How Does a Gas Analyser Work?
Whatever you want to detect, you need to identify a property of the object that is easy-enough to measure. When it comes to monitoring and analysis of gaseous species (atoms or more commonly molecules), it turns out that it often is possible to utilize the optical properties of the gas. You need a light source, a light detector, and a characteristic behaviour of the gaseous species in question ...

Accuracy In Adversity
It is a fact of the industry that oil and gas companies are required, by various rules and regulations, to routinely perform gas sampling to establish gas composition, flow rates and gas properties. In order to comply with regulations, gas sampling tools must achieve high accuracy at low flows with varying gas compositions, temperatures and pressures. For many technologies, these requirements can ...

Molecular Beam Gas Analysis with Hiden Analytical
Molecular beam mass spectrometry (MBMS) is used for quantitative gas analysis of reactive species and intermediates formed in various processes. Gas phase intermediates are sampled from reaction chambers using a differentially-pumped inlet, which forms a molecular beam of radicals, ions, polymers, or clusters. This is directed through a vacuum chamber and onto an ion detector. Due to the ...

New, low gas absorption, electronic water condenser for use in gas analyzer sample conditioning systems featuring the “m class” electronic water condenser
INTRODUCTION Electronic water condensers are an effective means of removing water in combustion waste gas streams and process samples, prior to analyzing with a gas analyzer. In recent years, electronic water condenser have found prevalent use in Continuous Emissions Monitoring Systems (CEMS). As air quality regulations have required lower emission levels for criteria pollutants (N0x, S0x, C0, ...

Thermal Activation of Digested Sewage Sludges for Carbon Dioxide Removal from Biogas
Sewage sludges from a wastewater treatment plant (WWT) were anaerobically digested for the biogas production and energy use. The refuses of such process were used as starting material for the char production for the gas cleaning process. These char samples were experimentally tested as adsorbents for the removal of CO2 and trace contaminants from the biogas mixture produced from the WWT plant. A ...

In-situ continuous emissions monitoring & regulatory compliance
As environmental scrutiny has risen and regulation has tightened in recent years, the importance of having accurate information on the environmental performance of your power plant has increased. After all, if you want to manage something, you need to be able to measure it. The analogy is obvious; you wouldn't start a diet without first investing in a set of scales. So it is with Continuous ...

Unmanned remote and wireless CDM monitoring case study
Remote and wireless monitoring technology to meet CDM requirements is in its infancy in Europe. Carbon trading is driving it globally, especially in North and South America. That experience and technology is now finding a demand in Europe and Asia in landfill, biogas from food and animal waste in digesters and water treatment sludge digestion. Methane recovery from landfill and anaerobic ...
