Nitrogen Purging Services

Nitrogen Purging Services

Nitrogen Purging is widely used in the petrochemical industries to remove clogged gases and materials from large pipes offshore. Nitrogen represents the optimum solution in terms of neutralising the pipelines, facilitating the transportation of other gases safely. It can also facilitate the maintenance of pipelines on a timely basis.

    • The process of treating hazardous or challenging environments that have been subjected to highly reactive oxygen levels.
    • Nitrogen is introduced at a high pressure to reduce oxygen content within an environment and subsequently reduce the risk of explosive reactions due to the presence of hydrocarbons.
    • Supply process plants that can deconstruct and reconstruct desired environments by replacement of air (oxygen freeing) and removal of volatile fluids.
    • Vital for plant shutdowns when Oxygen levels become dangerously high.


    • Nitrogen purging can be employed during the commissioning of a process plant, or during start-ups, turnarounds or shutdowns
    • Displacement & dilution are the two most common forms of purging, depending on the configuration and design of the plant
    • Liquid nitrogen is vaporised and pumped at dew points approaching -65°C. This is ideal for drying water-sensitive process systems/pipelines
    • Pipeline maintenance, product change out or inventory displacement can be delivered safely and economically with our high-pressure, variable flow mobile pumping units
