3 Foreword European Cement Research Academy Welcome to the ECRA seminar programme for 2011! We have five seminars scheduled over the course of the year covering the topics of monitoring of industrial emissions, pretreatment handling, storage and feeding of waste fuels, bypass systems, cement grinding and the interaction of cement and admixtures. In addition we will have a one-day conference on new cements and innovative binder technologies which will summarise current aspects of new cement developments. For the first time ECRA provides a training course for young engineers with the focus on clinker and cement production. The two-day training will give an introduction into cement process technology as well as environmental and product aspects. A third day will be dedicated to a plant visit enabling the participants to discuss these topics on-site with practitioners. Continuing our close cooperation with our members this year s venues are Spain, Italy, Austria, Germany, the United Kingdom and Latvia. Most seminars offer the opportunity to visit a cement plant and all include an evening dinner offering ample opportunity to network and exchange views with fellow participants and the speakers in an open atmosphere. Last but not least, ECRA is committed to providing seminars to meet your needs. To help us focus as much as possible on your individual expectations of the seminar you are attending, we invite you tell us when you register about specific questions or issues which you feel should be addressed. We will make every effort to accommodate your wishes. Please also feel free to let us have your general comments and suggestions, which are always welcome. You will find our contact details on Page 8. We hope this year s programme is of interest and look forward to hearing from you. Daniel Gauthier Chairman of the Technical Advisory Board Martin Schneider Managing Director

4 Conference Seminars 4 5 May 2011 C11-01 New Cements and Innovative Binder Technologies May 2011 S11-01 Current Developments in Continuous Emission Monitoring Objective: Overview of the properties and the potential of well-known and new binder technologies Target group: Sales, marketing and consulting engineers, R&D staff Objective: The seminar will provide a comprehensive overview on the latest developments in continuous monitoring of industrial emissions Target group: The seminar will target experienced environmental and process engineers as well as technicians. The seminar is also intended for experienced experts from the cement and lime industry Against the background of the growing demand for cement worldwide, the cement industry has been optimizing its cement within the framework of current cement standards. The potentials, which these standards still provide with respect to reducing for example clinker content in cement and at the same time taking advantage of alternative materials, will be pointed out in this seminar. Recent findings on new cements will also be reported. Such cements are still under research and development as regards their production and their performance in concrete. These new cements are either not based on limestone as starting material or exhibit a ratio of calcium to silica which is lower than in today s cement. Both approaches would result in a good CO 2 balance. The seminar will give an overview of the current status of research on these new cements with dedicated focus also on the potential performance in mortar and concrete. Development of cements based on current cement standards: ternary binder systems (clinker, limestone, blastfurnace slag) calcined clays a potential cement constituent Development of cements beyond the current cement standard CEM X cements, glass cement Celitement a calcium-based development Novacem a magnesium-based development Calera cement constituents from carbon capture Venue: Cementos Molins plant, Sant Vicenç dels Horts, Spain (nearest airport: Barcelona) The seminar will give a summary on the state of the art of continuous mercury measurement techniques in the cement industry. Representatives of some European manufacturers of continuous mercury measuring devices will give an account of the latest developments with special consideration of the requirements in the cement industry. A second aspect of the seminar which has lately come into focus is the quasi-continuous measurement of PCDD/PCDF emissions. First experiences with such measuring systems will be reported. This item will be expanded by a comprehensive overview on the actual knowledge about the formation and conversation of POP s in cement kiln systems. In addition, the requirements of quality assurance based on the European standard EN will be covered in detail. The guideline DIN EN applies all over Europe and deals with the calibration and functioning of continuous measuring devices as well as the corresponding operational activities and the computation of emission data. Legal requirements in state of the art in emission monitoring in the European Union Quality assurance of measuring systems: European standard EN and its practical application Continuous monitoring of mercury emissions: Introduction to the specific characteristics Monitoring of mercury emissions with thermocatalytical devices Monitoring of mercury emissions with wet-chemical devices Quasi-continuous monitoring of PCDD/F emissions in the cement industry Formation and conversion of POPs in cement kiln systems examples and measurement results Venue: Buzzi Unicem plant, Robilante, Italy (nearest airport: Turin) 4

5 Seminars June 2011 S11-02 Cement Grinding Technologies September 2011 S11-03 Pretreatment, Handling, Storage and Feeding of Waste Fuels Objective: Overview of cement grinding technologies with focus on potential energy reduction and throughput optimization Target group: Process managers, process engineers, mill operators, environmental engineers Objective: Comprehensive overview on all aspects of pretreatment, handling, storage and feeding of waste fuels. Target group: Environmental and process engineers with a basic knowledge of cement manufacturing and alternative materials Energy consumption in raw material and cement grinding has been successfully reduced in the cement industry over many years. Today there are various different grinding technologies in use. There is more than one hundred years experience with cement grinding in ball mills; this mill type is very interesting because of its high reliability and the cement properties. Because of the rising energy costs in recent years high pressure comminution with vertical roller mills, high pressure grinding rolls or with the horizontal roller mill became more important. The specific energy demand of these grinding systems is considerably lower. In this context the seminar gives an overview about the existing cement grinding technologies and their advantages and disadvantages. It will provide the opportunity to discuss essential grinding parameters and the possibility of mill optimization. The use of alternative materials is still an issue of growing concern for the European cement industry. Beside the burning behaviour of waste fuels, the suitable pretreatment, handling, storage and the feeding of waste fuels can be a real challenge for the plant operator. The seminar is targeted at giving a comprehensive overview on these aspects with a focal point on the tailored pretreatment of different materials. In addition, the cement European legislation concerning the use of alternative materials will also be discussed. In this context, the participants will also receive an update about the European activity on the standardisation of alternative fuels. The seminar will take place at a European cement plant and participants will have the opportunity for a plant visit. Introduction to cement grinding Cement grinding with ball mills Cement grinding with vertical roller mills Cement grinding with high pressure grinding Cement grinding with horizontal roller mills Mill optimization Legal requirements on the use of waste Suitable alternative fuels for cement production (requirements, characteristics, chemical and physical aspects) Pretreatment processes for alternative fuels Requirements on a safe and appropriate handling, storage and feeding Sampling and quality criteria for alternative fuels Analysis of alternative fuels Venue: CEMEX plant, Broceni, Latvia (nearest airport: Riga) Venue: Lafarge plant, Retznei, Austria (nearest airport: Graz)

6 Seminars 5 6 October 2011 S11-04 Bypass Systems 9 November 2011 S11-05 Cement and Admixtures Objective: Improved knowledge about the technical design of bypass systems and their impact on product quality and emissions Target group: Process engineers, environmental and chemical engineers in the cement industry with experience in process engineering in cement manufacture Objective: Overview of interactions between cement and concrete admixtures Target group: Sales, marketing and consulting engineers, R&D staff Sulphur, alkalis and chlorides form volatile compounds in the clinker burning process, which can affect the production process negatively. As a consequence, it is important to limit these cycles and, if necessary, to reduce them. In recent years, those cycles have increased in many kilns due to higher chloride inputs from alternative fuels and raw materials. In some cases SO 2 abatement measures have increased sulphur loads to the kiln. As a consequence, more and more cement kilns are equipped with bypass systems. This seminar is focused on the different technologies of bypass systems, their efficiency in limiting material cycles, their effect on gaseous emissions and emission reduction measures. Furthermore, the options to use bypass dust in cement and cementitious products or for other purposes are taken into account. In order to optimise the admixture effect or to avoid unscheduled effects, a detailed understanding of possible interactions in the concrete and especially between cement components, e.g. blastfurnace slag, limestone or fly ash and admixtures is necessary. The seminar will give an overview of the wide range of common and new concrete admixtures. Participants will gain extended basic knowledge about the interactions between cement and concrete admixtures. New results of several research activities on the different operative mechanisms and the influence of concrete admixtures on the hydration process and on other properties of fresh and hardened concrete will be presented and discussed. Design of bypass systems Removal efficiency of chlorine and sulphur in bypass systems Gas treatment and impact on emissions Technical modelling of riser as design criteria of bypass systems Options for the utilization of bypass dust Bypass dust treatment Experiences with bypass systems Introductory general report: History, facts, application, effects Plasticizers and superplasticizers Air-entraining agents Retarders and hydration inhibitors Accelerators Shrinkage reducing admixtures Chromate reducing agents Venue: Ribblesdale plant, Clitheroe, UK (nearest airport: Manchester) Venue: ECRA, Duesseldorf, Germany (nearest airport: Duesseldorf International)
