The feed to a vapor-liquid separator may also be a liquid that is being partially or totally flashed into a vapor and liquid as it enters the separator.

A vapor-liquid separator may also be referred to as a flash drum, knock-out drum, knock-out pot, compressor suction drum or compressor inlet drum.

When used to remove suspended water droplets from streams of air, a vapor-liquid separator is often called a demister.

Where vapor-liquid separators are used

Vapor-liquid separators are very widely used in a great many indusries and applications, such as:

• Oil refineries
• Natural gas processing plants
• Petrochemical and chemical plants
• Refrigeration systems
• Air conditioning
• Compressor systems for air or other gases
• Gas pipelines
• Steam condensate flash drums
