Diesel Oil Purification: Modern approaches

GlobeCore units are designed to purify, lighten, regenerate and remove aromatics from all types of diesel fuel and restoring it to a marketable condition and restoring its original performance characteristics.  Diesel fuel is acknowledged to be one of the most marketable oil products today due to such advantages as:

(1) relatively low price; and

(2) low fuel consumption rates.

Diesel engines have gained wide acceptance due to their reliability and efficiency.  As a result, millions of tons of such fuel are delivered to the world-wide market every year.  In speaking about diesel fuel, much attention should be paid to the problem of its contamination.  The use of fuel, containing different impurities, can lead to a rapid wear and damage of engine components and the entire fuel system.

If the fuel products are stored improperly, one oil product may penetrate into another one.   Even a small amount of foreign fuel may be sufficient to make the whole batch of diesel fuel unserviceable.  Fuel therefore, It is therefor, must be purified to avoid potential harm to engines and fuel systems.

The choice of the fuel purification method depends on the type of the contaminants and the way they get into diesel oil and fuel.  For example, modern vehicles are equipped with special filters.  First, diesel fuel is drawn to the fuel pump and runs through the special fine mesh filter. Then, diesel fuel is supplied to the pump that performs the function of a high-pressure regulator.   There may also be another device for diesel fuel purification – the coarse mesh filter, used to retain larger dirt particles.  Often, it is fixed at the bottom of a fuel pump.  Filter parts are usually situated in a transparent body since they are  also used for water separation.  Moisture will be visible and then must be be removed.

Some companies have a double fine mesh filter mounted: one part retains large particles and the other – particles that are less than 2 microns.  If paraffin happens to get into diesel fuel, the filters should be replaced.  Usually, there are two filters mounted into the vehicle: a  coarse mesh filter and a fine mesh filter.

The coarse mesh filter is also called a “sump” which is usually secured next to the fuel tank.  The fine mesh filter is fixed between the fuel injector and the fuel injection pump.  The coarse mesh filter can retain such impurities as metal particles, sand, rust or non-soluble oils.  The size of the particles should be more than 0.005 millimeters to provide effective filtration.  As a rule, filters are made of special brass moulded plates with calibrated slots that retain large contaminated particles.  The fuel purification methods, listed above, are performed directly on the vehicle.

You may be asking, what if there is a great amount of contaminated diesel fuel that has become contaminated and degraded and can no longer be sold or placed into the market?  This case requires a slightly different approach that consists in applying the benefits of the GlobeCore UVR line of units.  The GlobeCore UVR lines provides for the purification, lightening, regeneration and removal of aromatics from all types of diesel fuel.  As a result, the oil product is able to meet all the performance characteristics necessary for its further commerical use.  Additionally, it is very important that purified diesel fuel does not get dark if it is stored for a long period of time.

GlobeCore’s equipment is an optimal solution to many problems that arise at industrial enterprises, petroleum storage depots and refineries!
