ExxonMobil Research and Engineering (EMRE) announced that Imperial Oil's refineries in Dartmouth, Nova Scotia, and Edmonton, Alberta have selected ExxonMobil's proprietary SCANfining(1) process. This innovative technology will be used to achieve lower sulphur levels in gasoline required under the new Canadian Federal regulations. Imperial Oil is an affiliate of ExxonMobil operating in Canada.

This process has been commercially demonstrated in Bazan Oil Refineries' Haifa refinery, as well as in ExxonMobil's Baton Rouge, Louisiana and Port Jerome, France refineries. To date, the technology has been selected at 11 locations around the world, and further demand is anticipated. The SCANfining process selectively removes sulphur to greater than 95 %, while minimizing octane loss. SCANfining is based on process innovations that minimize the hydrogenation of octane-rich olefins, as well as a proprietary, selective catalyst (RT 225), jointly developed by EMRE and Akzo Nobel Catalysts.

A full range FCC Naphtha SCANfining process was chosen for the Dartmouth Refinery. The selectivity advantage of the SCANfining process and catalyst offers a simple approach to treating a full range FCC Naphtha stream while retaining product octane. The full range configuration does not require a catalytic naphtha splitter, thus reducing the capital and operating cost of a gasoline desulphurisation unit.

Strathcona refinery in Edmonton will also use SCANfining for treating an intermediate FCC naphtha stream. SCANfining, in combination with a "Sweetening Plus" configuration to treat light FCC naphtha, proves a low cost alternative to other extractive mercaptan technologies.

ExxonMobil is a leading global oil, natural gas, and petrochemicals company whose subsidiaries have operations in about 200 countries and territories.
