IN2ERT™ Accelerated Purging & Cleaning Service

Linde Services Inc. delivers safe, reliable, and fast cleaning using the IN2ERT™ accelerated cleaning and purging technology to maintain equipment containing hydrocarbon residues or volatile organics. The residues left in clearing tanks, piping, and heat exchangers emit H₂S and volatiles requiring suspension of maintenance activities.

The IN2ERT service provides asset owners a quick and efficient means to suppress toxins for maintenance work. With the IN2ERT process, the hydrocarbons are absorbed while the encapsulation of the internal contaminants and residues prevent further emission releases.

Hot Nitrogen for Catalyst Regeneration & Activation

Hot stripping with nitrogen reduces the concentrations of CO at elevated temperatures, thereby helping guard against toxic nickel carbonyl formation. Pure, dry, inert nitrogen also helps to free reactors of other contaminants and provides an excellent alternative to clean hydrogen.

The benefits of Linde's hot nitrogen process:

Cut downtime dramatically with accelerated drying and faster stripping
Pure, dry, inert nitrogen helps free the reactor of contaminants
When clean hydrogen is in short supply, nitrogen provides an excellent substitute

Hot Nitrogen Service Literature

Lower Explosive Limit (LEL)

Atmospheres with a concentration of flammable vapors at or above 10 percent of the lower explosive limit (LEL) are considered hazardous when located in confined spaces. However, even when a space contains or produces measurable flammable vapors below the 10 percent LEL, it might indicate that flammable vapors are being released or introduced into the space and could present a hazard in time. The Linde Services Inc. accelerated cleaning and purging technology address these concerns. IN2ERT technology lowers and stabilizes the LEL below 10% allowing for a clean entry into the vessels for repair or during re-commissioning.
