  • Patent number: 7875103
    Abstract: Systems and related methods for separating liquids and particulate from a flowing gas stream include a separation vessel containing a liquid injector, an impingement separator or a helical impingement separator, and a waste liquid recovery tank. Separated liquid and particulate collect in a sump, flow into a recovery tank, and may be filtered in a side stream duplex filter circuit for return into the recovery tank and re-injection into the separation vessel. The helical separator element has outwardly extending helical fins that form helical gas channels. The interior of the channels forms a rounded radius and opposing vertical edges of the channels include chamfers. The lower end of the helical separator element forms a concave, generally conical surface. The helical fins form a first impingement separator and the chamfers form a second vane-type impingement separator, such that particulate and liquids may be removed from the gas stream at varying flow rates and liquid/particulate densities.

  • Patent number: 7682425
    Abstract: The invention relates to a method for removing ammonia and dust from a waste gas that occurs during the production of fertilizers, preferably urea, in which method the waste gas is introduced into a first washer, and a cooling gas is introduced into the one washer and an aqueous solution is introduced into the other washer, whereby both the waste gas and the cooling gas pass through at least one mist collector before exiting from the washer, in each instance, is supposed to be developed further in such a manner that the waste gas pollution can be clearly reduced. This is accomplished in that the additional water is first introduced into a fine-washing area of the first washer, delimited by the mist collector on the top and by a liquid-impermeable partition bottom at the bottom, and sprayed onto the at least one mist collector, and the aqueous solution that forms in the fine-washing area is subsequently passed into the second washer.
