Nitrogen purging and displacement (LEL and oxygen freeing)

Nitrogen purging services are essential when the required nitrogen supply exceeds a plant’s ability to maintain the high flow rate often required during shutdowns and other maintenance procedures. Nitrogen purging is highly effective for pipeline purges, product displacement, and process pipeline inerting. Our engineers can develop the most effective and efficient purging techniques for any plant or pipeline environment.

FourQuest Energy can design custom procedures for the removal of unwanted atmospheres by nitrogen purging, including the removal of hydrocarbons, oxygen, and other toxic or reactive gases. Our engineers will determine the optimum rate, temperature, and volume required to remove unwanted products in the safest and most efficient way possible. Because nitrogen is inert, it will not support combustion. Therefore, once a system has been purged using nitrogen, there is no risk of ignition within that system or pipeline. The nitrogen atmosphere reduces the corrosion caused by oxidation, making it ideal for preserving piping for prolonged periods without use.
