Bromine recovery method and system include: providing and mixing (i) solid waste containing bromine compounds and (ii) solid calcium hydroxide; heating the mixture in a chemical reducing (non-oxidizing) environment, thereby forming heated product consisting essentially of only solid calcium bromide (salt); and processing the heated product, to form bromine. Calcium bromide manufacturing method and system include: providing and mixing (i) solid waste containing bromine compounds and (ii) solid calcium hydroxide; heating the mixture in a chemical reducing (non-oxidizing) environment, thereby forming solid calcium bromide (salt).

A volatiles consuming eductor system for coated scrap metal furnaces with separate delacquering and melt chambers. Motive gas is forced through an inlet into a mixing chamber in a direction opposite a suction port, creating a Venturi that draws gases from the delaquering chamber through the mixing chamber. The motive gas and the drawn gases mix and are forced through a discharge port, ignited, and injected into the melt chamber to help heat the melt chamber. A computer monitors process conditions and controls a regulator that adjusts the motive gas flow in response to those conditions.

In order to eliminate liquid accumulation occurring between a gas-liquid mixing part and a vaporization part to stably perform liquid feeding to the vaporization part and vaporization in the vaporization part, a liquid material vaporization apparatus includes: a gas-liquid mixing part adapted to mix a liquid material and gas to produce a gas-liquid mixture; and a vaporization part adapted to heat the gas-liquid mixture to vaporize the liquid material. In addition, the gas-liquid mixing part has a gas-liquid mixture lead-out pipe for leading out the gas-liquid mixture, the vaporization part has a heating flow path HS for heating the gas-liquid mixture, and a lead-out port of the gas-liquid mixture lead-out pipe is arranged in the heating flow path HS.

Initial liquid containing fine bubbles is produced by mixing water and air (step S11). Fine bubbles have diameters of less than 1 m. The density of bubbles in the initial liquid is measured (step S13), and when the measured density is less than a target density (step S14), the initial liquid is heated and reduced in pressure so that the liquid is vaporized (step S15). As a volume of the liquid decreases, the density of fine bubbles increases, and high-density fine bubble-containing liquid is easily obtained. Alternatively, by increasing the density of fine bubbles in the initial liquid with using a filter that does not pass all fine bubbles, high-density fine bubble-containing liquid is easily acquired (step S15). When the density of bubbles in the initial liquid is greater than the target density, the initial liquid is diluted (step S16).

The invention relates to a method for preparing emulsions.

In order to create a new method for preparing emulsions, in which homogenous oil droplets as small as possible can be generated with an energy input as low as possible, it is proposed in the scope of the invention, that at least two liquid streams of liquids that cannot be intermixed with one another are pumped through separate openings with defined diameters, in order to achieve flow velocity of the liquid streams of more than 10 m/sec., and in that the liquid streams collide at a collision point in a space, wherein the resulting emulsion is discharged from the space through an outlet.

By the collision of the liquid streams with high flow velocities, in which a plate-shaped collision plate is formed in the collision point, a homogenous emulsion having an oil droplet size of less than 1 m is achieved due to the kinetic energy, which is accordingly very stable as well. No further energy input, such as shear forces, is required to that end.

A high volume microfluidic system for producing emulsions includes a fluid distribution network to produce uniformly sized emulsions and encapsulates.
