Definitions
- the invention relates to a method for the separation of mercury (Hg) in exhaust gases from
- Incineration plants wherein the existing elemental mercury is oxidized and resulting oxidized mercury is deposited in the process during the treatment and filtration of the combustion exhaust gas.
- Hgel elemental Hg species
- Chloride additives require around ten times the dose for results comparable to bromide. Iodides are similarly effective to bromide but significantly more expensive.
- Activated carbons are used in the flue gas as a third technology, mainly used in plants in the USA (EP 2 260 940 A4). Adsorption or chemisorption mechanisms of mercury take place at the high specific surface of the carbon. For improved deposition of elemental mercury, these coals are often doped or impregnated with further additives (eg Cl, Br, I, S). The production of activated carbons for elemental Hg deposition is complex and energy-intensive.
- the fourth technology to be mentioned is the process patented by Babcock with tetrasulfide addition to the flue gas before the dust separation (EP 0 709 128 A2). The elemental mercury is chemically bound and separated as a solid product together with the filter dust. This requires large amounts of precipitant or a fabric filter.
- the object of the invention is to find a method for the separation of mercury in combustion exhaust gases from power plants, wherein the disadvantages of the prior art are eliminated and a simple method is realized to effect optimal oxidation of the existing mercury in combustion exhaust gases.
- Metering is metered into the combustion exhaust gas, wherein the metering takes place in the flue gas path to the firebox, but the increased formation of oxidized mercury is carried out in a temperature range ⁇ 500 ° C, that the material consists essentially of inorganic and non-combustible material,
- That the powdered, catalytically active material is preferably made of iron (III) oxide,
- That the metering device is carried out for the introduction of the material after the economizer, after the air preheater or after dedusting,
- the powdery, catalytically active material consists of heavy metal oxides and hydroxides, wherein oxides and hydroxides of iron, copper, manganese, zinc, vanadium tungsten, cobalt, chromium and nickel are applied.
- the dosing quantities are so small in comparison to the accumulating filter dust that its quality and subsequent use is not adversely affected.
- an addition to the dedusting system and a separation on facilities for flue gas desulfurization are also possible. Homogeneous distribution should be taken into account when adding the catalyst to the flue gas.
- the measure proposed here is based on a method according to the invention, which manages with little equipment and avoids large-scale plant retrofits.
- the catalytic material is in this case distributed from a silo by means of discharge and conveying air to different metering lances and directly, as homogeneously distributed, introduced into the exhaust stream.
- the elemental mercury is thereby converted into the oxidized form on contact with the iron (III) oxide.
- subsequent facilities for emission control such. As the dust or desulfurization, then the deposition of oxidized mercury takes place.
- the catalytically active material preferably iron (III) oxide
- the catalytically active material is deposited together with the filter dust on the dedusting plant or in the desulphurisation plant.
- the catalytically active material is not flammable or explosive, which means that the process is characterized by significantly lower safety risks.
- the mechanism of the improved Hg deposition is based on the shift of the poorly water-soluble elemental Hg species to the highly water-soluble and thus much better depositable, oxidized mercury species (Hgox).
- the process uses the halides present in the fuel or exhaust gas as reactants for elemental Hg. By adding the catalyst, this oxidation reaction proceeds more efficiently at lower temperatures.
- the material used has a high specific surface area (m 2 / g) and as a result is much more reactive than oxidatively active constituents occurring natively in filter dust.
- an exhaust gas purification device (dedusting or desulfurization) must be present.
- the catalytic function of the material is given both during the flight phase in the exhaust gas and during the dwell phase in the filter cake of dedusting.
- the overall degree of separation of Hg increases via downstream equipment for flue gas purification.
- Adsorptive deposition effects of mercury can also take place directly on the metered material.
- the method is used for oxidation and thus improves the separation of mercury in combustion exhaust gases from power plants with the addition of a powdery, catalytically active material having mean grain diameters ⁇ 35 pm, preferably iron (III) oxide.
- the powdery material is introduced by conventional dosing devices (eg screw conveyors, blowers) in the
- Combustion gas is metered and existing cleaning equipment, such as the electrostatic precipitator or the wet
- the catalytic effect is enhanced in the formation of a flow-through filter cake.
- the catalytic effect is shown in the temperature range of ⁇ 500 ° C, resulting in suitable dosing by economizer, air preheater or after dust filter.
- the catalytic effect is caused by base metals or their oxides.
- Applications are possible that use heavy metal oxides and hydroxides. These can be: oxides and / or hydroxides of iron, copper, manganese, zinc, vanadium tungsten, cobalt, chromium and nickel.
- the material used is essentially inorganic and nonflammable.
- the method further serves for the separation of acidic exhaust gas components, such.
- acidic exhaust gas components such as hydrochloric acid (HCl) and sulfur oxides (SO2, SO3), if metals are metered in the form of hydroxides.
- the dosed material acts as a catalyst and adsorbent for mercury and
- the supply of the material according to the invention takes place behind the boiler / combustion 1 and / or the air preheater 2 and / or the dedusting 3 as catalytic material.
- the catalytically active material is metered into the combustion exhaust gas via known metering devices, such as screw conveyors or blowers.
- Lignite combustion are basically the boiler / combustion 1, followed by an air preheater 2, a dedusting 3, a desulfurization 4 and a chimney / cooling tower 5 given.
- the material according to the invention is to be metered into a hard coal combustion, metering takes place in the ongoing process behind the boiler / combustion 1, the air preheater 2 and / or the catalytic denitrification 7 and / or the dedusting 3. After dedusting 3 desulfurization 4 takes place towards the chimney / cooling tower. 5
- the material according to the invention is metered in via the boiler / combustion 1, the air preheater 2, the dedusting 3. After the dedusting 3, the desulfurization 4, the catalytic denitrification 7, takes place towards the chimney / Cooling tower 5.
- customary dosing devices such as screw conveyors or blowers are used.
- the material preferably iron (III) oxide
- the feed of the catalyst was carried out via a pneumatic conveyor line from the silo via a lance system with 12 metering points distributed over the cross section of the exhaust passage.
- the deposition of the catalyst was carried out together with the filter dust on electrostatic precipitator.
- the average grain diameter of the iron-containing catalyst was 1.5 pm. Concentrations in the raw gas between 35-150 mg / Nm 3 f. set and achieved in Table 1, Figure 2, oxidation results.
- the oxidized Hg content was ⁇ 4 pg / Nm 3 tr in the usual range of total mercury inventory of 15 pg / Nm 3 tr. After electrostatic precipitator, this results in a proportion of about 25% oxidized Hg. Already with dosing quantities around 35 mg / Nm 3 f. this share increased to almost 50%. With maximum cat concentration of 150 mg / Nm 3 f. a proportion of oxidized mercury of 57% was reached.
- the material preferably iron (III) oxide, was added to the flue gas in the lignite fired power plant after air preheater / before electrostatic precipitator at temperatures around 170 ° C.
- the feed of the catalyst was carried out via a pneumatic conveyor line from the silo via a lance system with 12 metering points distributed over the cross section of the exhaust passage.
- the deposition of the catalyst was carried out together with the filter dust on the subsequent in the process electrostatic precipitator.
- the average grain diameter of the iron-containing catalyst was 1.5 pm. There were concentrations in the crude gas of 50 and 210 mg / Nm 3 f. tested and shown in Table 2, Figure 3, shown
