Abstract:
It provides for processing a dehydrated and salty hydrocarbon feed having a solid salt dispersed in a hydrocarbon material by contacting the feed with an active agent under a first operating condition under which the active agent has an initial active agent solubility in the hydrocarbon material, and modulating operating conditions to provide a second operating condition under which the active agent has a secondary active agent solubility in the hydrocarbon material that is less than the initial active agent solubility so as to form a separable active agent phase, wherein the salt solubility in the active agent is substantially greater than the salt solubility in the hydrocarbon material under both the first and second operating conditions such that the salt dissolves in the active agent, allowing the separable active agent phase to separate from the hydrocarbon material depleted in the salt.
Abstract:
A pumpbox apparatus includes a reservoir volume having a first inlet for receiving a feedstock stream and a second inlet for receiving a water stream, the reservoir volume being in communication with a discharge outlet disposed to discharge accumulated liquid from the reservoir volume. The reservoir volume is operable to accumulate the feedstock stream and the water stream in the reservoir volume while withdrawing a discharge stream through the discharge outlet to cause a flow of liquid through the pumpbox. The first inlet defines a first flow velocity region between the first inlet and the second inlet and a second flow velocity region between the second inlet and the discharge outlet. The first flow velocity is lower than the second flow velocity to facilitate flotation of a low specific gravity portion of the feedstock through the first region toward an upper surface of the liquid accumulated in the reservoir volume.
Abstract:
An extraction system and process for extracting bitumen from a slurry containing bitumen, solids and water. The system comprises a cyclone separation facility for separating the slurry into a solids component stream and a bitumen froth stream with the bitumen froth stream including water and fine solids. The bitumen froth stream is then delivered to a froth concentration facility for separating the bitumen froth stream into a final bitumen enriched froth stream, and a water and fine solids stream. The final bitumen enriched froth stream is suitable for further processing. The system of the present invention is preferably mobile so that the cyclone extraction facility and the froth concentration facility can move with the mine face at an oil sands mining site, however, it is also contemplated that the system can be retrofitted to existing fixed treatment facilities to improve the operational efficiency of such fixed facilities.
Abstract:
A sizing roller screen apparatus and method for processing an ore feed that includes sized and oversize ore portions and is received at an inlet are disclosed. The apparatus includes a roller screen having a plurality of adjacent screening rollers with interstices therebetween for permitting passage of the sized ore portions, the adjacent screening rollers being rotatable to cause a first sized ore portion to pass through the interstices as while the ore feed is transported along the roller screen. The apparatus also includes a sizing roller disposed generally above an opposing one of the adjacent screening rollers, the sizing roller being rotatable to fragment at least some of the oversize ore portions passing between the sizing roller and the opposing screening roller to produce a second sized ore portion, the second sized ore portion being sized for passage between the interstices.
Abstract:
Oil-in-water fungicidal formulations are prepared having pigment dispersed therein, the pigment being stable within the oil-in-water emulsion as a result of the addition of suitable silicone surfactants and suitable emulsifiers. The formulations can be prepared either as a 2-pack formulation or as a single formulation. In the case of the single formulation polyethylene glycol is also added. In either case, the formulations show a synergistic effect through the addition of the pigment, the resulting formulations having an increased efficacy. Further, the formulations show a synergistic effect when mixed with conventional chemical fungicides, both being added in reduced amounts compared to recommended rates.
Abstract:
An apparatus, process and system for treating a hydrocarbon feedstock having a specific gravity differential between components of the feedstock is disclosed and includes a treatment vessel having an inlet for receiving the feedstock. A primary separation container may be located in the treatment vessel to accumulate feedstock to cause a low specific gravity portion of the feedstock to separate and rise to an upper surface of the accumulated feedstock. A secondary separation container may be located in the treatment vessel to receive the collected low specific gravity portion from the primary separation container, to accumulate the collected low specific gravity portion to cause hydrocarbon products to separate and rise to an upper surface of the accumulated low specific gravity portion of the feedstock, producing a hydrocarbon product stream at a product outlet. The operating pressure of the treatment vessel may be regulated to remain within a desired range.
Abstract:
A system for heating conveyors which extend outside a wash tunnel of a carwash utilizes concrete structural slabs with heating apparatus embedded in the slab near a top surface and supported adjacent the conveyor. The heating apparatus can be a hydronic system or an electric heating mat embedded in the slabs which prevents water on the slabs or the conveyor from freezing in low ambient temperature conditions.
Abstract:
A slurry apparatus for creating a slurry from oil sand ore has a frame and a slurry box supported by the frame. Water is mixed with the ore to form a slurry that is retained in the slurry box. The slurry apparatus may include a screen disposed at an angle relative to the horizontal over an open top of the slurry box and configured to permit sized ore to fall through the screen into the slurry box. The apparatus may include at least one crushing device cooperating with the screen to facilitate creating the slurry. A related method and system for creating a slurry may also be provided.
Abstract:
A pump has a pump barrel formed from a larger diameter section and a smaller diameter section. Each section has a biased piston moveable within the section and the pistons are connected together to form a variable volume chamber between the pistons. As the connected pistons move toward the larger diameter section, a volume of fluid is moved through an inlet valve into the variable volume chamber of increasing volume. When the pistons are moved toward the smaller diameter section, a differential volume of fluid is discharged from the variable volume chamber of decreasing volume through a discharge valve into a discharge conduit. The pistons are actuated to move within the pump barrel by application and release of pressure at a remote end of the discharge conduit.
Abstract:
A method and process line apparatus for processing a sized ore feed excavated from an ore deposit is disclosed. The method involves disposing a processing apparatus in a processing apparatus position relative to the ore deposit, and disposing a first mobile conveyor to receive a sized ore feed at a receiving location located along a length of the first mobile conveyor. The first mobile conveyor is operable to convey the sized ore from the receiving location to a discharge end of the first mobile conveyor. The method also involves disposing a second mobile conveyor to receive the sized ore from the discharge end of the first mobile conveyor at a transfer location along a length of the second mobile conveyor and to convey the sized ore from the transfer location to the processing apparatus. The first and second mobile conveyors are oriented at an operational angle between a length of the first mobile conveyor and a length of the second mobile conveyor. The method further involves moving at least one of the first and second mobile conveyors to vary at least one of the operational angle and the transfer location to permit successive portions of the ore deposit within operational reach of the receiving location to be received for conveying along the first and second mobile conveyors to the processing apparatus while the processing apparatus is located in the processing apparatus position.
