Amura Refining is on a mission to revolutionise the oil refining sector! As commercial partners of the sustainable and accessible patented Rigby Technology, we are passionate about promoting and helping implement smart alternatives that make better use of natural resources for a more sustainable industry.

Environmentally sustainable project

Our project is making a real difference to many environmental sustainability programmes around the globe. We're helping to reduce air pollution and promote the development of safe technologies for the environment, which is fantastic!

The situation

IMO 2020. The new International Maritime Organisation regulation bans the use of high sulphur fuel oil (HSFO) with a sulphur content of 3.5% and, from 1 January this year, sets a limit of no more than 0.5% in order to reduce sulphur oxide emissions from the global shipping industry.

Emission Control Areas (ECA). In these zones, the sulphur content limit is 0.1%, ultra-low sulphur fuel oil (ULSFO).

Current ECA zones include the Baltic Sea, the North Sea, several coastal areas of the United States and Canada.

The solution

Contrary to previous industry focus, The Rigby Process® allows for a smaller footprint (~2000m2) and less equipment.

Much lower complexity, CAPEX/OPEX than coking or cracking and much faster to market

Solves excess residue / HSFO balance in refinery or terminal

Allows refiner to maintain (or sour) their pre-IMO 2020 crude slate

Allows refiner to sell any residuals to market at a premium value

The Rigby Process converts HSFO into VLSFO (0.5% S) or ULSFO (0.1% S)

Utilising existing but stranded high sulphur marine fuel oil, no longer usable as a marine fuel without a scrubber, it is processed into IMO 2020 specification 0.5% sulphur very low sulphur fuel oil (VLSFO) or 0.1% ultra low sulphur fuel oil (ULSFO).

At 0.1% S, our product is a substitute for MGO in today’s ECA markets


80% reduction in SOx emissions
60% reduction in NOx emissions
