The current invention concerns a method for increasing an iron content of a solution by converting low iron containing solutions into highly concentrated ferric chloride solutions by adding iron containing substances. The invention concerns also methods for transporting and storage of said highly concentrated ferric chloride solutions.

The present invention relates to a mixing apparatus. A production unit produces a working fluid that is in a supercritical state or a subcritical state. A storage unit stores a material. A dissolving unit dissolves the material in the working fluid. A mixer mixes the material together in the presence of the working fluid. A material feed valve opens or closes a flow passage through which the material is to pass to be fed from the storage unit into the dissolving unit. A working fluid inflow valve opens or closes a flow passage through which the working fluid is to pass to flow into the dissolving unit from the production unit. A mixer inflow valve opens or closes a flow passage through which the working fluid and the material are to pass to flow into the mixer from the dissolving unit.

A device for generating bubbles or droplets may include a cavity comprising a first pressurized phase, at least one input capillary of a second phase, and an output capillary coaxially aligned with the at least one input capillary. The opening of the tip of the at least one input capillary has an internal diameter of less than half the internal diameter of the output capillary. The cross section of the cavity may be selected so that, in use, the average speed field in the cavity is quasi-static.

A method of forming microcapsules having improved physical properties and release control as well as the microcapsules formed by the process wherein the capsule wall is formed by the concurrent polymerization of monomers, oligomer and/or prepolymers on the inside of the capsule wall and different monomers, oligomers and/or prepolymers on the exterior of the capsule wall as it forms.

The invention relates to a method and a colloidal mixer for colloidal processing of a slurry, in particular processing of construction materials, with a colloidal mixer, in which at least one liquid is introduced into a mixing trough, at the lower region of which is arranged an outlet opening with a mixing device having a mixing rotor, which is driven in rotation.

According to the invention, the at least one pulverulent solid component is introduced into the mixing trough, the at least one liquid mixed with the at least one pulverulent solid component is induced to flow by the rotatingly driven mixing rotor and is discharged from the mixing trough through the outlet opening, wherein the mixture is led back again for a certain time via a backflow line into an upper region of the mixing trough for further mixing and, after a desired mixing state has been attained, the mixture is discharged as a finished slurry from the outlet opening by means of a discharge line.

According to the invention, it is provided that air is incorporated into the at least one liquid and/or the mixture in a targeted manner in a finely dispersed form, wherein a relative density of the liquid, or of the mixture, is reduced.

Provided is a method for preparing an oligomer including: supplying a monomer stream and a solvent stream to a reactor to perform an oligomerization reaction to prepare a reaction product; supplying a discharge stream from the reactor including the reaction product to a separation device and supplying a lower discharge stream from the separation device to a settling tank; adding an organic flocculant to the settling tank to settle and remove a polymer and supplying the lower discharge stream from the separation device from which the polymer is removed to a high boiling point separation column; and removing a high boiling point material from the lower portion in the high boiling point separation column and supplying an upper discharge stream including an oligomer to a solvent separation column.

According to some embodiments, a system and method for dispensing a floor coating in a specified ratio of multiple components is disclosed. The system and method may set and maintain a desired ratio of the multiple components by controlling, with a controller, a drive rate of respective pumps configured for propelling the components from a reservoir to a mixer or a dispenser. The controller may be responsive to at least one of a measured actual drive rate, an environmental condition, an actual usage of each component, and an operational parameter of the system, for adjusting a drive rate of the respective pumps to compensate for discrepancies that may affect the ratio of the multiple components.
