Description
lysen icke omsatt "*"enen@ Till grund för uppfinningen ligger up giften att tillhandahålla ett förfarande där nan arbetar med en överdosering av ammoniak för att bortföra HOX och avlägsna ammoniaköverskottet u de kvarblivande av- gaserna utan extra kostnad, Uppgiften löses genom att avgaserna tillsammans med förfarandets hela annoniaxtillsats först tillförs till ett första processteg, som avlägsnar HDX, och som är av ett s'ag, där ett överskott av ammoniak utöver förbrukningen i prooessteget leder till ökad reaktionshastighet i proeessteget, och att avgaserna efter behandlingen i det första prooessteget tillförs tillsammans ned icke förbrukad ammoniak till ett andra prooessteg, som i närvaro av ammoniak avlägsnar svaveloxider, varvid nämnda hela ammoniaktillsats sätts att motsvara den totala förbrukningen i båda prooesstegene Föreliggande uppfinning grundar sig följaktligen på idén att man kombinerar ett godtyckligt med NH; arbetande förfarande för att avlägsna HDX med ett förfarande för rökgasavsvavling - exempelvis enligt den tyska patentskriften 24 31 130. Detta förut kända avsvav- lingsförfarande arbetar medelst tillsats av gasformig ammoniak, varvid ænnoniunsulfat framställes ur svaveloxiderna. Enligt uppfinningen till- sattes den härför erforderliga sanmoniakmängden på ett ställe - sett i gasströmmens riktning - vilket ligger före påbörjandet av NOx-förfaran- deto Den för KO:-borttagningen erforderliga ammoniakmängden höjes följ- ektligen enligt uppfinningen till det belopp som behövs för reaktionen med i rökgasen förhandenvarande SOX under den efterföljande avsvav- lingenq Därigenom ernås de ovan angivna fördelarna beträffande jäm- viktsinställningenø För NOK-borttagningen kan vilket som helst förfarande användas där man arbetar ned ammoniak och där vid processens slut jämviktstill- ståndet mellan ammoniak och H03 (resp andra komponenter) påverkar bort- tagningsgraden av HDX; då är nämligen ett ammoniaköverskott till fördel eftersom det leder till en avsevärd höjning av reaktionshastigheten. ärigenom ernås lägre investeringskostnader resp mindre omfattande anpar tur, eller vid samma storlek på anparaturen en högre grad av NOK-avlägsnandec För ett avlägsne,FOï kan man använda katalytiska re- duktionsförfaranden, eller adsorptions= och absorptionsprocesser, för- utsatt att dessa arbetar med ammoniaktillsats. lysen not sold "*" enen @ The invention is based on the information provided a process in which nan works with an overdose of ammonia to remove the HOX and remove the excess ammonia from the remaining the gases at no extra cost, The task is solved by the exhaust gases together with the procedure the whole anonyx additive is first added to a first process step, which removes HDX, and which is of a s'ag, where an excess of ammonia in addition to the consumption in the prooes step leads to increased reaction rate in the proees stage, and that the exhaust gases after the treatment in the first the prooes step is added together with unused ammonia to a second process step, which in the presence of ammonia removes sulfur oxides, wherein said whole ammonia additive is set to correspond to the total consumption in both prooesstegene Accordingly, the present invention is based on the idea that one combines an arbitrary with NH; working procedure to remove HDX with a flue gas desulphurisation procedure - for example according to German Patent Specification 24 31 130. This previously known desulphurisation The process works by adding gaseous ammonia, wherein Annonium sulphate is prepared from the sulfur oxides. According to the invention the amount of ammonia required for this was placed in one place - seen in direction of the gas flow - which is before the start of the NOx The amount of ammonia required for KO removal is increased accordingly. according to the invention to the amount needed for the reaction with SOX present in the flue gas during the subsequent desulphurisation This achieves the above advantages in terms of weight settingø For NOK removal, any procedure can be used where ammonia is worked down and where at the end of the process equilibrium the position between ammonia and H03 (respectively other components) affects the the degree of capture of HDX; then an excess of ammonia is advantageous as it leads to a significant increase in the reaction rate. thereby achieving lower investment costs or less extensive ones anpar luck, or at the same size of the anparatur a higher degree of NOK removal For a distance, FOï, one can use catalytic production processes, or adsorption = and absorption processes, exposed that these work with ammonia additive.
Kombinationen enligt unpfinningen har fördelen att graden NOX- borttagning påverkas fördelaktigt utan att otillåtligt höga mängderThe combination according to the invention has the advantage that the degree of NOX removal is favorably affected without excessively high amounts
