 2.General Function

Separator Cartridges are employed as the second stage in filter/separator vessels. Their sole function is to repel coalesced water drops produced by the first stage cartridges while allowing hydrocarbon fluids to pass through. Water drops settle into the filter/separator sump and are not carried downstream. All particle filtering is done by the first stage coalescer cartridge.

3.How Separator Cartridges Work

Flow direction is from outside-to-inside. water being repelled by the hydrophobic separator medium on the cartridge’s

outside surface. Hydrocarbon fluids, on the other hand, easily pass through and exit the separator cartridge. Cartridges

with three different types of repelling media are offered:

Teflon Coated Screen (TCS) Cartridges 

are, by far, the most popular type of separator cartridge. With proper cleaning and inspection , cost effective TCS elements can be reused over many coalescer cartridge changeout cycles.
And, TCS cartridges generate considerably less static charge than pleated paper cartridges. These features have made them the preferred choice for aircraft fueling applications.

Pleated Paper Cartridges 

cannot be reused and are replaced at every coalescer cartridge changeout. They are often used with diesel and other fuel oils which may contain materials that adhere to TCS cartridges and cannot be cleaned off.

Synthetic Media Cartridges 

can be cleaned a maximum of two times. They are intended for customers who do not want to take the time to clean separators.

4.SeparatorCartridge Performance
Maintaining a uniform flow along the length of the cartridge optimizes performance and reduces the number of cartridges required. Flow is controlled by a tube, inside each cartridge, through which the hydrocarbon fluid exits the cartridge and the filter/separator vessel. Two styles of inner tube are offered. See bottom photo.
Cartridges with uniform hole pattern inner tubes are adequate for many applications. However, where optimum flow distribution is required, cartridges with variable hole pattern inner tubes are recommended. When converting older equipment, a lesser number of variable hole pattern cartridges is usually required. Operating costs will therefore be reduced.
