The most striking impact of the catalytic process on Canadian upstream operations would’ve been eliminating the need for diluent for pipeline transportation.
Over 30percentage of almost any barrel shipped from Canada to North American refineries is a lowviscosity diluent. By chemically upgrading bitumen using this process, it can be possible to avoid the need for diluent for transportation. The upgraded bitumen will require less pipeline capacity and less pumping energy. This will have a positive impact on the cost of transporting bitumen and on related refinery operations. It’s a well refineries that utilize disadvantaged crudes like bitumen will see an immediate change in operations being that the reduction or elimination of diluent. Remember, less energy is necessary in order to separate the diluent, less storage is necessary in order to hold the diluent and fewer resources are vital if you want to manage the turnaround of the diluent.

Units that treat high sulfur levels, and the units downstream from them, would benefit from a more energyefficient desulfurization process that also reduces ‘heteroatom’ contaminants. Nearly almost any area of heavy unit operation benefits from using oxidation to remove heteroatoms, as this process is more costeffective than hydrotreating. The processing of bitumen and akin feeds with reduced sulfur, nitrogen and metals content will extend catalyst life in downstream treating units and will consume less FCC catalyst. Reducing the sulfur content of the feed by 80 -90percent will lower the operating costs of downstream units due to reduced hydrogen requirements, and it may also increase unit throughput.
Chemical upgrading reduces the mass percent in the high boiling point range, that will reduce coke make in FCC and coking units, thereby freeing up capacity.
Asphaltene content in bitumen was reduced by approximately 7percent. Other feeds will differ in levels of improvement, relying upon their chemical nature. Technical support services are provided to evaluate the upgrading potential for specific feeds of interest, since mostly there’s no body of performance data available to understand and model the impact on upgrading various kinds of hydrocarbons types with this ODS technology. These testing services provide performance and process data depending on both bench top and pilot scale testing. Therefore, these services also allow an organization to evaluate new feed strategies and refinery unit configurations.
Significant advances are achieved in oxydesulfurization process technology as an alternative to hydroprocessing. Therefore foremost, these advances lower the cost of transporting and processing bitumen. Generally, the technology can also be applied to heavy sour crudes and crude residues. HP
Seems like a packed bed reactor processing a crude oil or bitumen stream is still should be susceptible to particulate fouling from filterable solids in the oil.
