  • Purging / De‐Gassing:

Nitrogen purging is the replacement of an undesired atmosphere by the inert gas nitrogen. During the commissioning of a process plant, the replacement of air by purging with nitrogen is known as “oxygen freeing” or “startup purging”. During a turnaround, the replacement of a hydrocarbon atmosphere with nitrogen is familiarly known as “degassing” or “shutdown purging”.

  • Nitrogen/Helium Leak Detection:

Leak detection on process systems using helium and nitrogen gas is the most accurate and quantifiable method. On an offshore production platform module, or within a petrochemical complex, the elimination of hydrocarbon leakage is of operational priority and importance. Such containment loss can lead to hazardous situations, environmental impact, and huge financial loss.

  • Pipeline Pigging:

Whether you’re performing major maintenance or remedial treatments on your pipeline, using nitrogen as an inert propellant for moving “pigs” through your pipeline makes good sense. Nitrogen is the gas of choice to displace oxygen, retard oxidation, break the “fire triangle” and prevent explosions.

  • Hydrostatic Testing:

Here at PPC, we will provide our customers with professional technicians to perform a hydrostatic test. We will furnish all equipment necessary to prove, clean, fill and test the line. We will also provide the compressors, dryers, and pigs to dewater and dry the line.

  • Dewatering:

After a successful hydrostatic test, water must be removed from the pipeline prior to the introduction of the product. While this is sometimes performed by displacing the water directly with the product, in most cases, the water is removed separately by dewatering with air. This is particularly the case where complete drying is required.

  • Nitrogen Fracking:

Gaseous nitrogen can provide performance and cost advantages over water‐based fluids in certain formations. Although water‐based fracturing fluids are widely used for hydraulic fracturing because they are inexpensive and offer good proppant transport into the fracture, they do have drawbacks. Water‐based fluids are unsuitable for water‐sensitive formations because they can cause water saturation around the fracture and clay swelling, which may significantly hinder the mass transport of hydrocarbons from the fracture to the wellbore.

  • Gas Lifting:

Nitrogen is used in well applications to reduce the weight of fluid in the wellbore. Nitrogen is pumped through coil tubing (or gas lift tubing) and discharged at the well perforations. As the nitrogen gas flows up the production casing, it expands and reduces the weight of fluid in the column, allowing the well to flow.
