“Is my gas purity adequate for my process?”
Industrial gases, such as nitrogen, hydrogen, and argon, for furnace atmospheres are characterized by their very high purity (>99.995% and above). For example, impurity levels for cryogenic nitrogen are 10 parts per million by volume (ppmv) oxygen or less, and 3 ppmv or less moisture (< – 90° F dew point). This purity is typically adequate for many processes involving a wide array of materials. Some materials, due to their high reactivity, may require gases with even lower levels of impurity, especially those supplied via bulk or tube trailer supply modes. Some facilities install in-line purifiers as an added precaution against impurities picked up from the houseline. In-line purification typically involves the removal of oxygen and moisture. Sometimes with argon supply, it is necessary to remove trace nitrogen impurities. The choice of purifier is dependent on the gas and the type and amount of impurities to be removed. If you are having a process issue that you think may be related to gas purity, please call Air Products at 800-654-4567. 

Proper atmosphere selection

Learn how you can reduce your cost, trouble shoot and improve your product quality through proper atmosphere selection and flow optimization.

Easy Tank Changeouts

Our engineering team provides fast and fully integrated tank system change-outs in as little as 3 days with no gas supply disruption. Our turn-key process makes switching easy for new customers. We bring in a temporary gas supply, coordinate old equipment removal with the former supplies and set our new equipment on the pad interconnecting all the piping. Finally, the tank is filled, put on-line and tested to make sure all systems are running safely and efficiently.

Optimize Your Furnace Process to Lower Operating Costs

We can perform on-site audits and atmosphere analyses that are as broad or as narrow as required by your facility, from comprehensive assessments of the entire gas supply system – storage tanks all the way through the piping to the individual use points – to reviews of the gas flow control, metering, and blending equipment, or the actual furnaces and process equipment that use the gas. Air Products’ team of industry focused engineers has the hands-on knowledge to help you identify ways to add value to your operations and lower your operating costs.
