MSAR® is commercially and operationally proven in both steam boilers and diesel engines. It can be supplied directly from candidate refineries and delivered to a power plant using conventional infrastructure designed for heavy fuel oil.
Over 60 million tonnes of oil-in-water (OIW) emulsion fuel, branded Orimulsion®, was manufactured from 8° API Orinoco bitumen in Venezuela, and was subsequently fired worldwide in base-load boilers of varying sizes (50MWth to 770MWe). MSAR® is an improved version of Orimulsion® and the latest generation OIW emulsion, with a key difference being the technology can now be deployed in oil refineries and is applicable to refinery residue streams, as well as extra-heavy crudes. Key members of the Quadrise team worked in the original Orimulsion® business.
In 2008, a commercial demonstration of MSAR® as boiler fuel was successfully completed. MSAR® was produced at ORLEN Lietuva’s 200,000 bpd refinery in Lithuania and combusted at the 1,800MWe Elektrenai power plant owned by Lietuvos Elektrinė (LE), a previous Orimulsion® customer.
The commercial demonstration involved:
- Manufacture of >22,000 tonnes of MSAR® at the refinery, from Urals crude-based visbreaker residues, confirming the economic benefits of producing MSAR® versus fuel oil.
- A 20 t/h MSAR® Manufacturing Unit, which operated on a continuous basis, using a plot of less than 250m2 was installed in under 6 months.
- MSAR® was exported to the power plant by rail (~300km), using the refinery HFO rail loading system alongside regular HFO (or "Mazut") loadings.
