The present invention relates to an apparatus for producing a fuel made by mixing water with oil in a vacuum state. The apparatus includes: a vacuum tank adapted to seal an internal space thereof to allow the internal space to be maintained to a vacuum state; a vacuum pump located on one side of the vacuum tank to suck the air from the interior of the vacuum tank, so that the vacuum tank is kept in the vacuum state; a stirring vessel located inside the vacuum tank in such a manner as to communicate with the vacuum tank through a bypass pipe, the water and oil being supplied thereto; and stirrers rotating by the drive of motors to stirringly mix the water with the oil.

The present invention is directed to a special device for fast mixing and precipitation reactions of chemical substances. In particular, the present invention presents a reactor which allows an extremely fast mixing of at least two liquid streams containing highly concentrated dissolved materials from which solid metal compound particles are formed when at least two reactant streams meet, to which optionally a further stream, advantageously containing a dispersion or suspension, may be added.

The present invention provides a method and system for providing on-site electrical power to a fracturing operation, and an electrically powered fracturing system. Natural gas can be used to drive a turbine generator in the production of electrical power. A scalable, electrically powered fracturing fleet is provided to pump fluids for the fracturing operation, obviating the need for a constant supply of diesel fuel to the site and reducing the site footprint and infrastructure required for the fracturing operation, when compared with conventional systems.

Provided is an ultrafine bubble generation device for aquaculture or wastewater treatment with which it is possible to efficiently cause ultrafine bubbles to be dissolved or to coexist, and to increase the concentration of a gas in the liquid. An ultrafine bubble generation device for aquaculture or wastewater treatment provided with a channel for channeling a liquid, a compression device for pumping a gas into the channel, and a bubble generation medium for releasing the gas pumped by the compression device as ultrafine bubbles into the liquid in the channel, wherein the bubble generation medium is formed from a carbon-based porous material and is disposed so as to be horizontal or below horizontal with respect to the direction of flow of the liquid in the channel.

A gas/liquid dissolution device includes: a dissolution case; an introduction port outside a side surface of the dissolution case; a gas/liquid separation inducing means in the dissolution case, the gas/liquid separation inducing means inducing the dissolution water and an insoluble gas introduced into the dissolution case; and a discharge port outside an end portion of the dissolution case. The introduction port includes: an introduction tube connected to the dissolution case; an insertion tube inserted into the introduction tube; and an intake tube connected to the insertion tube. The discharge port has a structure where a discharge flow path communicating with an interior of the dissolution case is formed therein. The gas/liquid separation inducing means includes: a first gas/liquid separation guide tube, one side end portion of the first gas/liquid separation guide tube contacting an end surface of a discharge portion of the dissolution case and an other side end portion of the first gas/liquid separation guide tube spaced apart from an opposite end surface of the dissolution case; and a second gas/liquid separation guide tube, one side end portion of the second gas/liquid separation guide tube spaced apart from the end surface of the discharge portion of the dissolution case and an other side end portion of the second gas/liquid separation guide tube contacting the opposite end surface of the dissolution case. A guide channel is formed on each of the first gas/liquid separation guide tube and the second gas/liquid separation guide tube, and the insoluble gas is separated from the dissolution water to flow by the guide channel. The different kinds of the soluble gases are easily introduced through the intake tube. As a result, the dissolution ability of the gas is improved and the separation ability of the insoluble gas is also improved. Therefore, the dissolution water including the microbubble is effectively generated, and a phenomenon that the flow state of the dissolution water is deteriorated by the insoluble gas is prevented.

A fuel air delivery circuit, system, and method for the intake of an internal combustion engine, that provides an enhanced pressure condition to a supplementary or auxiliary air fuel circuit or circuits in connection with a conventional fuel delivery passage or passages, such as, but not limited to, a main, needle, or other jet, injector port, manifold, plenum, or the like, to provide enhanced vaporization and mixture of the fuel and air, and delivery to an associated intake path, such as the bore of a carburetor, intake runner, or the like, to provide improved throttle response and acceleration, and additionally which supplementary circuit will automatically recharge with fuel when a triggering condition is present, such as under steady state and deceleration conditions.

Disclosed herein are apparatuses and methods for conducting multiple simultaneous micro-volume chemical and biochemical reactions in an array format. In one embodiment, the format comprises an array of microholes in a substrate. Besides serving as an ordered array of sample chambers allowing the performance of multiple parallel reactions, the arrays can be used for reagent storage and transfer, library display, reagent synthesis, assembly of multiple identical reactions, dilution and desalting. Use of the arrays facilitates optical analysis of reactions, and allows optical analysis to be conducted in real time. Included within the invention are kits comprising a microhole apparatus and a reaction component of the method(s) to be carried out in the apparatus.

An apparatus and method produce hydrogen water that has antioxidant functions and abundantly contains dissolved hydrogen. Water is purified and sterilized for producing hydrogen water by supplying hydrogen gas to the purified and sterilized water. The hydrogen water is packaged into a container. The hydrogen gas is injected into the container to a saturated state by blowing. Leakage of the hydrogen gas is blocked by sealing the container. Since the concentration of hydrogen is increased to a saturated state by hydrogen blowing, a high-concentration hydrogen water is provided, and the shelf life is extended to two years, thereby enabling distribution of the hydrogen water without problem at stores. The hydrogen water has an excellent antioxidant function and suppresses the accumulation of fine dusts in a body, unlike general water, prevents, improves and treats pneumoconiosis caused by accumulation of fine dusts in lungs, and allergies and inflammations caused by fine dusts.

A chemical reaction device that supplies a raw material liquid into a solution and causes particles to precipitate in the solution is provided. The chemical reaction device includes an agitation tank configured to accommodate the solution, an impeller configured to agitate the solution, and a plurality of discharge parts configured to discharge the raw material liquid into the solution.

An apparatus and a method for treating fluids with ultrasound are provided. In order to achieve a desired effect of the treatment as efficiently as possible, the apparatus has a plurality of inlet openings for the fluids and the fluids to be brought into contact with one another while being exposed to ultrasound.
