How to Remove Water and Mechanical Impurities from Diesel Fuel?

The Contamination Process of oil products traces its roots to oil refineries and accelerates at each subsequent stage of the petroleum’s life cycle.  The concentration of pollutants in an automobile fuel tank can reach up to between 0.04 to 0.06 g/kg (for gasoline) and 0.15 to 0.6 g/kg (for diesel fuel).  It is also nearly impossible to prevent water from getting into petroleum products.

Watering occurs due to the tanks “breathing” during the period of storage as well as from condensation of moisture from the air.  Water therefore, can remain in fuel in both a dissolved or an emulsified form.

Emulsified water has the most dangerous influence on the performance characteristics of petroleum products.  The formation of water-fuel emulsions, which can occur for any reason at an oil refinery, will inevitably lead to significant financial losses.

Water contaminated petroleum products can cause:

  • corrosion of equipment;
  • product loss during the process of tank drainage;
  • excessive preparation time of raw material, intermediates and finished products;
  • freeze damage of equipment in winter time; and
  • decreasing of the catalytic process efficiency and reduction of catalyst service life.

Today various processes and machines are used in industry, and their operational principles are based on both traditional (influence of gravitational and electric fields, chemical treatment, filtration through special baffles) and modern approaches (ultrasound and magnetic fields effect).  As a general matter, the necessary quality of petroleum products is achieved through usage of the full range of measures aimed to remove all or the majority of impurities.

Cleaning mechanical admixtures with the help of various filters is one of the most common methods of controlling contamination in oil products.  Centrifugal separators can be used to remove water and mechanical particles.  Corrective Maintenance however, can be a quite problematic and time-consuming process. Additionally, corrective maintenance can be very expensive.

The efficiency of coalescence filters, subject to the presence of large amounts of mechanical impurities in feedstock, leaves much to be desired.

The problem of purifying light petroleum products can be solved most effectively using GlobeCore UVR-type plants.  GlobeCore equipment is suitable for diesel fuels, transformer oils, hydraulic oils and industrial oils and can clean and remove free and dissolved water and mechanical impurities as well as water-soluble acids and alkalis.

Porous polymer compositions are used as the filtering materials for UVR plants.  They were tested for the first time back in the 1970’s, and even at that time they were proven to be reliable water and mechanical impurity retainers.  Effective purification is achieved due to the filtering material’s volume as well as the filtering material’s tortuosity.

One of the main advantages of the UVR plants is the filters’ recoverability.  UVR filters can be used multiple times before replacement is required.

The machines are divided into two groups according to the type of the filter element installed and used by the machine:

  • equipment that provides purification by removing mechanical impurities only;
  • equipment that provides purification by removing free and dissolved water as well as mechanical impurities.

When using the GlobeCore UVR plants, you can provide diesel fuel of high quality as well as the reliability and efficiency of the equipment in which this fuel is used.
