Gas Tungsten Arc Welding - an overview | ScienceDirect Topics

When using pure argon to shield GTAW joints, the result is normally a nitrogen loss (Fig. 8.10), particularly with the superduplex grades. 10 However, additions of a few per cent of nitrogen to the shielding gas can result in an increase in weld metal nitrogen content. 11–13 For the 22%Cr grades (S31803/S32205) this equates to some 0.5 to 1.5

CO2 Analyzers | Nova Gas | Carbon Dioxide Gas Analyzer

Carbon dioxide is a gas of interest in many analytical applications. Infrared detectors, also known as NDIR analyzers, can be used to measure CO2 because it is an excellent absorber of infrared energy.Carbon dioxide can be measured in percent (%) and parts per million (ppm) depending on the requirements of the application.

Characteristics of Toxic Gases - Crowcon Detection

At the point of exhaust, nitric oxide accounts for about 90% of NOx. However it reacts spontaneously with oxygen in the open atmosphere to produce nitrogen dioxide. Nitric oxide is a colourless gas but nitrogen dioxide is an acid, pungent smelling, brown gas. Ozone: 1.6: O 3: Ozone is an unstable gas, and is generated as it is required. It is

Flue Gas & Emissions Analyzers | Nova Gas | Portable

A flue gas analyzer will enable you to measure the concentrations of various gases and adjust burners on a boiler to help achieve optimal combustion. Efficient combustion also reduces emission of pollutants such as nitric oxide (NO), nitrogen dioxide (NO2), sulfur dioxide (SO2), and particulate matter.

Nitrogen Syngas 2021 - crugroup.com

This "green" hydrogen can be used for production of ammonia or methanol which then comes without emission of CO2. Both these products can further be processed to fertilizers or other chemicals, but can also serve as fuel or for energy storage. Concepts for such applications have been presented at earlier Nitrogen + Syngas Conferences.
