Separating Hazardous Materials with Decanter-Centrifuge Systems: Sealed and gas-purged decanter-centrifuge systems can be effective for separating Class I, Div. 1-, or Class I, Div. 2-rated solvents and hazardous materials.

This article provides an overview of sealed and gas-purged decanter-centrifuge systems, which are used to separate hazardous materials and solvents. These systems are designed to prevent the release of dangerous substances and protect operators from explosions or toxic vapors. The article explains different purging methods and emphasizes the importance of creating an inert atmosphere inside the centrifuge to prevent combustion. It also highlights the need for redundancy in the inert-gas supply system to ensure continuous availability. The text discusses the use of inert gas blanketing to maintain safe operation and prevent the entry of oxygen or other gases. The system includes various components to maintain differential pressures and prevent gas leakage. Regular maintenance and testing are necessary to ensure the system's integrity. Centrifuges are efficient tools for continuous separation and find applications in various industries for explosion protection and environmental safety. [Extracted from the article]
