Oreco NitroGen™ - on-site Nitrogen generator solutions for tank blanketing

The inert properties of Nitrogen™ makes it widely used in the oil and gas industry. Nitrogen is odourless, non-polluting and non-reactive in nature – and that makes it highly suitable for storage tank blanketing.

At Oreco, you can get on-site Nitrogen generators, the NitroGen, specially designed for tank blanketing purposes. The generators are based on the PSA (Pressure Swing Adsorption) technology.

Nitrogen means greater safety
Safety is a top priority in the oil and gas industry. Nitrogen ensures safety during e.g. tank cleaning operations and other situations where an inert atmosphere is needed. However, getting hold of Nitrogen is difficult and very expensive to many refineries, tank farms and offshore sites around the world.

Get nitrogen where you need it
Oreco NitroGen generators allow you to produce your own Nitrogen where you need it, when you need it. The mobile generators are easily moved to a new location for a new task – e.g. for storage tank blanketing. You can also chose to order a stationary plant.

Producing your own Nitrogen is easier and cheaper; facts which can give you a competitive advantage. Other inert gases than Nitrogen are costlier alternatives. An on-site generator from Oreco gives you 24-hour access to nitrogen – with a low-cost, environmentally friendly solution.
