Process Description - Refinery Final Products' Storage and Delivery
The major products of oil refining are: LPG, gasoline, diesel, jet fuel, fuel oil, and kerosene—a blend of several different streams produced by the various refinery processes to meet final specifications. These products are then stored in a tank farm on the refinery premises before being delivered to retail markets. Delivery may be via pipeline to area distribution terminals, or loaded onto tanker trucks for direct delivery to retail outlets.
Prior to leaving the site, the products are usually filtered and coalesced to remove solid contaminants and suspended water. Contaminants, such as rust and pipe scale can foul and erode distribution equipment (e.g. pumps, nozzles, flow meters) as well as end users’ equipment (e.g. engines, boilers). Water can also cause engine maintenance problems. Water in fuels often extracts highly corrosive sulfur compounds and chlorides exacerbating corrosion and plugging in engine injection systems or the engine itself.
Refinery Needs
- Achieve oil production quotas by meeting product quality particulate and water specs
- Achieve product specs without the need for expensive reprocessing
- Protection against corrosion and contamination of product transfer equipment
- Protection of end users’ equipment against corrosion and plugging
Production Challenge / Pall Solution for the Refinery Products Filtration
| Challenge | Solution |
|---|---|
| Meet particulate specifications for final products | Improve refinery productivity and ensure product specification by removal of particulates formed in storage equipment upstream of the distribution points.
|
| Guard against hazy final products leading to corrosion and plugging of end users’ equipment | Reduce corrosive nature of products by removing suspended water upstream of the distribution points.

Key Application/Filter Recommendations (other applications not shown)
| Diagram number | Application | Pall Product | Customer Benefit |
|---|---|---|---|
| 1 | Prefiltration prior to liquid/liquid coalescer | Low operating costs by extending L/L coalescer life | |
| 2 | Free water removal from fuels for shipment | AquaSep XS liquid/liquid coalescers | Reduced salt costs when downstream salt dryers are used
Elimination of interruptions and changeout costs due to replacement of disarmed coalescers
Low cost per gallon treated |
| 3 | Downstream of salt, desiccant or clay treatment | Freedom from off-spec shipments due to high solids levels |
