FTIR resolution requirements for industrial gas analyzers

FTIR Spectroscopy is a widely used technique for gas analyses in industrial applications. It is a technique used in the semiconductor industry for measuring the purity of cleaning, etching, and epi-treatment gases used with various process tools, reactors, and abatement devices. Among chemical companies and R&D facilities, FTIR is applied to combustion thermodynamics and stack gas emissions; ...

Selecting and Placing Gas Detectors for Maximum Application Protection

Many industrial processes involve dangerous gases and vapors: flammable, toxic, or both. With the different sensing technologies available, and the wide range of industrial applications that exist, selecting the best sensor and locating them properly for the job at hand can be a challenge. To ensure a high level of safety, know the latest sensing technologies, which technology is best for the ...

Upgrading from Pellistor Gas Sensors to Infrared Technology

In this article Andy Avenell, Crowcon’s Fixed Systems Product Manager, considers the shift towards infrared (IR) gas sensor technology in the oil and gas industry. Abstract Flammable gases and vapours can present considerable dangers in many industrial applications, none more so than the processes involved in extracting, transporting and processing oil and gas. Fast and reliable ...

Detecting Gases: What You Can`t Smell Can Hurt You

Walking through a drill-site area, a worker smells rotten eggs and stops tor a minute or two to assess where a gas leak might exist. Rubbing his itchv eves as he investigates further, he notices that he no longer smells the tell¬tale hydrogen sulphide odour. He does not realize that the gas has deadened his olfactory senses and unless he leaves the area within seconds, he could lose ...

Taking Fossil Fuels to the Next Level - Standards Underpin Extraction, Processing and Distribution

To the average person, the oil and gas industry may appear simple — a matter of literally tapping into a natural resource and distributing it to customers. Of course the matter of extraction is rarely simple, and in the case of emergent hydraulic fracturing technology, it is particularly complex and capital-intensive. In fact, the world of petroleum and natural gas extraction, distribution ...

Composting releases less air pollution than previously thought - study

A new study funded by the California Integrated Waste Board (CIWMB) indicates that well-managed composting of green waste and food waste releases significantly less air pollution than previously thought. The study also demonstrates that a relatively inexpensive management technique - covering active compost piles with a layer of finished compost - may lower air emissions even further, by as ...

Three models of social change

Can we change fast enough? When thinking about the enormous need for social change as we attempt to move the world economy onto a sustainable path, I find it useful to look at various models of change. Three stand out. One is the catastrophic event model, which I call the Pearl Harbor model, where a dramatic event fundamentally changes how we think and behave. The second model is one where a ...

The New Environmental Insurance Products: When Does it Make Sense to Buy Them?

Part One Introduction Real estate transactions with environmental problems often founder on attempts to shift the liabilities from one party to the other. In transactions with other types of problems, insurance is a popular risk transfer mechanism, and is regularly used for that purpose, but it is used far less often when there are environmental risks. This so-called ...

Beliefs, Politics, and Environmental Policy

Introduction Many of us who work on environmental issues have faced the challenge of conveying their importance to nonspecialists. Perhaps we have found ourselves defending the robustness of climate science to a contrarian uncle, or extolling the importance of biodiversity to a dubious aunt. Our relations and friends are often educated people, skilled in their own professions, who have ...
