In-house nitrogen production for independence
When it comes to sourcing a nitrogen supply, companies are faced with the choice of producing their own or taking out a contract with a supplier.
There are advantages in producing nitrogen in-house; users get the purity, output and delivery f low that their specific processes call for. Depending on the particular use, this can be cheaper than having it delivered.
By doing away with liquid gas tanks on the factory premises, companies not only free up space but save considerable expense, since storing gas is subject to strict safety regulations.
Generators for in-house nitrogen production, however, pay for themselves within less than three years, depending on the purity of the nitrogen required. In addition, companies can monitor not only the purity, but the nitrogen quantity generated.
Boge is a system provider that offers users a complete package for generating nitrogen. The centrepiece of this all-round solution is the nitrogen generator selected from the N7P to N56P range.
Closely tailored to the nitrogen demand, it delivers purity grades of up to 5.0 (99.999 per cent). Besides the nitrogen generator itself, complete with system vessels and receivers to generate nitrogen, users also require a compressed air station made up of a compressor, refrigerant dryer, filtration, activated carbon adsorber and a compressed air receiver.
If the company already has a compressed air station, the generators can simply be connected to the existing network.
Thanks to its modular design, it is easy to expand or retrofit the generator on site. Up to two expansion banks can be connected to each master bank. Each bank, in turn, takes up to eight discrete easy-to-fit modules. The up to 24 modules that result provide f lexible nitrogen generation of between 1.3 and 265.8 Nm3/h.
Boge nitrogen generators are fitted with a basic control as standard supply. This can display two readings, such as the purity of the nitrogen and the quantity of nitrogen generated.
The generator can be rounded off with an optional microprocessor or touchscreen control to enable additional readings to be displayed.
The firm’s generators use the pressure swing adsorption (PSA) process to produce nitrogen.
