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 multi-function electronic device is designed to provide a wide variety of functions. The device consists of two panels attached for relative movement by a hinge. The hinge provides a range of movement of a full 360°. The various functions are accessed by moving the relative position of the panels from 0°, to 165°, to 180°, to 300°, to 360°. Particular functions are correlated to panel orientations which ergonomically suit the selected functions.

Abstract: The ability of activated carbon to remove mercury and noxious polyorganic matter, especially chlorodibenzo-dioxins and -furans from incinerator flue gases is utilized in an efficient manner by suspending powdery activated carbon in the flue gas in connection with a conventional spray absorption process in which the acidic components of the flue gas are neutralized by means of basic absorbents. The cooling of the flue gases in the spray absorption process provides an efficient adsorption onto the powdery activated carbon and the separation of said powdery activated carbon from the flue gas is substantially facilitated by the presence of the particulate material formed by the spray absorption process. Also an improved removal of nitrogen oxides is obtained.
