A device and method for dispersing oil on water comprises a rig structure for being mounted in a vessel, the rig structure including a front transverse structure with at least one nozzle for flushing with pressurized water supplied from a pressure facility located on the vessel.

In one example, a liquid mixture nozzle for flowing a liquid mixture therethrough includes a body having a flow inlet and a flow outlet. The flow inlet is configured to couple to a first piece of piping and the flow outlet is configured to couple to a second piece of piping. The liquid mixture nozzle also includes a converging section having a decreasing diameter positioned adjacent the flow inlet, an orifice positioned at a narrow end of the converging section, an intermediate section having a constant diameter positioned adjacent the orifice, a diverging section having an increasing diameter positioned adjacent the intermediate section and the flow outlet.

A tank cleaning machine comprising a housing having an inlet and a stationary guide diverter disposed within the housing. A gearing mechanism is attached to the stationery flow diverter. A nozzle extends from the housing wherein the nozzle is in fluid communication with the inlet and the nozzle includes an inclined portion extending from a horizontal portion of the nozzle. A drag limiter extends into a hydraulic fluid reservoir to limit the rotation speed of the gear.

A system for increasing useful energy output includes a source of hot combustion gas, such as from a gas turbine engine, and an apparatus that is disposed downstream of and receives the hot combustion gas and acts thereon to optimize electricity/thrust energy output of the system. The apparatus includes a housing that is coupled to the source and receives the hot combustion gas and also includes a rotatable shaft centrally disposed within the housing. A rotatable fluid moving device is coupled to the rotatable shaft and is configured such that the rotatable fluid moving device moves the hot combustion gas into a shape within the housing such that useful energy output/thrust is increased. Optionally, the system includes a spray nozzle that discharges water droplets upstream of the rotatable fluid moving device in a high temperature environment such that the action of the rotatable fluid moving device generates water vapor (steam) having a particular profile (e.g., annular shaped).

A cavitation device and method for using the same is useful for cavitationally treating fluids by generation of hydrodynamic cavitation in the fluid followed by the subsequent collapse of cavitation bubbles. The passage of fluid through slot openings in a cylindrical insert mounted in a housing provides fluid jets in an annular cavity to induce hydrodynamic cavitation of the fluid. Fluid is discharged from the annular cavity into a downstream portion of the housing to collapse cavitation bubbles under static pressure.

An exhaust system for a diesel engine, includes an exhaust passage adapted to be attached to the diesel engine. A diesel oxidation catalyst is provided in the exhaust passage along with a selective catalyst reduction device disposed downstream from the diesel oxidation catalyst. A diesel exhaust fluid mixing system includes a diesel exhaust fluid injection nozzle and a mixing device defining a single inlet opening and a single outlet opening connected to one another by a partial spiral flow passage. The diesel exhaust fluid injection nozzle injects diesel exhaust fluid directly into the inlet opening of the partial spiral flow passage.

A burner includes a first tube portion formed with an ejection port; a second tube portion that extends in the first tube portion toward the ejection port and to which gaseous mixture flows in from a side opposite to the ejection port; a third tube portion arranged in the first tube portion and including an open end positioned on the ejection port side; a closing portion that closes the open end; a coupling wall portion that closes a gap between the first tube portion and the second tube portion; a partition wall that is coupled to the first tube portion and the third tube portion, the partition wall being formed with a communication path; and an igniting portion that is arranged on the ejection port side with respect to the partition wall.

Disclosed herein are a method for producing a miniaturized liposome on a large production scale, and an apparatus for producing a liposome which is to be used in the above-mentioned method. Provided is a method for producing a liposome, including a step of stirring a mixture containing an oil phase in which at least one lipid is dissolved in an organic solvent and a water phase in a first tank of an apparatus having the first tank and a circulation path, in which the ratio of the capacity of the circulation path to the total capacity of the tank and the circulation path is 0.4 or less and/or the time required for the mixture to return to the first tank after being discharged therefrom is within 2.0 minutes.

Method of homogenizing a liquid, in particular a colorant for paint, in a container, comprising the steps of withdrawing liquid from the container at a first flow speed (S1) and then returning the liquid to the container at a second flow speed (S2), higher than the first flow speed (S1).

Hydrocarbon-containing feedstocks are processed to produce useful intermediates or products, such as fuels. For example, systems are described that can process a petroleum-containing feedstock, such as oil sands, oil shale, tar sands, and other naturally-occurring and synthetic materials that include both hydrocarbon components and solid matter, to obtain a useful intermediate or product.
