The Process

• Ultraclean use an oxidation/extraction process in order to reduce sulphur to ultra-low levels without necessitating hydrotreating.



• Due to the soft nature of the ULTREX™ process, it is able to be run at relatively low temperature and pressure thereby substantially reducing utility requirements.


• Oxidation is achieved by using a readily available oxidation media in concert with a specifically developed environmentally benign extraction catalyst. The purpose built extraction catalyst is used to extract the oxidized sulphur compounds from the hydrocarbon, and is subsequently regenerated for reuse.


• Given that our extractant has been specifically engineered around our application, as with any new chemical, there is always a regulatory process to go through before it can be used. This process has recently been completed for use within the US Toxic Substances Control Act (TSCA) registration.

ULTREX™ Process Control and Safety Automation

• The ULTREX™ process automatic safety and control systems are state of the art systems with both control system hardware and software being designed to comply with regulatory standard IEC 61508/61511 AK 6 SIL 3.



• The field intelligence and motive hardware devices are approved to operated in Zoned environments. These devices afford safe and unmanned operation of the process.



• This system, also by using appropriate security tools, allows us to constantly monitor the process from any remote location.
