BITUMEN UPGRADING WITH ART
Bitumens extracted from tar sands and oil sands, as well as many of the very heavy oils, do not lend themselves to easy proeessinE in conventional refineries. The relatively hiEh Conradson Carbon content, as well as high levels of vanadium and nickel, p~esent considerable difficulties for catalytic hydroprocessinE routes. ProcessinE of bitumens and heavy oils in delayed or fluid cokers produces unsaturated products and converts substantial quantities of the feed to unwanted by-product coke.
The ART= Process which was initially developed by EnEelhard Corporation for upEradinE of petroleum residual feedstocks and poor quality etudes, is also applicable for upEradinE bitumens andvery heavy oils. This process is available for license throuEh The M. W. KelIoEE Company.
Reconstitution of the ART products produces a substantially improved synthetic etude (synerude) which can be processed in most conventional refineries. DependinE upon the quality of the feed to the ART unit and market requirements, it may be desirable to further improve the ART products by hydrotreatinE prior to reconstitution. Hydrotreatment produces hiKh yields of a high quality synerude which is equal to or superior to most world market crudes.
This paper presents the results obtained when proeessinE Utah's Sunnyside Bitumen in an ART pilot plant and the results to be expected when processinK Athabasca Bitumen in a commercial unit.
*ART is a service mark of Engelhard Corporation for professional services relat- ing to selective vaporization processes for removing contaminants from petroleum feedstocks.

THE ART PROCESS
The ART Process is a selective vaporization and fluidized demetallization and decarbonization process. The equipment utilized is similar to that used in fluid catalytic cracking,
¯ which has been proven over a period of forty Years. However, the operating conditions, contact time and type of fluidized solid differ from what would be seen in a modern FCCU. The ART Process uses the equivalent of a short riser/contactor and a fluidizable solid identified as ARTCAT:Ĉonversion, as defined in catalytic cracking, is maintained at a .considerably lower level than in
The ART Process, proven in commercial test units of 7000 and 10000 BPSD capacity, plus a 55000 BPSD unit operated by Ashland
Oil Co. in their Catlettsbur.g, Kentucky refinery, has shown its ability to process a variety of crudes ranging from atmospheric residues to vacuum bottoms containing as much as 90% asphalt.
The ART Process typically achieves the following results:
o Removes 95+ percent of the metals.
