How can industrial operators meet those challenges without compromising their ability to carry out their functions ef? ciently ?The use of a wider range of fuels, ranging from natural solid fuels to urban waste and alternative residue-derived fuels, provides part of the answer. Partnership with Lhoist Group, one of the world’s leading manufacturers of lime and lime-based products provides another part of the answer.Lhoist is the perfect partner to help you 3Whatever the industrial sector – municipal waste incineration, glass making, the steel industry, or mineral extraction - the common waste by-product of the industrial process is emission discharged into the atmosphere. The amount and toxicity of ? ue gas emissions is increasingly being curbed by legislation, in particular the Integrated Pollution Prevention and Control Directive.The answer from Lhoist Group, the expert in FGT, is Sorbacal® SP, a unique lime-based ? ue gas treatment. Use of Sorbacal® SP as an alternative to expensive and extensive capital investment in new FGT plant allows industrial users to remain competitive in the globalised marketplace.*Sorbacal® is a registered trademarkof Lhoist Recherche et Développement S.A.Sorbacal® SP product and process are patented namely under EP 0861209, US 6322769, CZ 294010, PL 185091ContentsDry Flue Gas Treatment:From simple to easy 4Sorbacal® SP: a top quality hydrated lime for the dry process dedicated to achieve the latest emission limits 5Bene? ts of the high speci? c surface area and large porevolume of Sorbacal® SP 6Buy absorbent by weight, not stoichiometric ratio 7Sorbacal® SP easily adapts to your process 8Sorbacal® SP: use it now 10Skilled service teams 12Frequently asked questions 14Pollutants(Nm³ ; dry gas at 11%O2)Unit Dir. 2000/76 For waste incineration100% daily average100% average value for 1/2 h97% average value for 1/2 hDustmg/Nm310 30 10Organic substances, expressed as CO 10 20 10SO2 50 200 50HCl 10 60 10HF 1 4 2NOxExisting units < 6tph 400Existing units > 6tphor new intallations200 400 200PCDD/PCDF dioxins and furans ng TEQ/ Nm³ 0,1Heavy metals Average value for 1/2h min. to 8h max.100% 97%Hgmg/Nm30,05 0,1Cd+TI 0,05 0,1Sb+As+Pb+Cr+Co+Cu+Mn+Ni+V 0,5 1Dry Flue Gas Treatment (FGT) has become the predominant solution for modern ? ue gas facilities.

This high performance lime has been developed by the Lhoist Group to increase the ? exibility and effectiveness of the dry process. Due to its large speci? c surface area and high porous volume, Sorbacal® SP achieves superior pollutant removal and reduces operating costs.Sorbacal® SP a top quality hydrated lime For the dry process, dedicated to achieve the latest SO2 - HCI - HF emission limitsStandard hydrated limeSorbacal® SP Standard hydrated lime Sorbacal® SPPurity (Content of Ca(OH)2) > 90% > 93%BET Speci? c surface area < 18 m²/g > 40 m²/gTotal pore volume (0-1000 Å) < 0.10 cm³/g > 0.20 cm³/gd50 4-6 µm 5-8 µmBene?ts of the high speci?c surface area and large pore volumeof Sorbacal® SP6Reduction of the fresh absorbent dosage The high speci?c surface area (up to three times higher than normal hydrated lime), combined with the higher pore volume, results in a reduction of up to 50 % in the amount of Sorbacal® SP used when compared to standard hydrated lime. Reduction of the residue generationAs a result, dry processes using Sorbacal® SP instead of standard hydrated lime generate signi?cantly less ?ue gas cleaning residues.Extension of dry process to new temperature zones The high ef?ciency of Sorbacal® SP in a wide temperature zone ranging from 100 to 400°C brings about a complete re-engineering of the FGT process. Specially welcome inthe case of a SCR Denox low temperature or high temperature electrostatic precipitator in the industrial market.0,5Sorbacal® SPCa(OH)2 standard1 1,5 2 2,5 3 3,5 4HCl removalCapture ef?ciency (%)Buy absorbent by weight, not stoichiometric ratio 7DesulphurisationCa(OH)2 + SO2 + ½ O2 > CaSO4 + H2OHalogenated acids removalCa(OH)2 + 2 HCl > CaCl2 + 2 H2OCa(OH)2 + 2 HF > CaF2 + 2 H2OFrom theory…… to practiceAs hydrated lime has the highest neutralisation capacity, and considering the realistic values achieved by many users in practice, less than 2 kg of Sorbacal® SP should be suf? cient to neutralise 1 kg of HCl. Less than 3 kg of Sorbacal® SP should be suf? cient to neutralise 1 kg of SO2.Consequently, in the case of urban waste incineration for example, the lime dosage varies from 8 to 18 kg per ton of garbage (depending on the chlorine and sulphur load of the waste).1 kg of HCl can be neutralised by 1 kg of Ca(OH)21 kg of SO2 can be neutralised by 1.2 kg of Ca(OH)20,5NaHCO3Na2CO3Ca(OH)20,75 1 1,25 1,5HCl - Neutralisation Capacityamount of sorbent [kg]amount of neutralised HCl [kg]43.532.521.510.500,5NaHCO3Na2CO3Ca(OH)20,75 1 1,25 1,5SO2 - Neutralisation Capacityamount of sorbent [kg]amount of neutralised SO2 [kg]4.543.532.521.510.50Hydrated lime - Ca(OH)2 - is the absorbent with the highest neutralisation content in dry absorption as these global chemical reactions show: 8Sorbacal® SP easily adapts to your processSorbacal® SP in a dry process with residue recirculation reduces the recycling rate and improves performanceSeveral dry ? ue gas processes designed for standard hydrated lime are based on the recycling of a large quantity of absorbents and operate at low temperatures. It is possible to reduce the recirculation rate and improve the removal performance by using Sorbacal® SP.Sorbacal® SPS: especially for sulphur removalSorbacal® SPS improves performance on SO2 removal at temperatures between 150°C and 350°C. Sorbacal® SPS has the same physicochemical characteristics as Sorbacal® SP but is doped to improve the af? nity of lime with SO2.9Multiple injection points to optimise the performanceBy injecting Sorbacal® SP at several points, specially selected by Lhoist’s service team, and starting from the same silo (meaning no additional investment), we can further optimise performance and reduce consumption.Combination of dry Sorbacal® SP injection and semi-wet process (called ¾ dry process, MKT or Multi purgo)By combining Sorbacal® SP injection with a semi-wet process using milk of lime atomiser (based on Sorbacal® Q – quicklime - for example), we can optimise performance and maximise savings. The semi-wet process using milk of lime prepared from quicklime is renowned for its low cost of absorbency but can experience some limitations to cope with unsteady ? ue gas conditions such as ? ow rate, acid gases concentration and speci? c ? ue gas temperature issues. Sorbacal® SP injection broadens the typical operating conditions of the semi-wet process and boosts the performance of the ? ue gas treatment with only marginal investment needed.Ultra high temperature injectionThe outstanding performance of Sorbacal® SP injection in the temperature range of 850 to 1050°C on SO2 removal means that more than 90 % of the SO2 can be removed. This selective SO2 removal widens the possibilities of combined multiple point injection. In particular, the ? rst stage injection at ultra high temperature captures the majority of the SO2 and then the second stage injection of additional Sorbacal® SP before the ? lter, after the cooling process captures the HCl, HF and the residual SO2.Sorbacal® SP Sorbacal® SPS10Sorbacal® SP...use it now “On–demand performance”using Sorbacal® SP Sorbacal® SP enables the user to comprehensively tune the performance as a function of the evolution of ? ue gas conditions such as volume of ? ue gas and concentration of the pollutants or following the tightening of legislation without additional investment. 25% to more than 99% removal are possible.Ready for todayAs Sorbacal® SP is delivered to site as a free ? owing powder, it is ready to use without needing additional cost intensive treatment such as milling. Sorbacal® SP can be injected in a wide range of dosage rates without any modi? cation of the injection device or extra investment.Ready for the futureWith Sorbacal® SP, daily average emissions lower than 2 mg/Nm³ HCl and lower than 8 mg/Nm³ SO2 have already been achieved in municipal waste incinerators.A ZERO investment and risk-free moveSorbacal® SP is the perfect substitute to normal hydrated lime in a plant facing the evolution of the standards. Without any investment, a simple replacement of the current normal hydrated lime using the same silo boosts the performances of your dry process.A comprehensive European production networkToday, Sorbacal® SP is produced in six plants throughout Europe and the capacity is continuously being adapted to market needs.
