INESC Porto’s Optoelectronics and Electronic System Unit (Porto, Portugal) in partnership with the European Space Agency, has developed a technology that enables a more effective measurement of gases in the atmosphere than that achieved with current techniques (such as atmospheric balloons and specially equipped airplanes). The system consists of an ultra-narrow spectral tunable and heat-reflecting filter based on optical fiber technology that can be used to monitor the atmosphere with the reflection of laser impulses. If it is applied to satellites, this filter will be able to detect pollutant gases in the Earth’s atmosphere in concentrations less than 1 km high and 50 km wide, at an altitude of 400 km. This technology is capable of providing precise measurements of several greenhouse gases including carbon dioxide, methane, nitrous oxide, and ozone.

Sensi+, fast, accurate and reliable monitoring of H₂S, H₂O and CO₂ in natural gas
October 31st 2024Sensi+ is a compact natural gas contaminants analyzer based on a unique tunable diode laser (TDL) technology called Off-Axis Integrated Cavity Output Spectroscopy (OA-ICOS™). The technology accurately, reliably, and simultaneously measures corrosive substances such as hydrogen sulfide, carbon dioxide and water in real-time within complex and time-varying natural gas streams. Mitigating the risks and effects of contaminants in natural gas can be challenging for pipeline operators, process industries, and natural gas utilities. These companies must manage various technologies and devices to achieve a comprehensive analysis, which can be complex, prone to failure, and costly. ABB's revolutionary Sensi+™ analyzer answers these issues.
