Abstract
A multi-stage process for transforming a high sulfur ISO 8217 compliant Feedstock Heavy Marine Fuel Oil involving a core desulfurizing process that produces a Product Heavy Marine Fuel Oil that can be used as a feedstock for subsequent refinery process such as anode grade coking, needle coking and fluid catalytic cracking. The Product Heavy Marine Fuel Oil exhibits multiple properties desirable as a feedstock for those processes including a sulfur level has a maximum sulfur content (ISO 14596 or ISO 8754) between the range of 0.05 mass % to 1.0 mass. A process plant for conducting the process is also disclosed.
Claims8
A process for treating high sulfur Heavy Marine Fuel Oil for use as feedstock in a subsequent refinery unit, the process comprising:
- mixing a quantity of Feedstock Heavy Marine Fuel Oil with a quantity of Activating Gas mixture to give a Feedstock Mixture;
- contacting the Feedstock Mixture with one or more catalysts under reactive conditions to form a Process Mixture from said Feedstock Mixture;
- receiving said Process Mixture and separating hydrocarbon liquid components of the Process Mixture from any bulk gaseous components of the Process Mixture;
- subsequently separating any residual gaseous components and any by-product hydrocarbon components from the hydrocarbon liquid components to give a Product Heavy Marine Fuel Oil;
- and, discharging the Product Heavy Marine Fuel Oil, wherein the Feedstock Heavy Marine Fuel Oil complies with ISO 8217 (2017) and has a sulfur content (ISO 14596 or ISO 8754) between the range of 5.0 mass % to 1.0 mass %, and wherein said Feedstock Heavy Marine Fuel Oil has;
- a maximum of kinematic viscosity at 50° C. (ISO 3104) between the range from 180 mm2/s to 700 mm2/s;
- a maximum of density at 15° C. (ISO 3675) between the range of 991.0 kg/m3 to 1010.0 kg/m3;
- a CCAI in the range of 780 to 870;
- a flash point (ISO 2719) no lower than 60° C.;
- a total sediment—aged (ISO 10307-2) of less than 0.10 mass %;
- a carbon residue—micro method (ISO 10370) less than 20.00 mass % and wherein the Product Heavy Marine Fuel Oil has a sulfur content (ISO 14596 or ISO 8754) between the range of 0.50 mass % to 0.05 mass % and wherein said Product Heavy Marine Fuel Oil has:
- a maximum of kinematic viscosity at 50° C. (ISO 3104) between the range from 180 mm2/s to 700 mm2/s;
- a maximum of density at 15° C. (ISO 3675) between the range of 991.0 kg/m3 to 1010.0 kg/m3;
- a CCAI in the range of 780 to 870;
- a flash point (ISO 2719) no lower than 60° C.;
- a total sediment—aged (ISO 10307-2) of less than 0.10 mass %;
- a carbon residue—micro method (ISO 10370) less than 20.00 mass %.
