A first-time collaboration can sometimes have its hiccups, but Atlas Copco’s customer’s team didn’t have to hold their breath long. When a closed system needed purging, the company made sure the right Nitrogen Solution was on its way quickly!
Purging systems with Nitrogen
Nitrogen purging is necessary when an unwanted hazard or contamination has entered the closed system. Because Nitrogen is cost-effective, safe, dry and non-combustible, it’s ideal to displace the moisture or oxygen infecting a system. By creating a nitrogen atmosphere, the system can be purged. Two of the most common methods used to purge the closed system are dilution and displacement. Atlas Copco’s client used the NGM 750 membrane nitrogen generator to displace hydrocarbons on one of the plant’s columns to allow for a valve replacement work scope as they had identified a small weep from the valve. After these actions were completed, the NGM 750 unit was used for a pressure test. Working parameters were the following:
- Flow: 350m³/h flow
- Purity: 95,0 – 98,0%
- Nitrogen pressure: 9 bar
- Air pressure: 10 bar
- Air factor: 2,9
- Compressed air temp: 30
More than equipment
The NGM 750 membrane nitrogen generator allows for on-site nitrogen generation and, despite its size, it is easily adapted to your specific application. It is a sizable unit coming in at a little over five tons. However, it’s not any less flexible because it comes in a containerized unit. Easy to transport and easy to put in place. Even easier to get up and running because it’s electric driven.
Purity? You can say that again. The NGM 750 can deliver a 95% to 99% nitrogen purity to meet your nitrogen quality needs. Once on site, the NGM 750 is ready to go with minimal set up.
What is membrane technology exactly?
It’s not the membrane Cypress Hill raps about. In Atlas’ case, it allows oxygen, water vapor, and carbon dioxide to permeate the walls of the hollow fibers, leaving a constant stream of nitrogen. Purity flow, temperature, and pressure is adjustable and allow the membrane to generate nitrogen up to 99% purity.
The right tools and people for the job
The combination of Atlas Copco Rental equipment and its people proved to be the right solution again. Atlas Copco were able to not only meet but also exceed the client’s expectations! Nitrogen can be used for a variety of applications. From drying to tank purging, pigging and many more. Do you want to know more about Atlas Copco’s Onshore and Offshore Nitrogen solutions?
