Bulk Diese Fuel Filtration
Bulk Diesel Fuel has a function to filter the fuel before it goes into distribution point, for this project fuel will be filtered by micro filter, oalesce and separator. Fuel will flow from inlet 6” and some fuel will flowing through icount PD. Icount PD is designed to detect solid particle that dissolved in fuel. There are 2 icount PD in this system, before and after the filtering process. From Icount PD we can see the different of contaminants before and after filtered. After icount PD fuel will be filter by diesel filter VF 4656 to removed solid contaminants on fuel. For the last filter process, there is water separator VV 2844 to remove any water contaminants from the fuel. After all filter process is done, fuel will flow to outlet 6” and ready to be used on unit.
There are six ways to operate service flow for this system: series, parallel, by pass, filter – 1, filter – 2 and micro filter. All process service flow can be adjust as the operator needed by close and open gate valve in the system

DFO Filter Cartridge
Diesel fuel is stored and transferred multiple times frim refining to dispensing. Preventative action does not always eliminate contamination. Common contaminants introduced during transportation include both extremely fine and abrasive silica as well as pipe scale. These contaminants can quickly deteriorate fuel quality below engine manufacturer standards, reducing the durability and performance of the engine.
Velcon’s DFO filters transform contaminated fuels to meet stringent downstream ISO 4406 cleanliness standards for the demanding limits placed on diesel fuel. The DFO design balances high surface area and depth filtration to maximize filter life which reduces filtration cost.

Clean Diesel Coalescar
As fuel is transported from the refinery to its point – of – use, it can quickly become contaminated from silica, pipe scale, and water condensate. These contaminants rapidly deteriorate fuel cleanliness far below engine manufactures minimum for fuel cleanliness.
Parker Velcon’s DI – 656D4TB coalescers in combination with DSO separators, contaminated fuels are cleaned to a level that meets stringent downstream fuel cleanliness standards for petroleum based diesel fuels.
The first stage in the DI oalesce removes particles through an inside-out flow and coalesces emulsified water into large droplets, which then fall to the housing sump. In the second stage, an outside-in process, the DSO separator creates a hydrophobic barrier to block the coalesced water droplets from flowing downstream of the housing. This multi-stage design assures the fuel is conditioned to a clean and dry state, ready for use.

Separator Cartridges
Parker Velcon DSO series separator cartridges for use as the second stage in filter/separator vessels to prevent water from re – entering the diesel fuel downstream. 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 coalesce cartridge.
