Your process and end-product quality can be directly impacted by contaminants and moisture. Inerting and blanketing help prevent the oxidation or contamination of substances by forming a protective layer of gas, by entirely or partially replacing the air around your product with gas to prevent moisture or oxygen from coming in contact with a reactive or flammable substance. Inerting with high-purity gas helps you maintain process and product quality, and improve safety and compliance with regulatory requirements.
What are your challenges?
Gas is most commonly used to form a protective layer, replacing air around or on top of the substance to keep moisture, oxygen or microbial growth or pests from coming in contact with a flammable or reactive substance.
Preventive inerting is the continuous maintenance and protection of an inert atmosphere within an area. This is generally implemented for installations where there is a permanent risk of explosion. Corrective inerting consists of injecting inert gas when an explosion risk is detected.
Selecting the right gas quality is the first step to improving your process. The quality of inerting and blanketing is directly attributed to the gas used. Airgas offers customized gas solutions using high-purity gases including argon, carbon dioxide and nitrogen that are free of oxygen, moisture and other contaminants. Our gas experts can help you define the best pure gas or gas mixture for your process, in the right quantity, plus equipment for any type of process including purging, blanketing, vessel pressure transfer, and more for most plant operations.
Keeping gas supply without runout is critical to your process. Airgas offers a variety of supply modes that are flexible and can grow with you. With one of the largest distribution footprints in the US, we can ensure reliable and quality gas supply, delivered when and where you need it.
