in Abu Dhabi is a natural gas processing plant that purifies gases by removing certain contaminants in a sweetening process. The gas pipelines and other infrastructures that process sour gases need to be continuously monitored for leaks as the contaminant gases are often dangerous for human exposure. This case study explores the innovative combination of UAV and FLIR optical gas imaging technologies as an efficient way of monitoring vast gas fields from the air.
BP Chemicals produces acetic acid and is responsible for a significant portion of the world’s capacity. Every year, the company invests millions of pounds into improving production efficiency, minimizing environmental impact, and protecting its employees.
The process of detecting gas leaks within industrial facilities can be susceptible to human error and interpretation, as well as dangerous and time-consuming. The RoboGasInstector is a type of robot system that was created with the intention of providing a safer, more efficient, and more reliable gas detection solution. This system delivers remote detection and localization of gas leaks, and was developed by a group of German companies and institutes. It uses a FLIR GF302 optical gas imaging camera.
As awareness of leaks within biogas facilities has grown, gas camera technology has also increased in use in order to easily show leaks. This application note explains how the FLIR GF320 was used to assess leakage in biogas facilities.
