Our Company

Ultraclean Technology has developed patented solutions (Ultrex®) for the separation of sulphur from diesel, marine fuel oils, light cycle oils, clarified oils/FCC slurry oils, and Group I base oils.


Increasing environmental awareness and corporate social responsibility is resulting in a profound movement towards environmentally friendly solutions for the world’s hydrocarbon requirements.


Global environmental regulations are demanding dramatic reductions in sulphur levels in fossil fuels, reducing the impact combusting fuel has on pollution, human health, and the environment. Governments across the globe are moving forward with mandates to reduce the sulphur content of both land and marine transport fuels.


Desulphurisation of high sulphur hydrocarbon products is achieved today using Hydro-Desulphurisation (HDS). HDS is a high pressure and high temperature process that requires substantial amounts of energy and hydrogen.


The Ultrex® solution does not require hydrogen or the high temperatures and pressures of the HDS process, resulting in a significant reduction in carbon footprint, is less capital intensive, operationally simpler, and safer to use.

ABOUT US: Welcome

The Sulphur Campaign

There is a global drive to reduce sulphur in transport fuels to reduce the impact combusting fuel has on pollution, human health and the environment…

  • Low sulphur fuel is critical to lowering direct emissions of particulate matter from on-road traffic​

  • While developed countries have reduced diesel sulphur levels to ultra-low-sulphur diesel (ULSD) (10-15 parts per million ), in developing countries average sulphur levels are still high

  • The UN Environmental Programme is continuing to push for a global increase in use of ULSD​



  • International shipping uses high sulphur content heavy fuel oil (HSFO). The HSFO traditionally in use was 2,700 times dirtier than land transport fuel​

  • The International Maritime Organisation (IMO) estimated that sea transport emitted ~ 940 million tonnes of carbon annually​​

  • In January 2020 IMO reduced the sulphur content permitted from 35,000ppm to 5,000ppm (in absence of exhaust sulphur capture systems), and stricter 1,000ppm limit in effect in emission control areas (SECAs)
