Supplying High Quality, Premium Residual Fuel Oil for the Shipping Industry

Rigby’s solution to IMO 2020 is rooted in traditional refining hydrotreating processes. Our solution is unique because it focuses on removing sulfur and other environmental contaminants from an ISO 8217 compliant high sulfur residual marine fuel, which is widely available in the market today, to produce an ISO 8217:2017 compliant Very Low Sulfur Fuel Oil (VLSFO) or Ultra-Low Sulfur Fuel Oil (ULSFO). The Rigby Process™ is counter to other refining upgrading processes in that our process is designed to minimize cracking and hydrogenation while maintaining the desired bulk fuel properties and maximizing production of Rigby Fuel™ (VLSFO) or Rigby Fuel (ULSFO).

Feedstock to the Rigby Process is ISO 8217 compliant HSFO that is currently produced through efficient and existing commercial routes. Rigby Fuel (VLSFO) is expected to be a preferred fuel of shippers with superior properties to blends, distillate-based fuels and other low sulfur marine fuel options as the bulk properties of Rigby Fuel (VLSFO) are consistent with the HSFO currently used by shippers. Rigby Fuel does not require additives and has properties superior to HSFO currently available to shippers. Rigby Fuel has very low metals content, reduced asphaltenic content, no cat fines; it is homogenous, stable and miscible. Other chemical contaminants which have caused major problems for ship engines are also removed by the Rigby Process.

Commercially, the Rigby Process is a significantly lower priced alternative to any variety of hydrocracking, coking and other residual upgrading options. When compared with the available information on competitive technologies, the Rigby Process Unit is a much faster option to market as either stick-built or fully modular (or some combination thereof) with a significantly lower CAPEX and OPEX.

Rigby Refining has completed multiple successful pilot tests utilizing feedstocks with sulfur content between 2.4% and 3.3%. The fuel oil produced is ISO 8217:2017 compliant with a sulfur content of less than 0.5%. Rigby has also demonstrated the ability to produce a 0.1% sulfur ISO 8217: 2017 fuel oil product which would be viable currently in Environmental Control Areas (ECAs).

Rigby Refining plans to build, own and operate multiple Rigby facilities globally. These plants will upgrade HSFO to ISO 8217: 2017 compliant 0.5% VLSFO, or 0.1% ULSFO.

Globally, over 100 million tons of HSFO is currently consumed annually and the industry needs a solution to address these stranded materials that will result from IMO 2020. The patent pending Rigby Process places Rigby Refining in the best position to maximize the opportunities of converting this abundant high sulfur feed into a ISO 8217:2017 compliant residual fuel at a low production cost.

Rigby Fuel (VLSFO) Property Data

Rigby Refining has conducted comprehensive analytical testing of the fuel produced in Pilot Tests. The results confirm that the Rigby Fuel VLSFO is ISO 8217:2017 compliant, while maintaining or improving the ISO 8217 properties. Additional testing shows that Rigby Fuel (VLSFO) has superior cleanliness, lubricity and ignition and combustion properties, making it a very desirable fuel for shippers. Rigby Fuel (VLSFO) is also compatible with both distillate (ULSD/MGO) and residual marine fuels (RMG 380/RMK 500). Rigby Fuel (VLSFO) was also tested after 57 weeks in storage and it maintained its ISO 8217 properties, cleanliness and stability even after a year in storage. In other words, Rigby Fuel (VLSFO) has unlimited “shelf life,” unlike many alternatives.
