Liquid gas supply



Select a step where Air Liquide intervenes in your value chain.

Pressure transfer and purging

Oxidation occurs during liquid transfer from one tank to another. Pressure transfer and pipe purging using nitrogen or carbon dioxide consists of using slight over pressure with the gas in a tank, vat or pipeline, to push or flush out the remaining liquid or air while inerting the pipeline and preventing risks of oxidations.

The gas solution is natural, effective, fast, accurate, well controlled for protecting liquids from oxygen pick-up during their transfer from one tank to another and with little investment required.
