Gas generation is really kind of a misnomer; technically what is commonly offered in the low pressure applications is gas separation. The process is much more akin to filtration. By molecular sorting or differentiation due to the sizes of the gas molecules, one can expect to get a reasonable amount of flow of the gas that they are looking for in high purity concentrations.

Flows as high as 3500 standard cubic feet an hour can be easily achieved with modern membrane technology. For larger systems with higher flow requirements, the more common method is through adsorption of the unwanted gases, most commonly with a carbon molecular sieve adsorption bed. Operation of these pressure swing adsorption units is similar to that of a standard desiccant dryer. Especially for blanketing gas operations, generating your own nitrogen tends to be considerably less expensive than purchasing and using liquid nitrogen. We have been involved in many of these systems and as such offer our experience to assist you in your endeavors to achieve the more cost effective means for your facilities operational requirements.
