  • Patent number: 8322200
    Abstract: The present invention uses the one or more on-line process analyzers that monitor the manufacture of petroleum products, such as gasoline or diesel fuel, to analyze and/or certify that the manufactured product meets regulatory and/or contractual requirements. The analysis is performed by re-introducing a manually or automatically collected sample that is representative of the manufactured product back into the one or more process analyzers. The results obtained for the representative sample from the on-line process analyzers are then used to represent the quality of the manufactured batch of petroleum material to certify that the manufactured batch meets regulatory, specification and/or contractual requirements.

  • Patent number: 8019617
    Abstract: A computer modeling application is disclosed for finding the optimal solution to maximize total net margin, for the assignment of vehicles (e.g., especially vessels) in an available fleet to perform a set of voyages to transport cargo comprising one or more bulk products during a planning period, as well as an apparatus and method employing the same. The fleet can include term vehicles and spot vehicles. The vehicles, voyages, and cargos can be heterogeneous. In one embodiment, the vehicles are crude carrier vessels and the bulk products are different grades of crude oil. To increase speed, the model is broken into linear programming and mixed integer (linear) programming problems. The model can be run on a real-time basis to support complex scheduling operations.

  • Patent number: 7491313
    Abstract: A method is disclosed for hydroprocessing a heavy hydrocarbon oil, comprising a first hydroprocessing step of bringing a heavy hydrocarbon oil into contact with a Catalyst (1) with a certain specific surface area and pore size distribution in the presence of hydrogen in a first reaction zone containing the Catalyst (1), and a second hydroprocessing step of bringing the hydroprocessed oil obtained from the first reaction zone into contact with a Catalyst (2) with a certain specific surface area and pore size distribution in the presence of hydrogen in a second reaction zone containing the Catalyst (2). The method is an improvement in decreasing or inhibiting the sediment formation, while highly hydroprocessing a heavy hydrocarbon oil containing a large amount of impurities such as sulfur, micro carbon residue (MCR), metals, nitrogen and asphaltene, especially a heavy oil containing a large amount of heavy vacuum residue, to adequately remove the impurities.

  • Patent number: 7389186
    Abstract: The invention provides a method and means of predicting, in near real-time, the detailed chemical composition of major streams in a refinery, including those downstream from the crude distillation column. The dynamically updated feed characterizations can be derived in near real time from an assay database of current crude diet, RTO information about upstream refinery units and various analyzer inputs. The chemical compositions of each stream are stored and updated in a plant wide database. A broad range of property calculations can be ascertained, either automatically or on demand, from the compositional information. An application permits users, such as operations, planning and engineering personnel, to access the database directly or indirectly (e.g., on line). This information is then used by each user to further optimize the operation of a given refinery unit and/or the plant as a whole.

  • Patent number: 7374665
    Abstract: A method of blending delayed coker feedstocks to produce a coke that is easier to remove from a coker drum. A first feedstock is selected having less than about 250 wppm dispersed metals content and greater than about 5.24 API gravity. A second delayed coker feedstock is blended with said first resid feedstock so that the total dispersed metals content of the blend will be greater than about 250 wppm and the API gravity will be less than about 5.24.

  • Patent number: 7096002
    Abstract: A navigation unit on board a mode of transportation is coupled to a communication device for transmitting an emergency call to a remote tracking center when an emergency button on the mode of transportation is depressed. The communication device is not audible or visible at the mode of transportation. Additionally the communication device is capable of being activated from a remote tracking center.
