Protection of Burner Nozzles
|Fuel gas in a refinery or a gas plant is a mixture of off-gases from processes in the plant. Since these processes are vulnerable to upset conditions, the composition of the fuel gas is frequently changing. Fuel gas can contain high concentrations of condensable hydrocarbons and carried over amine. These liquids are in a fine aerosol form and very difficult to separate with knock-out drums or packed vessels. As liquids and solids enter combustion equipment, they foul burner nozzles and combustors. This results in frequent maintenance and replacement of the burners, poor burner efficiency and increased fuel gas consumption.|

- Pall Corporation's SepraSolTM Liquid/Gas Coalescer System Protects Burner Tips
A Pall SepraSolTM Liquid/Gas coalescer in the fuel gas line will remove virtually all of the entrained liquids in the fuel gas. SepraSol coalescers remove hydrocarbons, amine, or caustic aerosols as small as 0.1 micron. Most aerosols smaller than 5 micron are not separated in knock-out drums or packed vessels.
All of Pall’s SepraSol coalescer products contain a patented oleophobic/hydrophobic treatment which allows the coalescer to recover quickly and capture more efficiently slugs of liquid that result from the upset conditions that frequently occur in fuel gas systems. These treated coalescers are particularly beneficial in fuel gas systems which are operating in petroleum refineries and gas processing plants.
