Wet-layup protection with nitrogen blanketing is a proven method for protecting against and avoiding corrosion in your boiler circuit using the South-Tek Systems N2-GEN nitrogen generator series.
No longer need to use tube trailers, costly demurrage charges, cylinder maintenance, and storage. Generate the nitrogen for your application ANY TIME you need it and REDUCE COSTS. Real ROI that can be proven and delivers actual savings to your annual maintenance budgets!
Problems related to improper layup include general corrosion, which contributes to elevated iron levels in boiler water, and pitting corrosion that can lead to the cracking of pressure parts and waterside leaks. Inadequate layup can also compel operators to extend startups to meet chemistry specifications.
The Solution – South-Tek Systems – N2GEN Nitrogen Generator utilizes state-of-the-art PSA technology. By converting compressed air readily available from the plant supply, our N2 Series delivers a concentrated nitrogen output stream. With an integrated PLC-based control system, we ensure the plant receives nitrogen with a purity ranging from 99.6% to 99.999%.
The N2 Series generator provides a nitrogen blanket capable of preventing oxygen ingress and improving the overall cycle chemistry. EPRI recommends a minimum of 99.6% nitrogen purity for wet layup, which can be easily accomplished with our system.
During periods of fuel-pipe inerting, the generator can easily be set to purge any pipes in the plant, eliminating the need for bulk nitrogen storage or cylinders. A quick connection to the nitrogen-generator outlet with a standard hose reaches any fuel-pipe tap necessary to inert the entire system before maintenance.
The Result: The nitrogen generator has enhanced overall cycle chemistry by decreasing iron deposition in the boiler and HRSG units caused by surface corrosion.
In addition, key startup chemistry can be achieved much faster following a boiler layup with a nitrogen cap than without it. Other benefits include the following:
- Improved overall cycle chemistry by reducing iron deposits caused by surface corrosion
- An EPRI key initiative – Achieve optimum and key startup chemistry much faster following a nitrogen boiler layup.
- Reduced nitrogen bulk, storage, and rental costs by utilizing onsite production.
- The risk of employee injuries is linked to the handling and maintenance of high-pressure cylinders and the need for additional storage space.
