20110064635 | METHOD FOR REDUCING AEROSOL EMISSIONS IN A UREA GRANULATION PLANT - The invention relates to a process for the granulation of a concentrated urea solution whereas the granulation produces a urea granulate and a dust laden air, which is then fed into a dust scrubber which removes the coarser dust with a less concentrated urea solution and which releases a residual air comprising air with ammonia, carbon dioxide water and an aerosol comprising mainly ammonium isocyanate and a part of very fine urea sublimate, whereas the aerosol is then separated off and fed into a isomerisation unit which comprises a stripping where the ammonium isocyanate reacts with steam to form urea which is then redirected into the dust scrubber as a less concentrated urea solution, and the residual air is directed into an acidic scrubber which releases clean air into the atmosphere which finally leads to a recycling of the aerosol of ammonium isocyanate into urea. The invention also relates to a device for carrying out the related process. | 03-17-2011 |
20110229394 | UREA GRANULATION PROCESS WITH AN ACIDIC SCRUBBING SYSTEM AND THE SUBSEQUENT INTEGRATION OF AMMONIUM SALT INTO UREA GRANULES - A process for the granulation of urea with a scrubbing system includes several waste streams for removal of dust and ammonia from the off-gas of a urea granulation unit. A urea granulator, a granulator scrubber dust stage, a granulator scrubber acid stage, product coolers, a product cooler scrubber dust stage, an evaporation unit, and a condenser unit are included in the system. A first stream of fresh air is sent into the urea granulator, whereby dust- and ammonia-laden air is drawn off from the granulator and conveyed into a granulator scrubber dust stage, followed by a granulator scrubber acid stage and ammonia is scrubbed from that air by the generation of an ammonium salt. A second stream of fresh air is used for cooling the product drawn off from the urea granulator in product coolers. The cooling air is thus heated up and conveyed to a product cooler scrubber dust stage. The clean off-gas drawn off from the granulator scrubber acid stage, and the clean off-gas drawn off from the product cooler scrubber dust stage, are released into the atmosphere. The scrubbing system is a complete closed system, and totally decoupled from urea synthesis. The ammonium salt solution stream from the granulator scrubber acid stage, is fed into the product cooler scrubber dust stage, whereby the ammonia of the dust-laden air stream exiting the product coolers is removed, and the released liquor from the product cooler scrubber dust stage and the released liquor from the granulator scrubber dust stage is sent to the evaporation unit. The vapour stream from the evaporation unit, which contains ammonia is sent to the condenser unit, which releases a liquid process condensate which is sent into the granulator scrubber acid stage, and the concentrated liquid stream from the evaporation unit, containing urea and ammonium salt, and a urea melt from a synthesis unit are conveyed into the urea granulator, separately. Thereby the ammonium salt contained in the concentrated liquor stream is integrated into the granulated urea product. | 09-22-2011 |
20130319060 | METHOD FOR PRODUCING UREA FERTILIZER WITH LOW MOISTURE ABSORPTION TENDENCIES - A method for producing urea granules having low moisture absorption capacity, with a urea granulator, having a granule flow inlet side and oppositely a granule flow outlet side, forming an axis alongside which granules from a urea solution and a urea/ammonium salt-stream are formed, whereby the solution and the salt-stream are sprayed as a mixture or separately via a feed system unit via various nozzles into the granulator onto a seed material. In this process the highest amount of the salt-stream is sprayed into the granulator at the granule flow inlet side and the amount of the salt-stream is decreased alongside the axis of the granulator from the granule flow inlet side to the granule flow outlet side. | 12-05-2013 |

20150133689 | UREA GRANULATION PROCESS WITH SCRUBBING SYSTEM - Disclosed is a method for producing granular urea and reducing ammonia emissions in a gaseous waste stream of the urea granulation process. The method includes the steps of granulating urea and generating a gaseous waste stream from the granulation of the urea, first washing the waste stream in a first scrubber dust stage to remove dust form the gaseous waste stream, and then reacting the gaseous waste stream with formaldehyde in a formaldehyde stage to generate a hexamethylenetetramine and urea-formaldehyde liquid stream, and an ammonia-reduced off-gas stream. | 05-14-2015 |

20100020538 | REFLECTOR EMITTER - A reflector emitter includes a combination reflector having at least one elliptical concave mirror shaped as an ellipsoid of revolution section having first and second focal points disposed outside and inside of the ellipsoid of revolution section, respectively. The reflector emitter includes at least one light source at the second focal point. The ellipsoid of revolution section is formed as an ellipsoid of revolution that is cut between its center and the first focal point in a longitudinal section plane and in a cross-sectional plane. An aperture is provided above an other concave mirror having at least one focal point that coincides with the first focal point of the ellipsoid of revolution section. The other concave mirror is formed as a hollow body cut in a sectional plane through its focal point. This sectional plane and the longitudinal section plane of the ellipsoid of revolution section share a common plane of reference and the concave mirrors have opposing faces. | 01-28-2010 |
