Abstract: 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.

Abstract: Disclosed is a method for the re-compression of process generated steam to create a higher pressure steam that is useful as a heating medium in other parts of a carboxylic acid production process or, in general utilized in another process. The invention comprises the following basic steps: (a) recovering thermal energy from at least a portion of the high temperature process stream resulting from an aromatic carboxylic acid production process in a first heat transfer zone to produce a low pressure stream; (b) subjecting the low pressure steam to a compression zone to generate an intermediate pressure steam; (c) utilizing the intermediate pressure steam as a heating medium, specifically within other parts of the carboxylic acid process or generally in another process thereby generating steam condensate; and (d) optionally, recycling all or part of the steam condensate to the second heat transfer zone for low pressure steam generation.

Abstract: The fossil fuel fired continuous-flow steam generator has a gas turbine combustion chamber for fossil combustibles. On the heating gas side a vertical gas extractor is mounted downstream of a horizontal gas extractor. The walls surrounding the combustion chamber are composed of vertical evaporator tubes that are welded together. During operation the temperature differences between adjacent evaporator tubes of the combustion chamber are kept as low as possible. The burners are arranged at the level of the horizontal gas extractor.

Abstract: A blending chamber for blending fluids used to dry particulate matter has a chamber body with a first inlet opening, a second inlet opening, a third inlet opening, an outlet opening and a blending section. The blending section is arranged in a flow direction downstream of the first, second and third inlet openings, and upstream of the outlet opening. Fluids entering the first, second and third inlet openings are blended together in the blending section before exiting through the outlet opening. The bending chamber may be used to dry sawdust in a system that does not require a dedicated heat source.

Abstract: A method for operating a system for steam generation includes generating steam from water by indirect heat exchange with hot flue gas, by first preheating condensed water and then evaporating the preheated water at high pressure. The method further includes cooling the preheated water which is already at high pressure, by heat exchange with at least one partial flow of the condensed water, at least in a partial-load range. A system for steam generation, such as in a gas and steam turbine plant, includes a steam generator through which hot flue gas flows. The steam generator has heating surfaces. One of the heating surfaces is a condensate preheater having primary and secondary sides. A heat exchanger is connected downstream of the condensate preheater on the primary side and is connected upstream of the condensate preheater on the secondary side.

Abstract: In a steam generating system, steam condensate extracted from steam used to reheat boiler water in heaters (H1, . . . , H4) is revaporized in the recuperators-vaporizers (RV1, . . . , RV3) by heat exchange contact with the flue gas from boiler (B). The steam thus formed is recycled to contribute to the reheating of the water fed to the boiler.
