Abstract: A hydroprocessing method and system involves introducing heavy oil and well-dispersed metal sulfide catalyst particles, or a catalyst precursor capable of forming the well-dispersed metal sulfide catalyst particles in situ within the heavy oil, into a hydroprocessing reactor. The well-dispersed or in situ metal sulfide catalyst particles are formed by 1) premixing a catalyst precursor with a hydrocarbon diluent to form a precursor mixture, 2) mixing the precursor mixture with heavy oil to form a conditioned feedstock, and 3) heating the conditioned feedstock to decompose the catalyst precursor and cause or allow metal from the precursor to react with sulfur in the heavy oil to form the well-dispersed or in situ metal sulfide catalyst particles. The well-dispersed or in situ metal sulfide catalyst particles catalyze beneficial upgrading reactions between the heavy oil and hydrogen and eliminates or reduces formation of coke precursors and sediment.

Abstract: A method and apparatus to provide hop-by-hop tracking for a communication network is described. In one embodiment, a router verifies that a next downstream router supports tracking and in response, adds a tracking indicator and a timestamp to the data packet. An end router provides a compilation of all the timestamps back to the originating router.

Abstract: In an embodiment, an apparatus includes a housing and a cover. The housing can include a surface to receive a terminal block to transmit power to an electrical component. A shroud to be inserted within the electrical component can extend away from the housing surface. The cover can have an end for hingedly attaching to the housing. The cover is pivotable relative to the housing between a closed position and an open position. In the closed position, the cover and the housing together form an enclosure for the terminal block.

Abstract: A hydrocracking system is upgraded by modifying an existing ebullated bed initially utilizing a supported ebullated bed catalyst to thereafter utilize a dual catalyst system that includes metal sulfide catalyst particles and supported ebullated bed catalyst. The upgraded hydrocracking system achieves at least one of: (1) hydroprocess lower quality heavy oil; (2) increase conversion of higher boiling hydrocarbons that boil at 524° C. (975° F.) or higher; (3) reduce the concentration of supported ebullated bed catalyst required to operate an ebullated bed reactor at a given conversion level; and/or (4) proportionally convert the asphaltene fraction in heavy oil at the same conversion level as the heavy oil as a whole. The metal sulfide catalyst may include colloidal or molecular catalyst particles less than 1 micron in size and formed in situ within the heavy oil using a catalyst precursor well-mixed within the heavy oil and decomposed to form catalyst particles.

Abstract: A motor assembly for a direct current (DC) electric motor, including: a motor cover, a brush base, brush arms and a chip capacitor housed within a protective hollow space provided in the brush base. The brush arms are shaped to support or hold the capacitor within the hollow space and maintain a solderless electrical connection between the terminal ends of the capacitor and the brush arms. The capacitor filters electromagnetic noises in the motor input circuit.

Abstract: An apparatus includes a housing and a cover. The housing can include a surface to receive a terminal block to transmit power to an electrical component. A shroud to be inserted within the electrical component can extend away from the housing surface. The cover can have an end for hingedly attaching to the housing. Another cover end can be configured to releasably lock to the housing. The housing and the cover can have notches. The cover is pivotable relative to the housing between a closed position and an open position. In the closed position, the cover and the housing together form an enclosure for the terminal block, and the notches of the housing and the cover cooperatively define passageways configured to receive external wires to connect to the terminal block.

Abstract: A parallel optical communications module is equipped with an EMI waveguide (WG) device having a tube-like structure that surrounds portions of one or more optical fiber ribbon cables that pass through the tube-like structure and connect to the module. The EMI WG device attenuates EMI to acceptable levels to provide the module with effective EMI shielding capability.

Abstract: A hydrocracking system involves introducing a heavy oil feedstock and a colloidal or molecular catalyst, or a catalyst precursor capable of forming the colloidal or molecular catalyst, into a hydrocracking reactor. The colloidal or molecular catalyst is formed in situ within the heavy oil feedstock by 1) premixing the catalyst precursor with a hydrocarbon diluents to form a catalyst precursor mixture, 2) mixing the catalyst precursor mixture with the heavy oil feedstock, and 3) raising the temperature of the feedstock to above the decomposition temperature of the catalyst precursor to form the colloidal or molecular catalyst. The colloidal or molecular catalyst catalyzes upgrading reactions between the heavy oil feedstock and hydrogen and eliminates or reduces formation of coke precursors and sediment.

Abstract: A hydrocracking system involves introducing a heavy oil feedstock and a colloidal or molecular catalyst, or a precursor composition capable of forming the colloidal or molecular catalyst, into a hydrocracking reactor. The colloidal or molecular catalyst is formed in situ within the heavy oil feedstock by intimately mixing a catalyst precursor composition into a heavy oil feedstock and raising the temperature of the feedstock to above the decomposition temperature of the precursor composition to form the colloidal or molecular catalyst. The colloidal or molecular catalyst catalyzes upgrading reactions between the heavy oil feedstock and hydrogen and eliminates or reduces formation of coke precursors and sediment. At least a portion of a resid fraction containing residual colloidal or molecular catalyst is recycled back into the hydrocracking reactor to further upgrade the recycled resid fraction portion and provide recycled colloidal or molecular catalyst within the hydrocracking reactor.

Abstract: Risk Analytics Management—Integrated Process (“RAM-IP”), a computerized method for project optimization, process control and performance management based on a risk management framework. A project comprises a plurality of risk sources, e.g., nine, that are managed from Day One by establishing a plurality of risk streams, e.g., 32, that break down the risk at each source. Each risk stream is divided into a plurality of risk control steps, each of which is assigned a risk owner who works with various information inputs to manage a set of control deliverables and to control risk at each source. The project timeline is based on a sequence of critical milestones connected to completion of such control steps, all based on risk assessment and control. Technical, financial and process governance are process integrated. In a complex project, there may be thousands of control deliverables, requiring a software basis for continuous tracking, coordination, and updating.

Abstract: An ebullated bed hydroprocessing system, and also a method for upgrading an existing ebullated bed hydroprocessing system, involves introducing a colloidal or molecular catalyst, or a catalyst precursor capable of forming the colloidal or molecular catalyst, into an ebullated bed reactor. The colloidal or molecular catalyst is formed by intimately mixing a catalyst precursor into a heavy oil feedstock and raising the temperature of the feedstock to above the decomposition temperature of the catalyst precursor to form the colloidal or molecular catalyst in situ. The improved ebullated bed hydroprocessing system includes at least one ebullated bed reactor that employs both a porous supported catalyst and the colloidal or molecular catalyst to catalyze hydroprocessing reactions involving the feedstock and hydrogen. The colloidal or molecular catalyst provides catalyst in what would otherwise constitute catalyst free zones within the ebullated bed hydroprocessing system.
