The present invention relates generally to the field of emission control equipment for boilers, heaters, kilns, or other flue gas-, or combustion gas-, generating devices (e.g., those located at power plants, processing plants, etc.) and, in particular to a new and useful method and apparatus for reducing and/or eliminating various liquid discharges from one or more emission control equipment devices (e.g., one or more wet flue gas desulfurization (WFGD) units). In another embodiment, the method and apparatus of the present invention is designed to reduce and/or eliminate the amount of liquid waste that is discharged from a WFGD unit by subjecting the WFGD liquid waste to one or more drying processes, one or more spray dryer (or spray dry) absorber processes, and/or one or more spray dryer (or spray dry) evaporation processes.

The present invention relates to a system for one pot solids recovery from solutions, slurries, emulsions, dispersions, gels, semisolids, and their like. Further the system can be used for controlled concentration of solutions, slurries, emulsions, dispersions, gels, semisolids, and their like to enable easy to operate cost effective energy efficient processes. The system is so constructed to enhance the contact between the liquid medium and the gaseous medium used in the process for effective heat transfer. The system can be used for controlled concentration and/or recovery of substantially dry solids in applications related to foods, nutraceuticals, natural products, pharmaceuticals, chemicals, etc.

The present invention relates to a method of manufacturing spray-dried powders. During the process, a solvent is used. The process is done in a continuous manner and 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.

The electrospray device comprises a sprayer comprising a sprayer body and nozzle, and a partition positioned vertically and coaxially with the sprayer. The sprayer body is provided with a swirl generator for generating a swirling air stream, and a power supply connected between the nozzle and the partition, to apply voltage to the nozzle and the partition. The electrospray device may be part of a fluidized bed apparatus comprising a product container, a lower plenum base, an air distribution plate resided therebetween. When the power supply applies voltage in opposite polarities to the nozzle and the partition, the fluidized bed apparatus is used for coating particles; and when the power supply applies voltage of the same, the fluidized bed apparatus is used for spray-drying a solution. The electrospray device uses an electromagnetic hydrodynamic method to improve the performance of the fluidized bed apparatus and optimize the process of product.

A spray drying process and apparatus for drying a spray dryable liquid composition to a spray dried powder is described, in which the spray dryable liquid composition contains no carrier. The spray dryable liquid composition is processed at a solids concentration not exceeding 80% by weight, based on total weight of the spray dryable liquid composition, being atomized to generate an atomized spray of liquid particles of the spray dryable liquid composition into a spray drying chamber, in which the atomized spray is contacted with a stream of drying fluid flowed at temperature not exceeding 100° C. into the spray drying chamber, to form the spray dried powder.
