Embodiments provide a particle production apparatus enabling the production of particles having an intended particle size and a narrow particle size distribution. A particle production apparatus includes a rotary disk and a material supply portion. In the material supply portion, a gas supply port is configured to supply a gas formed outside a material supply port. The gas supplied from the gas supply port directs the material supplied from the material supply port in such a way that the material comes into contact with the surface of the cylindrical portion.

A method of production of a homogeneous powdered product from a starting product in a liquid state, the starting product having sugars as at least 60% of its total solids, the method comprising: in the absence of air; pressurizing the starting product to a pressure greater than 1 bar; injecting a gas into the starting product to form a mixture in which the starting product is substantially saturated by the gas; and degassing the mixture into a continuous stream of transport gas such that, on contact with the transport gas, water from the mixture evaporates to leave the homogeneous powdered product.

The present invention relates to a method of manufacturing spray-dried powders. During the process, a solvent is used. The process is done batchwise such that the emulsification mass ratio is low when removal of the solvent is started. Preferred solvents are isopropyl acetate and ethyl acetate. The invention also relates to a set-up to run the inventive process at industrial scale.

A system and method for removing impurities to reconstitute a NaCl stream to a saturated solution salt solution and remove any impurities such as sodium bisulfite (NaHSO.sub.3), sodium chlorate (NaClO.sub.3) and sodium iodide (NaI) to improve brine quality from an electrolytic cell is disclosed, including an evaporation system connected to the electrolytic cell, a brine treatment system connected to the evaporation system and the electrolytic cell. A waste treatment system is connected to the evaporation system. The evaporation system includes a set of evaporators that concentrates the brine. Sodium chloride is precipitated from the set of evaporators to the brine treatment system. Impurities are precipitated from the set of evaporators. The brine treatment system includes a hydrocyclone and a centrifuge that separates sodium chloride from water. The sodium chloride is mixed with water to create a concentrated and purified brine.

A waste water processing system includes an upflow contacting column having a flue gas input for receiving flue gas having a temperature of at least 500 degrees F., a waste water input, and a flue gas output. The waste water input is coupled to a fluid injector, e.g., atomizing nozzles, positioned in the throat of a Venturi portion of the upflow contacting column or in a sidewall of the throat of the Venturi portion of the upflow contacting column. The flue gas in the upflow contacting column has a high velocity, e.g., a gas velocity exceeding 65 fps in the throat of the Venturi portion of the upflow contacting column at a position where the fluid injector is located. Drying additives such as recycled ash, lime, and/or cement may be, and sometimes are, input into the upflow contacting column downstream of the waste water input.
