    Energy auditing in cement industry A case study

    The production of cement is an energy-intensive process. Typically, energy consumption accounts for 20-40 of production costs. In 2008, the U.S. cement industry spent about 1.7 billion to purchase energy around 0.75 billion of this was for electricity and 0.9 billion for fuels..Jun 09, 2020 In a cement plant using our decarbonation reactor, the O 2 CO 2 gas mixture could therefore be used as oxy-fuel in the high-temperature kiln to lower energy consumption and NO x emissions. Among other benefits of oxygen enrichment, 1 commercial-scale experiment using 30 to 35 oxygen enrichment resulted in a 25 to 50 increase in cement kiln ...
