Inerting

In process engineering, gasation refers to the introduction of a gas into a fluid, a bed of bulk material or a vessel in order to facilitate mass transfer, enable chemical or biological reactions, or specifically influence the atmosphere. Examples include the dispersion of oxygen in fermenters, the injection of gas into liquids for gas-liquid reactions, or the flooding of rooms with gas for pest control.

In the context of amixon® powders and mixers, the term ‘gas flushing’ is primarily used when the mixing chamber or the product is flooded with an inert gas (e.g. nitrogen or carbon dioxide) to displace oxygen and prevent oxidation or the formation of explosive atmospheres. Such inerting gas flushing is typically carried out via defined gas nozzles or connections. The pressure, gas volume and purging cycles are selected so that the desired protective gas atmosphere is established reliably and reproducibly.
