摘要： 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.

摘要： An aqueous sucrose solution is evaporated continuously while being subject to vigorous mechanical agitation to produce a sucrose suspension which is spray dried immediately, after which the spray dried product is post-crystallized and post-dried. A complete recovery is obtained of the sucrose present in the solution, in a process which is simple and economical since injection of sucrose crystals in the drying gas in the spray drier is omitted.

摘要： 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. The chloride content of the absorbent is used as the basis for (a) controlling the amount of chloride in the aqueous suspension to such a value that a specific chloride content of the spray dried product is between 1 and 7% by weight, and, within this range is related to the difference between the temperature of the desulphurized waste gas and the adiabatic saturation temperature thereof, and/or (b) for controlling the quantity of water evaporated by the spray drying, which is also related to the set forth chloride content, to change the difference between the temperature of the desulphurized waste gas and the adiabatic saturation temperature thereof, to provide a minimum temperature difference so as to maximize the acid base reaction yet maintain an actual temperature difference high enough to avoid sticky products.
