Filter Separators

Forain's range of filter separators is intended for those applications where a high efficiency removal of solids and liquid particles is required, regardless of their size. The use of these separators is the best solution to remove very fine mists or aerosols from the gas flow. Other applications include the removal of lubricating oil from process gas, entrainments in natural gas lines upstream compressor stations, reducing and metering stations, etc.


Principle of operation (FSO and FSV type)

In filter separators, removal of solid and liquid particles takes place gradually.
At vessel inlet, larger particles are removed by gravitational effect due to the gas velocity decreasing and by impingement on inner surfaces.
Filter elements entrap the smaller solid particles, while liquid droplets coalesce to be removed in the following stage consisting of a vane unit. The contaminant is collected either in a separate reservoir connected to the filter separator or in the same vessel out of the gas flow.
