  • Utilization of lime-dried sludge for eco-cement clinker production: effects of different feeding points

    Co-processing lime-dried sludge (LDS) in cement kilns is an appropriate technique to solve the problem of LDS disposal and promote the sustainable development for cement industry. However, there were limited studies that investigated the effects of feeding points on product quality and cement kiln emissions. In this study, simulated experiments were conducted by dividing the feeding points ...

  • End-of-life Tires as an Alternative Fuel (TDF) in Cement Kilns: Now Easier than Ever!

    End-of-life tires are a challenging type of waste since they are difficult to shred and are expensive to treat and get rid of. However, tire derived fuel TDF is an extremely good alternative to the traditional fuels used in cement kilns, like oil, coal, and petroleum coke. The following blog presents a solution and explains how TDF can be used for heating cement kilns. ...

  • Holcim Ste. Genevieve Cement Plant - Case Study

    Big and beautiful The new cement manufacturing facility of Holcim (US) at Ste. Genevieve with a production capacity of four million tonnes per year went on stream mid-2009 and is one of the most environmentally-efficient cement plants in the Holcim Group. It is 40 percent more energy-efficient than the Holcim (US) plants that were closed in 2009 and emits 10 to 25 percent less ...

  • Global solution: Gas and particulate analysis in Cement industry

    Cement plants are increasingly required to install continuous emission monitoring systems (CEMS). While these represent a significant financial outlay, a range of other factors also need to be considered when selecting a suitable CEMS. To the inexperienced, selecting a suitable CEM can mistakenly be considered as simply ensuring that the applicable national regulations (eg MACT in the USA, ...

  • Controlling Stack Emissions in the Wood Products Industry & Wood Fired Boilers

    Electrostatic precipitation has been a reliable technology since the early 1900's. Originally developed to abate serious smoke nuisances, the manufacturers of zinc, copper, and lead quickly found electric gas cleaning a cost efficient way to recover valuable product carried out of the stacks from furnace operations. Today electrostatic precipitators are found mainly on large power plants, cement ...

  • Comparative performance of cement kiln dust and activated carbon in removal of cadmium from aqueous solutions

    This study compared the performance of cement kiln dust (CKD) as industrial byproduct and commercially activated carbon (AC) as adsorbent derived from agricultural waste for the removal of cadmium (Cd2+) from aqueous solutions. CKD and AC were characterized by Fourier transform infrared (FTIR) and scanning electron microscopy (SEM) and surface areas demonstrate the differences of ...

  • Global growth in CO2 emissions almost stalled in 2014

    In 2014, the growth in global CO2 emissions from fossil fuel use and cement production slowed down to only 0.5% compared to 2013, while the world’s economy grew by 3%, showing a partial decoupling of CO2 emissions and economic growth. China and the United States increased their emissions by 0.9%. In the European Union, CO2 emissions decreased by an ...

  • EPA Settles Cement Air Pollution Case

    EPA recently settled a major pollution case with a cement producer on pollution controls that will reduce harmful emissions of nitrogen oxides. Nitrogen oxides are pollutants that can lead to illnesses such as asthma and other respiratory conditions. Nitrogen oxides contribute to the formation of ground-level ozone as well as particle pollution. EPA Regional Administrator, Judith A. Enck ...

  • Selenium recovery from kiln powder of cement manufacturing by chemical leaching and bioreduction

    A novel process by using chemical leaching followed by bacterial reductive precipitation was proposed for selenium recovery from kiln powder as a byproduct of cement manufacturing. The kiln powder at a slurry concentration of 10 w/v% with 0.25 M Na2CO3 at 28°C produced wastewater containing about 30 mg-Se/L selenium. The wastewater was diluted four-fold and adjusted to pH 8.0 as ...

  • Clear-span Geodesic Dome for TXI Riverside Cement Plant, Oro Grande, California case study

    The TXI Riverside cement plant, located in the desert town of Oro Grande, California, is a terrific example of state-of-the-art cement plant design. It is also significant for several reasons. The plant is located upon the state-protected historical site of two old lime kilns dating back to the 1800s. It sits along historic Route 66, and very near to interstate highway 15 about 75 miles east of ...

  • Martinsburg Plant, Washington D.C. – Massive upgrade and expansion case study

    The Martinsburg plant is unusual in a number of ways. Located on the outskirts of Martinsburg the plant has a strong relationship with the local community. When other facilities were closing their doors or postponing expansion projects, the Martinsburg cement plant invested over US$500 million in a massive upgrade and expansion that brought capacity up to 1.8 million t of cement. Although cement ...
