Systems and methods for dissolving ozone gas in a liquid. An embodiment can comprise a tank having an upper region, a lower region, and a discharge outlet, all disposed in a specified geometry. A pump can be coupled with a liquid inlet in order to receive a liquid therefrom and to deliver the liquid via a pipe to the upper region of the tank. The pump can be coupled with the lower region of the tank in order to receive the liquid from the tank and to recirculate the liquid to the upper region of the tank. The apparatus can include an ozone inlet to receive ozone into the tank. The ozone inlet can comprise a venturi inlet disposed on the pipe downstream of the pump. The liquid can be released from the tank and depressurized, thereby providing for the ozone to emerge from the liquid as gas bubbles. The released liquid can be selected for a two-stage gas and aqueous cleaning process.

The present application provides a method and a system for recycling a polymer. The method includes introducing polymer into a primary melting extruder, producing a polymer melt that is combined with a fluid oil to at least partially dissolve the polymer melt. A secondary mixing extruder mixes these to form a polymer solution that is introduced into a refinery oil stream, producing a polymer-comprising oil stream, which is fed into a refinery process unit. The system includes a primary melting extruder for forming a polymer melt from polymer. A secondary mixing extruder receives the polymer melt. One or more hydrocarbon inflow conduits for providing a fluid oil to the primary melting extruder and/or the secondary mixing extruder are configured to form a polymer solution from the fluid oil and the polymer melt. There is a feed system outlet for feeding the polymer solution to a refinery oil stream.

Parallel reactor systems for synthesizing materials are disclosed. The reactor systems may include at least two reaction vessels and may be suitable for synthesizing materials produced from corrosive reagents, for example, Ziegler-Natta catalysts. Antechambers may be provided above the reaction vessels to help purge vapors produced by the corrosive reagents. Methods for preparing materials by use of such parallel reactor systems are also disclosed.

A device and method for producing a bone cement paste from a monomer liquid and a cement powder, wherein the device comprises a cartridge with a cylindrical interior chamber for mixing the parent components, whereby the interior chamber of the cartridge is closed on the front side up to a delivery opening for expelling the bone cement paste from the interior chamber, a delivery plunger which is arranged in the interior chamber of the cartridge and which is supported in a linearly movable manner in the direction of the delivery opening, the cement powder, which is arranged in the interior chamber of the cartridge between the delivery opening and the delivery plunger, a monomer receptacle with an interior chamber in which a monomer liquid container containing the monomer liquid is contained, whereby in the monomer receptacle, a conveying plunger is arranged movable in the longitudinal direction of the monomer receptacle, a compressed gas connection, whereby the conveying plunger is arranged between the monomer liquid container and the compressed gas connection or the compressed gas line in the monomer receptacle.

There is provided an arrangement (100) which allows for mixing a first fluid with a second fluid at a predetermined volume mixing ratio in a capillary driven fluidic system. The arrangement (100) allows filling an initially empty mixing chamber (110) with the first fluid. The arrangement then allows emptying a predetermined fraction of the first fluid from the mixing chamber (110) such as to form an empty space in the mixing chamber (110). The arrangement then allows filling the empty space of the mixing chamber (110) with the second fluid, thereby allowing a predetermined volume of the first fluid to mix with a predetermined volume of the second fluid over time.

The invention discloses a low-energy consumption solvent dilution device for pre-treating samples comprising an accommodating unit, the accommodating unit including a case and an accommodating portion arranged inside the case; an input unit, which including an inlet, a second outlet and a third outlet extending into the case; a cleaning unit, which including a receiving assembly arranged below the second outlet and the third outlet, and a conveying assembly communicated with a receiving assembly. The input unit including a first tube connecting with the inlet, and a second tube and a third tube extending out of the second outlet and the third outlet, respectively.

The present invention completes dispensing and diluting the sample fixative in the box, the dispersion of the fixative is reduced. Avoid unnecessary contact for operators. It improves the safety and accuracy of the experiment, and significantly reduces energy consumption and labor costs.
