After the initial cleaning of flue gas in an inert gas system, the gas is passed through what device for final cleaning?

The final cleaning of flue gas in an inert gas system involves passing it through a demister. A demister is specifically designed to remove droplets of liquid and particulates from a gas stream, which is crucial in ensuring that the gas is as clean as possible before it is either released into the atmosphere or used further in the system. In the context of inert gas systems on tankers, ensuring that the gas is clean is vital for safety and compliance with environmental regulations.

While scrubbers, dust collectors, and separators are important components in various gas cleaning processes, they serve different primary functions. Scrubbers primarily focus on the removal of gases and vapors, dust collectors target solid particles, and separators are used to divide different phases or components based on their physical properties, such as density. The role of the demister is more tailored to capturing fine liquid droplets, making it the most appropriate choice for the final stage of cleaning flue gas in this system.
