The customer needed to heat nitrogen gas from a 10°C (50°F) inlet temperature to a final outlet temperature of 760°C (1400°F) -- an increase of 750°C ( 1,350°F). An operating pressure of 100 PSIG (16.6 kPa) and flow rate of 0.105 to 0.15 pounds (0.048 to 0.068 kg) per second were also required. Due to the environment of the heating ...

Pure gases are classified by grade. The first digit of the grade classification indicates the 'number of nines' purity, e.g. N3.0 = 99.9% purity. The second digit is the number following the last nine, e.g. N4.6 helium has a guaranteed minimum purity level of 99.996%.

Nitrogen (N 2) gas packaging for fresh-cut vegetables (lettuce and cabbage) has been examined as a means of modified atmosphere packaging (MAP) for extending the shelf life of cut vegetables.Gas composition in enclosed packages that contained cut vegetables and were filled with N 2 had an oxygen (O 2) concentration of 1.2 to …

The natural gas quality characteristics associated with this new supply mix are and will be different from traditional domestic supply sources and will impact economic and operational practices on the interstate natural gas grid and may permanently alter business methodologies and regulatory tariffs.

Nitrogen is most suitable for high-current plasma cutters. It offers excellent cut quality for mild and stainless steel or aluminum up to 3 inches thick. Nitrogen is usually used as a stabilizer with argon to add a wetting action to a weldment while keeping the cost down. Nitrogen plasma works very well with CO2 as a secondary gas for better ...

Gas stoves are linked to childhood asthma. Cooking with gas stoves creates nitrogen dioxide and releases additional tiny airborne particles known as PM2.5, both of which are lung irritants. Nitrogen dioxide has been linked with childhood asthma. During 2019 alone, almost two million cases worldwide of new childhood asthma were estimated …

For nitrogen and oxygen gas generators – especially the latter – the use of a SenzTX oxygen transmitter is imperative for ensuring high-output gas quality and system operating efficiency. Fitted to the outlet phase of the gas generator, the SenzTX uses a non-depleting zirconia electrolyte sensor mechanism to ensure fast response times with ...

EPA's Integrated Risk Information System Profile for Nitrogen Dioxide. NO 2 acts mainly as an irritant affecting the mucosa of the eyes, nose, throat and respiratory tract.
