Preparation and Purification of Heating Oil

Today, heating oil is an easily available and a relatively cheap source of heat.  Sometimes in books and articles on relevant topics one comes across the term “pyrolysis oil”, which is derived from the name of the process in which it is possible to obtain this heating fuel.  Now heating oil has a tendency to displace some traditional oil products: kerosene, gas condensates, etc.  It has become possible due to the fact that heating oil generates large amounts of heat and does not have any unpleasant smell during combustion. Application of heating oil goes without arranging additional networks of fuel supply to the place of its direct use.  Do not forget also about the relatively low price.

Obtaining heating oil involves a petroleum feedstock distillation process.  The residual product of the process, in fact, is heating oil itself.  When comparing heating oil with diesel, it can be noted that it has a heavier fractional composition and higher viscosity.  Heating oil pour point is -5°C.  It is not enough to use this type of oil product in industrial environment, so in practice, special additives are added to heating oil to bring its pour point threshold to -26ºC.  This helps to reduce the pollution of filters with particles of solidified wax, as well as to increase the throughput of the entire length of the fuel supply line.

Among the other important properties of heating oil the following should be mentioned:

  • The absence of specific odor inherent to other petroleum products.
  • Minimal toxicity.
  • Good calorific value.
  • The possibility of using at low ambient temperatures.
  • Flash point of +40°C.

During prolonged storage, heating oil can be oxidized, contaminated with water and solid impurities, resulting in the loss of performance.  Application of the GlobeCore UVR-type plants can restore a marketable condition of the processed oil products, which includes removal of water and solids, clarification and removal of unpleasant odors.

The UVR-type plants offer the following advantages:

  • Ability to work in automatic and semi-automatic modes, which eliminates the constant presence of an operator, required only during starting and stopping of the plant and replacement of sorbents.
  • Low energy consumption.
  • Versatility of application.  When switching to another oil product, it does not require any complex manipulations.  It is enough to stop the plant, switch to manual mode, pump out oil products residues from the system, replace the adsorbent and filter elements.
