Frequently asked questions

Nitrogen Pressure, Flow rates & Purity

No, only flow rate affects purity.

Flow rates can be sustained continuously 24 hrs/day.

Max pressure is up to 28 MPA.

Max flow rate of a single unit is up to 50 scm/min or by combining units flow rates exceeding 100 scm/min can be achieved.

Purity ranges from 95 – 99%

Onsite nitrogen generation eliminates the logistical challenges and costs of transporting bulk nitrogen to a location

Nitrogen Drilling

Nitrogen drilling is the process of using nitrogen to eliminate the risks associated with hydrocarbon-producing formations. Nitrogen displaces oxygen, preventing fires, combustion, and dangerous reactions between oxygen and hydrocarbons. To a lesser extent, nitrogen is also used to reduce corrosion issues.

We offer onsite nitrogen generation services for:

  • Nitrogen inerting
  • Nitrogen gas lifting
  • Nitrogen well cleanouts
  • Plant turnarounds
  • Plant purging
  • Plant commissioning
  • Pipeline pigging
  • Smart pigging
  • Pipeline and vessel purging
  • Pipeline and vessel drying
  • Well abandonment
  • Pipeline and vessel abandonment
  • Plant abandonment

Some benefits of using nitrogen in drilling are lower operational costs, increased worksite safety, quicker startup times, better purity levels, no delays, no production loss, and reduced carbon footprint.

Nitrogen Purging

Nitrogen purging is the process of displacing hazardous or unwanted gases and other impurities to create an inert atmosphere. While other types of gases can be used for pipeline purging, nitrogen is the preferred method due to its high purity levels and efficacy.

Nitrogen purging is required to routinely “cleanse” pipes and other systems of oxygen and moisture. Many industrial processes require an oxygen-deficient environment for safety, quality control, and to prevent damage from oxidation. This is where nitrogen purging is applied.

There are four essential types of nitrogen purging systems: dilution purging, displacement purging, pressure-hold-vacuum method, and pressure liquid transfer. The right system depends on the application of the industrial equipment, operator requirements, and the company’s preference.

Nitrogen Drying

Nitrogen drying is the process of removing moisture from pipes and other systems. Nitrogen is used to reduce the risk of explosion, and the moisture is removed using a closed loop.

Some methods for drying pipelines include nitrogen gas, super dry air, vacuum, dehydration, internal sandblasting, and methanol batching. Nitrogen is the preferred method to help industries reduce their carbon footprint and increase safety for their workers.

Any water that remains within the pipelines will cause rapid corrosion and can compromise the purity of the fluid that travels through them. Pipeline drying is important to minimize corrosion, prevent impurities, and ensure pipelines function as efficiently as possible. Nitrogen pipeline drying is used to eliminate the risk of combustion, displace oxygen, and prevent fires.

Nitrogen Cooling

Nitrogen cooling is the process of using nitrogen to cool reactors during the shutdown process before maintenance work.

Nitrogen creates an inert atmosphere and prevents combustion. Nitrogen is also a cooling agent that can reduce the amount of time it would take the unit to cool down.

Nitrogen Pressure Testing

Nitrogen pressure testing is the process of using nitrogen when testing the pipeline before its first use. This is a crucial step as it determines whether the assembled pipeline can withstand the rigours of operating at full capacity. Pressure testing analyzes parameters such as maximum capacity, pressure ratings, leak checking, stability of the joints, and component reliability.

Nitrogen creates an inert atmosphere and is low in moisture content. Nitrogen eliminates the issues associated with using air or water for pressure testing and is a cost-effective method for pressure testing.

The component will first need to be isolated from the rest of the system that is not included in the test. We then connect our onsite nitrogen generator to the component, releasing nitrogen to alleviate the pressure. Nitrogen purges the system of any air, debris, and other contaminants while checking for leaks.

Nitrogen Gas Lifting

Nitrogen gas lifting is the process of using nitrogen to help restore satisfactory pressure to wellbores. Over time, natural formation pressure declines and begins to reduce productivity. Recovery methods like nitrogen gas lifting are used to achieve improved pressure within the oil wells.

Using onsite nitrogen generators, we channel nitrogen gas through tubes into the reservoirs, removing the accumulated liquids that are disrupting productivity. This is a fairly straightforward process that eliminates the risk of combustion. Onsite nitrogen generators can deliver 95-99% purity and a consistent flow.
