Improving SNCR performance21 December 2016, Published under Cement NewsIn recent years the reduction of nitrogen oxide (NOx) emissions in kiln lines has been an important topic which is expected to further gain prominence as central European emission limits are set to reduce to 200mg/Nm³ at the start of 2019. NH3 slip emission will also be limited to 30mg/Nm³. To meet these new limits, current SNCR technology will need to be reconsidered as a realistic NOx reduction degree is between 50-75 per cent depending on the kiln line design.

From flue gas to green growth02 April 2012, Published under Cement NewsWhile cement producers such as Lafarge have made the commitment to significantly reduce their CO2 emissions, if higher reductions are to be obtained, the industry must find new, non-traditional ways of cutting back levels. The Lafarge Research Center has investigated the conversion of flue gas CO2 into micro-algae biomass. Figure 1: the PBR used in the trial is composed of five ranks of glass tubes. The photograph shows one side of the PBR with 15 loops identified for each of the fiv... |
