Industries that use cold boxes know the importance of keeping tanks insulated. Whether storing or transferring liquefied natural gas (LNG), hydrogen, nitrogen, and liquid oxygen (LOX), these substances are pressurized and need to be kept cold to stay in its dense liquid form while preventing any undesired reaction. Cryogenic perlite is often used as an insulator in these cold storage tanks. As a natural mineral, perlite helps block the transfer of heat to keep the area cold without the need for additional energy, making it a sustainable choice.

What is Cryogenic Perlite?

When perlite minerals are heated, they expand and form tiny glass bubbles of trapped air. This is what makes it an excellent insulator, since these bubbles prevent heat from passing through. In addition to insulation, mineral-based cryogenic perlite has the following benefits for the product being stored, the storage containers, the workers, and the company.

• Not susceptible to extreme temperatures
• Lightweight nature puts less pressure on containers
• Fire resistant
• Does not react with chemicals
• Does not degrade over time
• Easy to replace during maintenance

Proper storage helps to keep energy and gas infrastructure operating efficiently and cost-effectively while delivering the essential resources our society needs.

Uses of Cryogenic Perlite

Cryogenic perlite is available as loose-fill insulation for the following applications:

• Double-wall cryogenic-grade storage tanks and cold-boxes
• Containers for keeping essential equipment cold
• Insulating pipes used for cryogenic processes

These cryogenic processes are used across a wide range of industries from medicine to agriculture.

Installing and maintaining cryogenic perlite requires specialized equipment and training. The tiny, white expanded minerals are light enough to be blown in between storage tank walls or into cold boxes. Perlite can be expanded on- or off-site. The key is to keep the materials dry in order to maintain perlite’s insulating properties. Any leaks or condensation in the pipes or containers can reduce the mineral’s effectiveness. Therefore, it’s important to inspect equipment on a regular basis.

Companies can have cryogenic perlite delivered to facilities in bulk trailers and installed on the jobsite. It’s also available in bulk bags delivered by freight. Bulk delivery is more efficient for quick, direct installation in large tanks, where the bags are more practical for smaller jobs.
