水泥工业是碳排放量最大的工业部门之一。它是负责约5%的人为CO2在世界上。因此，它是一个相关的工业部门的CO2排放管制战略。考虑到水泥工业在克罗地亚的重要性，由于克罗地亚即将成为欧盟成员国，本文分析了克罗地亚水泥工业减少CO2排放的潜力。有几项措施可以减少水泥生产过程中的二氧化碳排放量：利用废热作为替代能源;二氧化碳捕获和储存技术;减少熟料与水泥的比例;使用替代燃料和生物质燃料;使用替代原材料;节能燃烧工艺。当今水泥生产中最节能的技术是使用回转窑以及多级预热器和煅烧炉。由于水泥煅烧炉的使用是一项相对较新的技术，因此仍需进一步改善其操作条件。本文还重点介绍了计算流体动力学（CFD）模拟领域的研究成果，用于过程和燃烧排放的调查。上述措施加上数字调查可以减少克罗地亚水泥制造对环境的影响，并使其与欧盟水泥制造商更具竞争力。
Cement industry is one of the largest carbon emitting industrial sectors. It is responsible for about 5% of anthropogenic CO2in the world. Therefore, it is a relevant industrial sector for CO2emission regulation strategies. Bearing in mind the importance of cement industry in Croatia, and because of the fact that Croatia will soon become an EU member state, the present paper analyses the potential to reduce CO2emission in the Croatian cement industry. There are several measures that can reduce CO2emissions from the cement manufacturing process: the use of waste heat as an alternative source of energy; CO2capture and storage technologies; reduction of clinker to cement ratio; the use of alternative and biomass fuels; the use of alternative raw materials; an energy efficient combustion process. The most energy efficient technology for cement manufacturing today is the use of a rotary kiln together with a multi-stage preheater and a calciner. Since the use of cement calciners is a relatively new technology, further improvement of their operating conditions is still needed. This paper also highlights the results of research in the field of computational fluid dynamic (CFD) simulations that are used for the investigation of process and combustion emissions. The above mentioned measures together with numerical investigations can reduce the effect of cement manufacturing in Croatia on the environment and can make it more competitive with cement manufacturers from the EU.
