To SCR or SNCR?21 November 2022, Published under Cement NewsWhile in some cases the choice between SCR and SNCR technology for NOx reduction appears straightforward, there is a middle way that enables the use of the less expensive option of SNCR technology. Lechler explains how cement producers can benefit from its high-efficiency SNCR technology. By Dipl Ing Claus Fritze, Lechler, Germany. Figure 1: structure of the APC Process Proven technologies for the reduction of NO x emissions, in addition to primary measurements, are either the... |
Beyond primary measures25 July 2022, Published under Cement NewsUnder tightening emission legislation, it may be time to consider new technologies and products to remain in compliance. Denmark-based Umicore offers a variety of catalysts for the removal of NO x , NH 3 , dioxins, CO and various volatile organic compounds (VOCs). Globally several cement plants are today operating with a Umicore catalyst. This article presents selected case stories from some of the company’s catalyst installations in cement plants. By Anders Rooma Nielsen, Umicore, Denmark. ... |
Sinoma Overseas Development completes SCR project27 May 2022, Published under Cement NewsSinoma Overseas Development’s selective catalytic reduction ( SCR) denitrification project with Lanfeng No2 cement production line in Sichuan, China, has been successfully completed. This ultra-low emission renovation project for air pollutants of cement kiln contracted by Sinoma Overseas passed the performance test before being transferred to the owner, with all indicators reaching Chinese A-level standards and outperforming the agreed in the contract. The project adop... |
Selecting the right SCR system29 June 2020, Published under Cement NewsHeavy dust loads and high temperatures are two of the most-challenging factors for DeNO x systems in the cement industry. In this article thyssenkrupp Industrial Solutions with its CemCat brand for SCR systems, explains the success story of its specialised high-dust SCR system to reduce operating costs and the risk of kiln stoppage. By thyssenkrupp Industrial Solutions (China) Co Ltd, China. Figure 1: for more than 14 years, CemCat has built high-dust SCR plants worldwide to help ... |
Lowering the temperature14 October 2019, Published under Cement NewsClinker production is a high-temperature combustion process that generates nitrogen oxides (NO x ), one of the most significant kiln emissions. To reduce these emissions, selective catalytic reduction (SCR) has been widely acknowledged as the best available technology. By Area Impianti SpA, Italy. The use of selective catalytic reduction helps reduce NO x emissions from cement production Among the NO x reduction techniques, selective catalytic reduction (SCR) is the best av... |
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... |
Semi-dust SCR at Mannersdorf28 September 2015, Published under Cement NewsThe 1.1Mta Lafarge Mannersdorf works in Austria is the country’s largest cement plant and a pioneer of environmental protection within the European cement industry. As part of these endevours, the world’s first semi-dust catalytic reduction (SCR) system was installed at the plant in spring 2012 by Scheuch of Austria. Over the past three years, the existing system has been gradually optimised and guarantees reliable compliance with NOx and NH3 emissions. By Scheuch, Austria. The semi-d... |
