1 OPTIMIZED INTEGRAL Flue Gas Cleaning System SPECO LTD.

2 SUMMARY BUSINESS FIELDS BRIEF HISTORY

3 To solve the problems related to the removal of pollutants such as Dioxins/Furans, Nitrogen Oxides, Dust and Heavy metals and of Acid Gases, SPECO has developed a complete range of reductoin/oxidation or adsorption, adsorption /neutralization and filtration processes which provide the best answer to the various air quality control requirements. AIR & GAS QUALITY CONTROL PROCESS Selection Index Flue Gas Treatment System

4 DRY & SEMI-DRY PROCESS Dry Process The dry process involves not only filtration but also injection of a reagent in powder into the gas stream to be scrubbed. Anti-corrosion cooler Lime Particle conditioner Fabric filter Clean gas No water is used or discharged and the stack plume is almost non-existent. Flue gas Residues Fan Industrial boiler Industrial waste incinerator Municipal incinerator Power plant Residue treatment before dischange Semi-Dry Process This process is suitable when acidic gases such as HCl, HF, SOx from incinerator, waste heat boiler cleaning performances are required. Activated carbon is mixed with lime slurry for adsorbing the Dioxins/Furans and various other residual pollutants, in particular gaseous heavy metals such as mercury. Lime Clean gas No water discharge as the spray water vaporizes in reactor Fabric filter Flue gas Reactor Residues Fan Industrial boiler Industrial waste incinerator Municipal incinerator Power plant Residue treatment before dischange

Semi-dry reactor The inlet reactor tower has been carefully designed to provide an even distribution of gas to each of the flow tubes with minimal pressure drop.

Acid gases are converted to neutralized salts and still have a long residence left in the vessel to ensure complete drying of these products.

Also, the outlet has been designed so that as the gas is accelerated back to the dust carrying velocities, the velocities will remain sufficiently high as to prevent fallout of particulate in the

5 Semi-dry reactor The inlet reactor tower has been carefully designed to provide an even distribution of gas to each of the flow tubes with minimal pressure drop. The flue gas and reagent spray the exit of flow tubes and begin to expand into the scrubber vessel. Acid gases are converted to neutralized salts and still have a long residence left in the vessel to ensure complete drying of these products. So, there are no internal devices and no horizontal ledges in the hopper area where buildups could occur. Also, the outlet has been designed so that as the gas is accelerated back to the dust carrying velocities, the velocities will remain sufficiently high as to prevent fallout of particulate in the outlet area of the scrubber vessel. Nozzle Slurry Liquid Inlet Orifice Compressed air Air lnlet Orifice Target Bolt Reduced Orifice Key Slurry steam impingement on a target bolt causes quick, effective tearing of the liquid into filaments and large droplets. High-velocity air creates high shear forces on the droplets, breaking them into smaller droplets. A reduced-opening orifice generates additional shearing to reduce mean droplet size. Holes in nozzle tip shape the spray and provide a sharp cut off on maximum droplet size. Orifice Atomization Nozzle Tip Key Advantages A complete lance / nozzle assembly can be changed in less than 5 minutes during plant operation. Routine cleaning of the nozzle and lance is accomplished with the nozzle in place. Shield air protects the compressed air and slurry lines. Quick disconnects are provided for each hookup to the lance assembly. Correct alignment of the spray nozzle in the gas flow tube is ensured.

6 WET PROCESS Wet Process The wet process involves gas GRANILAB scrubbing which leads to the saturation temperature and to the Absorption of acid gases such as HCl, HF, SOx by scrubber with using lime and / or soda. Fine particles including heavy metals and mist are additionally collected in Electro-filtering-Module(EFM), to produce a cake containing stabilized heavy metals and clear water which can be discharged to the environment. This process give excellent results, irrespective of the fluctuation or quantity of pollutants entering the system the amount of reagent used is close to stoichiometric ideal. The quantity of residues to be disposed of is low and additional treatment is fairly simple.

7 Edv series The EDV system consist of GRANILAB spray towers comblined with FILTERING and / or ELECTRO-FILTERING VENTURI MODULES They include a number of technological innovations, which allow the systems to meet even the most stringent air quality control requirements. Nozzle The nozzle are designed to handle concentrated slurries without clogging, scaling, abrasion and corrosion. Droplet size is design variable of nozzle technology. The closely controlled droplet sizing is essential for optimum particulate removal and acid gas absorption. These technological advantages form a deciding factor for the end-user, since they allow large quantities of dust and pollutants to be captured without clogging and require very little fresh water due to a high recycling rate in the scrubbing loops. Electro-filtering Venturi It fitted with a dynamic precipitation electrode consisting in a curtain of electrically charge water droplets sprayed in counter flow pattern. Its efficiency is independent of size distribution and electrical properties of the particles to be captured.

8 SCR & SNCR PROCESS SCR process SCR (Selective Catalytic reduction)system, using the catalyst removal not only NOx but also Dioxin & Furan in Flue gas at same time, as very nice efficiency. Injecting ammonia upstream from the reactor reduces nitrogen oxides. The reaction is almost efficient at flue gas temperature between 200 and 300 on successive layears of catalyst lining the reactor.

10 Removal & destruction process of dioxins & furans In order to meet the specific needs of each type of facility most efficiently and economically, there are four different dioxin and furan emission control processes. Among these processes, two in particular enable the combined collection and destruction of dioxins and furans. Experience gained from their applications since Stack emission guarantee of less than 0.1ng-TEQ/Nm (Expected value : 0.01ng-TEQ/Nm) Industrial waste incinerator Municipal incinerator Chemical plant Nitric Acid plant Reagent Activated carbon Reagent Reagent Activated carbon Flue gas Residues Fly ash Bleed Ammonia Reagent Activated carbon GAS cleaning Bleed Residues
