Supercritical Fluid Extractions

Sealing Solutions for Supercritical Fluid Extractions

Discover Spring-Energized Seals From North Coast Seal

When your operations involve supercritical fluid extraction, the process of separating one component from another using supercritical fluids as the extracting solvent, you need strong sealing solutions. Supercritical fluids are different from other solvents: These fluids are at a temperature and pressure above its critical point, but still below the level of pressure needed to compress the substance into a solid. North Coast Seal knows that working with supercritical fluids puts different demands on your seals. That’s why we offer spring-energized seals that provide gas-tight sealing capabilities—delivering durable and reliable sealing under extreme conditions.

Supercritical Fluid Extractions in the Food Industry

Spring-Energized Seals Built to Perform Under Pressure

From the separation of lecithin from oil to the extraction of spices and decaffeination of tea or coffee, there are many types of supercritical fluid extractions in the food industry. Depending on your operations, extraction equipment may range from entry-level extractions to research-grade systems used in laboratories. No matter your operations, there is one constant: the need for seals that can offer increased durability and longevity. The use of CO2 in the extraction process can cause swelling, and spring-energized seals provide optimal pressure handling. They offer a better performance than polymer-based seals and elastomeric seal materials. 

Spring-energized seals offer:

  • High tolerance for frictional, temporal, pressure, or chemical resistance
  • Resistance to chemical swelling when in contact with fluids or water
  • Tolerance of –268° C to over 260° C (when made with PTFE)
