Removal of Sulphur from Recycling-Diesel Fuel

Since diesel fuel will rise in price in the near future it will become quite expensive for the customer. Therefore its time to look for alternatives. But do they really exist?
The solution: Treatment of used oil and polymer waste
How does this method work?
The polymer waste or used oil is heated up to 400°C, forming the diesel oil This diesel fuel can not be used directly due to a specific problem:

Diesel fuel deriving from used oil contains more sulphur than permitted by European law.

Thus this method has to be abandoned in Europe? No, there is a solution existing:

The application of the Sodium Technology

The used oil is reacted with sodium dispersion prior to the crack process. In this step the organic sulphur compounds are destroyed and inorganic bound sulphur is retained in the residue. After finalisation of the sodium treatment step the oil is cracked as usual.
Advantages of the Desulfuration applying the Sodium Technology:
  • No alterations in the crack process necessary.
  • Most economic due to low price of sodium.
  • No release of sulphur dioxide.
  • No further pretreatment of used oil required.
