New Zealand’s largest chemical storage tank inerted with the world’s most advanced nitrogen-generating membrane
Given the complex logistics, safety risks and expense of liquid nitrogen, Steamtech were quickly convinced by the benefits of generating nitrogen on site. The Atlas Copco NGM 2000 nitrogen-generating membrane we ultimately proposed not only delivers an unlimited supply of nitrogen, it is also possible to adjust the pressure, flow, and purity according to each application. The membrane was driven by 4 high-pressure Atlas Copco compressors delivering approx. 4500cfm of compressed air at 24 bar and in turn, around 700cfm of nitrogen. And while capable of generating much higher levels of purity, the customer opted for an output of 97%: more than sufficient for guaranteeing optimum levels of safety and efficiency.
Extracting nitrogen from the ambient air is no magic trick. 78% of what we breathe is already nitrogen. And to boost that percentage, all it takes is a little science, some high-tech machinery, and the proven agility of the world’s most trusted service provider. In fact, once you know that Atlas Copco’s latest-generation nitrogen-generating membranes can easily deliver a constant and reliable flow of nitrogen on demand at up to 99.9% purity, it’s easy to understand why the tide is gradually turning and why generating nitrogen on site is now becoming standard industry practice.
Being able to offer an unlimited quantity of high-purity nitrogen created enormous added value for our customer. We are the only provider in the country with the right nitrogen generators suitable for this process. And with quality equipment comes quality results.
As far as the reliability of our equipment is concerned, the results of this project speak for themselves: “As a precaution, the customer also rented a backup nitrogen-generating membrane in order to ensure maximum uptime during the project,” says Simon. “However, this backup was not required; our equipment performed perfectly as we expected.”
And as for our service, the best proof of our added value is repeat business: “This is the third tank cleaning project we have worked on for this customer over the past last 12 months and as a result, both the EPC, Steamtech and Atlas Copco Rentals have become preferred suppliers for this application, with multiple projects in the pipeline.”
Which means we’ll have even more opportunities to prove just how potent a combination our renowned technology, expertise, and agility can be!
