GAS DETECTION Monitoring flue gas emissions


helps determine the process efficiency and protect the environment, and demonstrates that plant operators are complying with the necessary regulations. To ensure compliance, a


continuous emissions monitoring system (CEMS) is required to measure all the necessary components of the flue gas. This must be capable of offering the highest sensitivity and accuracy when dealing with multiple measurements for pollutants. Any gas analysis system must


also meet MCERTS and QAL1 certifications to comply with regulatory criteria.


Cleaner energy sourCes


Cleaner energy sources, such as hydrogen, are becoming increasingly attractive to many


industries – hydrogen gas (H2) does not contain carbon, so


cannot form CO2 as a byproduct of combustion. Plants that produce hydrogen


are ramping up output to meet increased demand. The purity of the hydrogen they produce affects its quality as a fuel, and this is where gas analysis again plays a major role. Depending on the


manufacturing method, the most common contaminants will be O2, CO and CO2. All three of


these can be monitored by gas analysers to ensure product purity.


a Cleaner future


Whether it is used to ensure more efficient processes, to support the safe removal of pollutants, or to monitor the remaining emissions that are output to the atmosphere, gas analysis plays an essential role in cleaner plant and refinery operations. Additionally, it is certain that


gas analysis technology will be essential to the production of current and future cleaner energy sources. A wide range of sensing


technologies is needed to achieve all the necessary goals of a clean air strategy in order to ensure the best-fit and most cost-effective solution for each application. By combining all three stages


of the clean air strategy outlined here, plants and refineries can fully address the impact of their operations on the wider environment, and contribute fully to the creation of a world with cleaner air. Find out more about the

ensirion has developed a stationary methane leak detection system - Nubo Sphere. It is designed as a future-proof, end- to-end solution offering high performance at low total cost of ownership, thus changing the state-of-the-art in methane leak detection. It has never been easier to reliably locate and quantify unintended methane emissions across various


industries. The deployment of real-time, continuous methane concentration data enables leak detection much earlier than was previously possible through human interaction, ensuring fast, accurate and cost-saving damage control through rapid incident response actions for increased safety and a reduced environmental burden. Methane (CH4) concentrations in the atmosphere have increased by


more than 150 per cent since 1750 and are considered a major


contributor to global warming. CH4 has been identified as an even more powerful greenhouse gas than CO2, making an immediate reduction of emissions necessary. Given its short-lived nature, there are actionable options that reduce the environmental burden on a


short timescale. In the US alone, around 13 million tons of CH4 are being released into the air each year - enough to heat ten million homes for a year. Studies show, however, that only about 40 per cent


of CH4 in the atmosphere originates from natural sources such as volcanoes or permafrost soils, while the remaining percentage is


caused by human activities. Reducing that portion of the total CH4 emissions has thus become a priority for leading nations across the globe, as only then will it be possible to achieve the goals of climate initiatives like the Paris Agreement. And although anthropogenic emissions come from a variety of sources, the oil and gas industry represents the energy sector's largest source of emissions, holding the key to responding to the world's climate challenge. Sensirion has therefore developed a stationary methane leak


detection system, Nubo Sphere, for use along the whole oil and gas value chain. It is an end-to-end solution for real-time monitoring of methane emissions, offering high performance at low total cost of ownership. The compact and robust system design enables reliable and highly accurate data from any natural gas infrastructure at all times via data upload to the Nubo cloud. It is fast to deploy and easy to use, while two exchangeable sensor cartridges ensure low maintenance expenses and provide a future-proof, sustainable set-up. The system follows the concept of plug and play: mount your Nubo Sphere nodes on-site and start measuring within minutes. "With Nubo Sphere, we enable various industries, including oil and


gas, to locate and quantify methane leaks reliably and cost-efficiently. Sensirion's offering is unique: cost-efficient yet highly reliable, easy to use and maintain, and based on yet another innovative sensor technology from Sensirion. It makes me very proud to provide the oil and gas industry with the right tool to enable its efforts in methane emissions reduction and thus contribute to stopping climate warming", says Susanne Pianezzi, sales director at Sensirion.
