Due to the restrictive regulation on sulphur content imposed recently to Maritime Transportation (especially in the ECA areas), to the lack of fuel with low sulphur in the market (which prices increased) and to the need of restricting the SOx emissions caused by the oxidation of sulphur in fuel (also verified in shore industries), it was urgent to find a solution to this problem.

With this innovative solution, users can reduce the sulphur content of their fuels to levels allowed by the regulations at same time that it remains its desirable characteristics (thermal, physical and chemical).




The process requires no modifications to the installations, since it can be installed “In-Line”.
It is also easily adapted to different production capacities and flow rates.
And it is able to be implemented aboard ships, allowing them to burn fuel with the appropriate Sulphur content. By-products can be treated as oily waste by dedicated on-board systems and dispensed in the usual way.



The process requires the addiction of only a few components to the fuel (cheap, easy to obtain and recoverable in the process), and operate at reasonable operatory conditions (Low Temperatures and Atmospheric Pressure).

The process takes into account the oxidation of sulphur species presented in fuel to oxides and peroxides that are easier to remove. The oxidation process occurs efficiently due to the presence of an oxidant produced in situ and do the effect of ultrasound system that create cavitation and promote the thermal ionic dissociation of the water presented in the fuel.

A phase separation step allows the remove the undesirable components from fuel (sulphones, that are Sulphur oxides and peroxides), obtaining in the end a treated fuel with low sulphur content.



DESulphur Target
DESulphur can be used on a global scale, with special interest in countries with seaports.

It can be applied within to the maritime sector, as an alternative to other conventional desulphurisation solutions, delivering greater economic, energetic, operational/safety and environmental advantages.

  • Petroleum industry;
  • Waste treatment and recovery of fuels;
  • Fuel producers;
  • Global industries that use Heavy Fuel in their activities and systems/installations;
  • Naval sector.


Economic Advantages


  • Oxidant agent produced on the process. No need to add external compounds;
  • Process does not require significant amounts of energy (low production cost);
  • Reagents used are not expensive and easy to obtain;
  • Uses low temperatures and low pressures (comparing to HDS for exemple).
Security Advantages


  • The developed process doesn´t present any harm in terms of storage and Handling;
  • Reasonable operative conditions.
Environment Advantages


  • Process compatible with low flow, it can be implemented aboard ships, allowing them to burn fuel with the appropriate content of S. By-products can be treated as oily residues by dedicated on-board systems and dispensed in the usual way.


In addition to the Desulphurisation Technology, TecnoVeritas developed other technologies for fuel treatment and emissions control. See related products and services:
