Increased attention is to be paid in particular to technologies used for process gas monitoring at the kiln inlet area as well as modern LiDAR sensors applied on conveyor belts. In combination with analyzing parameters of condition in different machineries of a cement plant, added value can be created leading e.g. to increased production rates and higher capital efficiency.","PeriodicalId":135175,"journal":{"name":"2019 IEEE-IAS/PCA Cement Industry Conference (IAS/PCA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128954831","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"A Holistic Approach for Alternative Fuel Utilization in Cement Manufacturing","authors":"Dominik Aufderheide, Luigi Di Matteo","doi":"10.1109/CITCON.2019.8729091","DOIUrl":"https://doi.org/10.1109/CITCON.2019.8729091","url":null,"abstract":"The co-processing of alternative fuels within the cement manufacturing process is a long-established measure towards a more sustainable operation of modern cement plants. However, even if the usage of alternative fuels (AF) becomes a common-sense approach for the reduction of fossil fuels in the clinkering process, there are still numerous examples of practical difficulties and associated unused potentials. In this context the development of a holistic approach for AF utilization and co-processing becomes a major goal for all stakeholders involved in the realization. Such an approach would consider all aspects of an AF project and the corresponding implementation framework in order to understand the requirements derived from circular economic value and supply chains. The paper will present such a holistic approach based on practical case studies which involve orienting guidelines for defining logistic frameworks for supply chains of AF, measures for the assurance of fuel quality in the cement plant, efficient handling of material flows associated to AF utilization and concrete examples of fuel injection and corresponding process questions. The practical examples from different implemented projects represent best-practice approaches for AF utilization.","PeriodicalId":135175,"journal":{"name":"2019 IEEE-IAS/PCA Cement Industry Conference (IAS/PCA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130847704","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Leveraging Control System Evolution for Plant and Personnel Efficiency","authors":"G. Davis, Thomas Jankowski, G. Kemper, J. Holmes","doi":"10.1109/CITCON.2019.8729115","DOIUrl":"https://doi.org/10.1109/CITCON.2019.8729115","url":null,"abstract":"With advancing technology, plant-based automated control systems (ACS) eventually reaches the end of its useful life and an upgrade is required. ACS upgrades can be driven by reliability issues, system expansion limitations, or advanced networking security standards to name a few. Within an automated control system platform, there are several layers of automated resources, the enterprise/business level, the manufacturing execution system (MES)/operator control level, the controller level, and the device/instrumentation level. Each of the resource layers have an ideal lifecycle window that is tied to the evolution of the vendor system or hardware that is being utilized for automation. While the device/instrumentation level resources may have a longer life cycle, the enterprise or business level resources have a shorter life cycle due to a more frequent update timeline of vendor software and systems support.Recent patterns for increased connectivity demand on the enterprise level for analytical analysis coupled with demands for advanced networking security standards have accelerated the enterprise/business level’s evolution. Inherently, these demands for connectivity have put a strain on the lower MES/operator and controller resource levels of the control system to gather and process this required field information. But these demands are not only limited to the ACS components as the plant must maintain a technical staff outside of a traditional IT department to support the new software and hardware systems.This paper describes the levels within an automated control system and how a management team can leverage the evolution of the control system in the plant to meet the growing demands of the enterprise level while also raising the level of technical aptitude of plant employees required to support the modern system design. It will describe the benefits of giving plant operators access to enhanced process information to increase plant reliability and using web-based tools to improve efficiency of plant electrical and maintenance teams. It will describe how modern networking components can utilized to identify failures without requiring a technician to be exposed to process or electrical hazards. The examples included in the paper show how the evolution within a control system have an impact on more than just the data the enterprise level receives.","PeriodicalId":135175,"journal":{"name":"2019 IEEE-IAS/PCA Cement Industry Conference (IAS/PCA)","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116978266","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Vintage Low-Voltage Motor Control Centers – Replace or Upgrade?","authors":"D. Durocher, M. Hussey","doi":"10.1109/citcon.2019.8729108","DOIUrl":"https://doi.org/10.1109/citcon.2019.8729108","url":null,"abstract":"Low-voltage motor control centers are universally applied in process industries. These electrical assemblies are perhaps one of the most dynamic in industry, ever changing as low-voltage motor loads are constantly added and modified in response to necessary process revisions and upgrades. As existing low-voltage motor control centers (MCCs) approach 40 to 50 years age, industry users are challenged with a decision to replace vintage MCCs approaching their end of life, or consider upgrade of existing assemblies. This paper will discuss upgrade versus replace alternatives, addressing UL 845 North American industry standard requirements and how this affects design, installation and maintenance of both upgraded and new MCCs. Application issues including considering the cost of replacing load cables versus re-use of existing cables, high-resistant pulsing ground systems and opportunities for process improvements and network communications that leverage the latest technology will be discussed. Finally, a case study comparing the alternative of replacing an existing MCC versus a field upgrade based on changing out all exiting starter and feeder circuit breaker units and an estimate of the total installed cost for both MCC replacement and upgrade for this application will be reviewed.","PeriodicalId":135175,"journal":{"name":"2019 IEEE-IAS/PCA Cement Industry Conference (IAS/PCA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132625481","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
