Description
Foreliggende oppfinnelse angår en anvendelse og en femgangsmåte for å oppnå i det vesentlige fullstendig oksidasjon av svoveldioksid oppløst i sjøvann til sulfat ved reaksjon med oksygen. The present invention relates to an application and a five-step method for achieving substantially complete oxidation of sulfur dioxide dissolved in seawater to sulphate by reaction with oxygen.
Artikkelen "The rate of sulfite oxidation in seawater" av Zhang og Millero, Miami Universitet, beskriver hvordan oksideringshastigheten av sulfitt i sjøvann varierer som funskjon av pH. The article "The rate of sulfite oxidation in seawater" by Zhang and Millero, University of Miami, describes how the oxidation rate of sulfite in seawater varies as a function of pH.
Flåkt-Hydro prosessen for avsvovling av avløpsgass (FGD) benytter sjøvann som et gjennomgangsabsorbsjonsmiddel. Sjøvann er i seg selv alkalisk med en pH på 8,0 til 8,3. Avløpsgass som inneholder svoveldioksid blir skrubbet i en absorber med sjøvann. Det absorberte svoveldioksid trenger å bli oksidert til sulfat før uttømming i sjøen for miljøgrunnet. Følgelig, blir svovel inneholdende vann overført til et luftebasseng i hvilket luft og fersk sjøvann blir tilsatt, og oksidering av oppløst svoveldioksid til sulfat blir utført. Luftebassenget kan enten være lokalisert på bunnen av absorberen, i kjølevannskanalen, i sammenkoplingsrør, eller som et separat anlegg. The Flåkt-Hydro process for waste gas desulphurisation (FGD) uses seawater as a pass-through absorbent. Seawater is inherently alkaline with a pH of 8.0 to 8.3. Waste gas containing sulfur dioxide is scrubbed in an absorber with seawater. The absorbed sulfur dioxide needs to be oxidized to sulphate before discharge into the sea for environmental reasons. Consequently, sulfur-containing water is transferred to an aeration basin to which air and fresh seawater are added, and oxidation of dissolved sulfur dioxide to sulfate is effected. The air pool can either be located at the bottom of the absorber, in the cooling water channel, in connecting pipes, or as a separate facility.
Mengden av oksidering er strengt temperaturavhengig, og spesielt for de steder med kaldt vann er oksideringen langsom. For å sikre fullstendig oksidering, må oppholdstiden og således luftebassengets volum være stort. Luftebassenget er en kostbar del av FGD-enheten. The amount of oxidation is strictly temperature-dependent, and particularly in places with cold water, oxidation is slow. To ensure complete oxidation, the residence time and thus the volume of the aeration basin must be large. The aeration basin is an expensive part of the FGD unit.
Generelt er ikke mekanismen og kinetikken angående sulfit og bisulfit oksidering helt klar. Selv om oksidering med molekulær oksygen kan uttrykkes på denne enkle måte: In general, the mechanism and kinetics regarding sulfite and bisulfite oxidation are not completely clear. Although oxidation by molecular oxygen can be expressed in this simple way:
er reaksjonene meget kompliserte. the reactions are very complicated.
Det er vel kjent at katalytisk autooksidering av oppløst svoveldioksid i vann skjer. Ioner av overgangsmetaller, så som Mn, Fe, Co og Cu er beskrevet i litteraturen som katalysatorer for sulfitoksidering. Også noen heterogene katalysatorer er kjent. It is well known that catalytic autoxidation of dissolved sulfur dioxide in water occurs. Ions of transition metals, such as Mn, Fe, Co and Cu are described in the literature as catalysts for sulfite oxidation. Some heterogeneous catalysts are also known.
I ferskvann, utviser reaksjonsmengden av Fe-katalysert oksideringsprosess en generell klokke-formet pH avhengighet med maksimum mengde rundt pH 2-4. Ved høyere pH-verdier, er ikke det oppløste jern aktivt på grunn av meget hurtig utfelling avFe<3+>hydroksider. In freshwater, the reaction rate of Fe-catalyzed oxidation processes exhibits a general bell-shaped pH dependence with a maximum rate around pH 2-4. At higher pH values, the dissolved iron is not active due to very rapid precipitation of Fe<3+>hydroxides.
katalysert oksidering i sjøvann er forskjellig fra ferskvann. I sjøvann, må oksideringen utføres i et pH-område mellom 4 og 7, og konsentrasjonen av jernioner som er nødvendig er meget lavere. Grunnen for denne forskjell er at sjøvann inneholder store mengder Cl" ioner, hvilket stabiliserer de aktive Fe-komplekser mot utfelling under den tid som er nødvendig for oksidering. Med samme mengde av tilsatt jern (Fe<2+>, Fe<3*>), er oksideringstakten i sjøvann funnet å være mer enn en størrelsesorden høyere enn i ferskvann. ;Ved å tilsette 10-20 ppb av Fe<2+>eller F<3+>til sulfit inneholdende sjøvann, er mengden av S(IV) oksidering omkring 5 ganger høyere enn oksideringsmengder observert i sjøvann uten noen katalysator tilsatt. Uttømming av sjøvann med denne lave konsentrasjon av jern har ingen negativ virkning må miljøet. ;Jern kan tilsettes til sjøvannet i form av oppløselig jemsalter, for eksempel som sulfat eller klorid. Jernsaltene kan tilsettes absorberutgangen eller til sjøvannet oppstrøms fra absorberen eller oppstrøms fra luftebassenget. Oksidasjonstilstanden av tilsatt jern (Fe<2+>eller Fe<3+>) har ingen virkning på mengden av S(IV) oksidasjon, forutsatt at katalysatoren tilsettes i sur effluent. Bare ferrojern bør imidlertid brukes for sjøvann oppstrøms fra absorberen eller oppstrøms fra luftebassenget. Grunnen til dette er den meget hurtige utfelling av Fe<3+>i nøytral eller basiske oppløsninger. Alternativt, kan jernionene tilsettes til systemet gjennom oppløsning av jernmaterialer i en jernoppløsning eller i den sur absorbereffluent. Ved bruk av prinsippene av katodisk beskyttelse og en anode av ferromateriale 0em>s*ål osv) kan mengden av oppløsning av jernioner i sjøvann eller til absorbereffluenten blir styrt ved tilførte strøm. catalyzed oxidation in seawater is different from fresh water. In seawater, the oxidation must be carried out in a pH range between 4 and 7, and the concentration of iron ions required is much lower. The reason for this difference is that seawater contains large amounts of Cl" ions, which stabilizes the active Fe complexes against precipitation during the time required for oxidation. With the same amount of added iron (Fe<2+>, Fe<3*> ), the oxidation rate in seawater is found to be more than an order of magnitude higher than in fresh water. ;By adding 10-20 ppb of Fe<2+>or F<3+> to sulfite-containing seawater, the amount of S(IV) oxidation about 5 times higher than oxidation amounts observed in seawater without any catalyst added. Depletion of seawater with this low concentration of iron has no negative effect on the environment. ;Iron can be added to the seawater in the form of soluble iron salts, for example as sulfate or chloride. The iron salts can be added to the absorber outlet or to the seawater upstream from the absorber or upstream from the aeration basin.The oxidation state of added iron (Fe<2+>or Fe<3+>) has no effect on the amount of S(IV) oxidation, provided that the catalyst is added to acidic effluent. However, only ferrous iron should be used for seawater upstream from the absorber or upstream from the aeration basin. The reason for this is the very rapid precipitation of Fe<3+> in neutral or basic solutions. Alternatively, the iron ions can be added to the system through dissolution of iron materials in an iron solution or in the acidic absorber effluent. By using the principles of cathodic protection and an anode made of ferrous material 0em>s*ål etc) the amount of dissolution of iron ions in seawater or in the absorber effluent can be controlled by applied current.
Med fremgangsmåten og anvendelsen ifølge foreliggende oppfinnelse, slik de er definert med de i kravene anførte trekk, oppnås en økt oksidering av oppløst svoveldioksid i sjøvann. With the method and application according to the present invention, as they are defined with the features listed in the claims, an increased oxidation of dissolved sulfur dioxide in seawater is achieved.
Nyheten ved denne prosessen er de meget små mengder av Fe ioner som er nødvendig, på grunn av de meget aktive komplekser av jern utformet i sjøvann i pH området 4-7. Denne observasjon har ikke vært rapport før. The novelty of this process is the very small amounts of Fe ions that are needed, due to the very active complexes of iron formed in seawater in the pH range 4-7. This observation has not been reported before.
Flere oksidasjonseksperimenter har vært utført i et små-skala-pilotanlegg. Ferri-eller ferrojern (i form av oppløselige salter) blir tilsatt et reaksjonskar inneholdende friskt sjøvann som er gjort surt med oppløst SO2. Bare en langsom oksidasjon er observert når pH-verdien av oppløsningen er under 4, men oksidasjonsreaksjonen starter imidlertid og fortsetter meget raskt når mer sjøvann tilsettes reaksjonskaret og pH-verdien av oppløsningen er i området 4-7. For å nå denne spesifiserte pH, er tilsetningen av sjøvann dimensjonert slik at det naturlig forekommende bikarbonat i sjøvann er tilstrekkelig til å virke som en buffer. Det er også mulig å øke alkaliniteten av sjøvann, og dermed absorpsjonskapasiteten av svoveldioksid, ved å tilsatte kalk eller kalkstein eller oppløsninger av disse til sjøvannet. Several oxidation experiments have been carried out in a small-scale pilot plant. Ferric or ferrous iron (in the form of soluble salts) is added to a reaction vessel containing fresh seawater that has been acidified with dissolved SO2. Only a slow oxidation is observed when the pH value of the solution is below 4, but the oxidation reaction however starts and continues very quickly when more seawater is added to the reaction vessel and the pH value of the solution is in the range 4-7. To reach this specified pH, the addition of seawater is dimensioned so that the naturally occurring bicarbonate in seawater is sufficient to act as a buffer. It is also possible to increase the alkalinity of seawater, and thus the absorption capacity of sulfur dioxide, by adding lime or limestone or solutions of these to the seawater.
Luft eller oksygen blir boblet gjennom karet for å sikre nærvær av oppløst oksygen under oksidasjonsreaksjonen. pH og oppløst oksygen blir kontinuerlig overvåket under reaksjonen, mens prøver for sulfitanalyser blir tatt ved intervallet på noen få sekunder. Sulfitkonsentrasjonene blir bestemt ved jod/tiosulfat-titrering, ved bruk at stivelse som indikator. Kjemikaliene som ble brukt var av analytisk reagensgrad. Karet ble rengjort med HC1 mellom kjøringer for å minimalisere virkningen av katalysator fra tidligere eksperimenter. Air or oxygen is bubbled through the vessel to ensure the presence of dissolved oxygen during the oxidation reaction. pH and dissolved oxygen are continuously monitored during the reaction, while samples for sulfite analyzes are taken at intervals of a few seconds. The sulphite concentrations are determined by iodine/thiosulphate titration, using starch as an indicator. The chemicals used were of analytical reagent grade. The vessel was cleaned with HC1 between runs to minimize the effect of catalyst from previous experiments.
Resultatene viser at mengden av S(IV) oksidasjon er omkring 5 ganger raskere i eksperimenter med 20 ppb Fe-ioner enn uten tilsetning av katalysator. The results show that the amount of S(IV) oxidation is about 5 times faster in experiments with 20 ppb Fe ions than without the addition of catalyst.
