Abstract: In the application a spray dryer absorption apparatus for treating a stream of flue gas containing acidic components is disclosed. The apparatus comprises a chamber having vertical cylindrical walls, said chamber comprises (i) an inlet for a flue gas stream containing an acidic component, (ii) an atomizer for spraying droplets of an absorbent slurry into said flue gas stream to effect a chemical reaction between the droplets and the acidic component of the flue gas, thereby forming a particulate reaction product, and (iii) an outlet for the treated flue gas and entrained particulate reaction product, wherein the bottom of the chamber having vertical cylindrical walls is substantially horizontal and impervious to gases. The apparatus of the invention has the advantage of a simplified geometry accounting for lower building and maintenance costs.

Abstract: Disclosed herein is a method for reducing the amount of coarser particles from a stream of flue gas prior to treatment by a spray dryer absorption process (SDA). The method comprises the steps of directing a stream of flue gas containing entrained particles of varying sizes through a curve, thereby subjecting the particles to a centrifugal effect, collecting the particles predominately of the coarser size at a particles collecting means provided in the outer circumference of the curve, dispersing the flue gas reduced in particles of coarse particle sizes into the chamber of a spray dryer absorption apparatus, wherein the particles content of the original flue gas stream is above 20 g/Nm3. Also an apparatus for performing the method and a gas disperser is disclosed. The method substantially reduces the cost of the entire plant for treating flue gas having a high content of entrained coarse particles by eliminating the need for a particle pre-collector upstream the SDA.

Abstract: A combine harvester (10) comprising a pair of axial separating rotors (20) each extending side-by-side within respective housings (19) in a longitudinal direction and serving to separate grain from straw. A feed beater (18) is provided which rotates on a transverse axis (X) and is located in front of the separating rotors to direct a crop flow rearwardly under the feed beater. Directional vanes (34) on the feed beater direct the crop flow away from a central zone of the beater and toward respective crop streams associated with the two rotors. Scraper apparatus (50) comprising stationary vanes (54) are provided above the beater. Crop material which back feeds over the top of the beater is scraped free of the beater and directed outwardly by the stationary vanes so that the scraped material is re-fed under the beater away from the central zone.

Abstract: Techniques for distributed workflow processing are presented. A first workflow system and a second workflow system process actions of a workflow. The workflow is coordinated through one or more identity services. The identity services also establish trusted and secure communications between the first and second workflow systems.

Abstract: A method and a device for detecting flash gas in a vapour-compression refrigeration or heat pump system comprising a compressor, a condenser, an expansion device, and an evaporator interconnected by conduits providing a flow path for a refrigerant, by determining a first rate of heat flow of a heat exchange fluid flow across a heat exchanger of the system and a second rate of heat flow of the refrigerant across the heat exchanger, and using the rates of heat flow for establishing an energy balance from which a parameter for monitoring the refrigerant flow is derived, to thereby provide early detection of flash gas with a minimum number of false alarms.

Abstract: A desulphurization process, in which acid components of waste gas are removed by spray drying absorption, using an aqueous suspension of slaked lime or limestone as absorbent with recycling of part of the reaction product to the absorbent, is controlled on the basis of determination of the chloride content of the aqueous suspension including recycled reaction product.
