Abstract:
The subject of the invention is a flow disperser for mixing substances, in particular for breaking up, dissolving and emulsifying liquids and/or powders. A flow disperser comprising a casing equipped with a perforated inner stator and a rotating drive shaft with a fixed impeller according to the invention is characteristic in that the impeller (4) with the swirling baffle (5) divides the mixing area into two mixing chambers (6) and (7), wherein the inlet port of the mixture ingredients (8) for the mixing chamber (6) is located in the axis of the casing (1) with the fixed impeller (4) and the outlet (9) of the product is made in the side surface of the casing (1) in the mixing chamber (7).
Abstract:
An inline mixer that can monitor and adjust its output torque and speed in real time to adjust mixing properties to suit changing fluids flowing therethrough. In one embodiment, structures can be constructed to provide different mixing characteristics via different shapes, configurations, and spacing, which can be formed therein and such structures can optionally be replaced to further customize mixing properties.
Abstract:
It is an object to provide a method for producing compound semiconductor particles in which monodisperse compound semiconductor particles can be prepared according to the intended object, clogging with products does not occur due to self-dischargeability, a large pressure is not necessary, and productivity is high. In producing compound semiconductor particles by separating and precipitating, in a fluid, semiconductor raw materials, the fluid is formed into a thin film fluid between two processing surfaces arranged so as to be able to approach to and separate from each other, at least one of which rotates relative to the other, and the semiconductor raw materials are separated and precipitated in the thin film fluid. Further, in producing semiconductor microparticles containing semiconductor elements by reacting a compound containing semiconductor elements, in a fluid, with a reducing agent, the fluid is formed into a thin film fluid between two processing surfaces arranged so as to be able to approach to and separate from each other, at least one of which rotates relative to the other, and the compound containing semiconductor elements is reacted with the reducing agent in the thin film fluid.
Abstract:
A reactor is provided for the preparation of modified bitumen, which reactor comprises a horizontal housing comprising a cylindrical wall and two side walls, wherein a bitumen inlet has been provided at or near one of the side walls of the housing and a bitumen product outlet has been provided at or near the opposite side wall of the housing, wherein a plurality of inlets for the provision of oxygen-containing gas has been provided in the cylindrical wall of the housing between the bitumen inlet and the bitumen product outlet, which multi-purpose reactor is further provided with a mixer arranged inside the housing comprising at least one rotor rotating within at least one stator having a plurality of openings. Also there is provided a process for the preparation of modified bitumen, which comprises contacting bitumen at elevated temperature and pressure with a modifier in a reactor as herein described.
Abstract:
Mixing apparatus and methods for the continuous production of monomer emulsions that may be used in the production of polymer dispersions by radical aqueous emulsion polymerization. The mixing apparatus can include a pipe-in-pipe injector (100) and a suitable rotor-stator mixer (102). Liquids are delivered to the rotor-stator mixer via an inner (110) and an outer (108) pipe in such a way as to substantially prevent feed inconsistencies in a feed ratio of the liquids prior to entering a mixing zone of the rotor-stator mixer for emulsion formation.

Abstract:
A combined tangential shear homogenizing and flashing apparatus for destructuring pretreated biomass comprises a housing connectable to a source of pressurized pretreated biomass, and a stator and a rotor mounted within the housing. The stator and rotor being confrontationally disposed and spaced apart by a non-uniformly dimensioned axial gap. The least axial dimension between the rotor and the stator defining a restriction to a biomass flow. In use, rotational movement of the rotor with respect to the stator imparts a tangential shear to a volume of pretreated biomass. The tangential shear homogenizes the volume of pretreated biomass while a pressure difference causes a partial phase separation of the homogenized biomass into vapor and liquid phases such that the pretreated biomass undergoes at least a three-fold total volumetric increase and a weight transition to a vapor of at least one percent (1%).
Abstract:
A fluid processing method includes extraction that can extract material to be extracted continuously with high efficiency. A thin film fluid is formed between at least two processing surfaces disposed facing each other so as to be able to approach to and separate from each other such that at least one rotates relative to the other. A fluid processing extracts at least one kind of material to be extracted in at least one kind of the extraction solvent that can extract that material to be extracted. The fluid containing material to be extracted and a fluid for extraction that contains the extraction solvent are mixed in the thin film fluid formed between the processing surfaces, and a fluid processing process extracts the material to be extracted into the extraction solvent.
Abstract:
System and method provide a rapid mobilization and deployment technique for effectively mechanically dispersing marine oil spills that either eliminates or reduces the use of chemical dispersants. The disclosed systems and methods work by mechanically generating finely dispersed oil and gas droplets which may improve the dispersion of the hydrocarbons into the water column which can increase the rate of natural degradation of hydrocarbons in the water column.
