Rigby Refining, LLC is a technology and licensing company founded in 2016. We aim to be the global leader in providing high quality, premium residual fuel to meet the shipping industry’s needs. Rigby’s technology foundation is an extensive portfolio of granted US patents with many more in process in the US, Latin America, and globally. The Rigby Process® was developed to address the IMO 2020 MARPOL Annex VI regulatory change that mandates a reduction of sulfur content in the global commons from a maximum of 3.5 wt% sulfur to a maximum of 0.5 wt% sulfur, while contemplating providing both the refiner and the ship owner / marine fuel consumer with an efficient and effective solution.
The Rigby Process is rooted in mature and commercially proven refining processes, utilizing an alternate approach to traditional refining practice and counter to the pursuits of traditional resid material upgrading. Our process feedstock is an ISO 8217 compliant HSFO or other residual materials to produce IMO 2020 ISO 8217:2017 VLSFO or ULSFO as a finished product, eliminating miscibility, compatibility, and stability concerns. With a small footprint and competitive lead time to operation, the Rigby Process can be integrated within a refinery or terminal to take advantage of existing infrastructure including tankage, docks, and utility systems. Rigby provides a lower CAPEX and OPEX alternative to traditional resid material upgrading with lower operating complexity and lower technology risk based on our patented processing approach.
