Staged combustion deNOx technology for calciners19 July 2021, Published under Cement NewsUnder increasingly stringent pollutant emission standards, deNO x systems are widely used in Chinese cement production. As the calciner is relatively flexible and adjustable in its design, it is a key piece in the process for NO x emissions reduction. Tianjin Cement Industry Design and Research Institute Co, Ltd has been researching NO x emissions reduction technology in cement manufacturing for more than two decades, and in this article charts the development of staged combustion deNO x ... |
Mitigating acid gas emissions11 December 2018, Published under Cement NewsIn this month’s Technical Forum, Dr Michael Clark examines acid gas emissions from cement kilns. Understanding harmful acid gas emissions, such as hydrogen chloride, is required before investing in mitigation strategies. Before investing in new raw material quarries, a better understanding of acid gas emissions is required Emissions from cement kilns are a growing focus of environmental authorities around the world. This month’s Technical Forum will look at the causes and mitiga... |
Van Aalst partners Scania in cement carrier project11 October 2018, Published under Cement NewsVan Aaslt has contributed in the development in the first Tier III Scania self-discharging cement carrier called 'NACC Alicudi'. The 120m vessel operates Scania IMO tier III diesel engines with a unique pneumatic conveying system for loading and unloading cement, fly ash and granulated slag. The vessel had to fit the Scania Selective Catalytic Reduction (SCR) system in the engine room deckhouse, which was smaller as the previous non-SCR equipped engine room deckhouse. This resulted into l... |

Finding the missing link13 December 2017, Published under Cement NewsIn 2015 Çimsa Çimento’s Mersin plant, Turkey, suffered an increasing number of cyclone blockages, causing severe interruptions to the facility’s grey cement Line 1. After unsuccessful attempts to find the reason for the blockages, a kiln inlet process gas measurement system from sick was installed to provide the missing link between the sulphur content in the kiln process gases and unwanted production downtime. By Felix Bartknecht, SICK AG, Germany, and Sezin Arıkan, Çimsa Çimento Mersin, T... |
Kiln emissions – more than just hot air01 February 2017, Published under Cement NewsIn last month’s Technical Forum we promised to return to the topic of cement kiln emissions, which were said to be both simple and complex, benign and noxious. The challenge is to see the broad simplicity, which then allows the increasing complexity to be understood. By Dr Michael Clark, UK. Kiln emissions include a wide range of gases – some benign but others noxious At the macro level cement kiln emissions are indeed simple. The raw materials used for manufacturing clinker are... |
