Cement production is an energy intensive industry Energy utilization in cement production accounts for 5060 of the total production costs Thermal energy accounts for about 2025 of the cement production cost The typical electrical energy consumption of a modern cement plant is about 110120 kWh per ton of cement

Fade out of wet cement production routes Cement can be manufactured through four different routes dry semidry semiwet and wet process The dry or wet state of its raw materials determines the use of the routes Wet processes consume more energy and are therefore expected to fade out stepwise until 2030 Wet cement

However the impact of cement industries is more important that other energy intensive industries because of the volume of cement production A recent study showed that the main driver for CO 2 emission reduction in the French context from 1990 to 2005 has been the reduction in cement production rather than the improvement in technology

Energy optimization in cement manufacturing Reprint from ABB Review 22007 Cement producers are large consumers of thermal and electrical energy which on a global level are only available at steadily increasing costs Efforts to reduce demands by using higher ef ciency equipment and substituting fuels and raw materials to lower production

The country is wellplaced to benefit from steadily rising demand in the medium and long term although producers will need to ensure a stable supply of inputs including energy Recent History Prior to the Arab Spring Egypts cement industry had been growing strongly Production increased from 30m tonnes in 2006 to 50m tonnes in 2010

The cement industry is one of the worlds largest industrial sources of CO2 emissions accounting for 18 Gty in 2005 ie more than 6 of global emissions from the use of fossil fuels Over the years the cement industry has substantially reduced emissions of CO2 per tonne of cement by improved energy

Aug 28 2017 The production of 1 m of concrete requires 2775 MJ of energy This energy comes mostly from oil burning which generates CO2 2775 MJ of energy is produced by 037 barrels of oil Saving concrete eg by adopting appropriate building solutions means therefore not only reducing fossil fuels consumption but also pollutant emissions

The cementmaking process benefits from steady production conditions which ensure both process efficiency and highquality cement Traditionally this has meant that most plants relied on coal as their fuel of choice because it burns consistently has high calorific value and is easy to handle compared to some other fuels

Progress so far has come in three main areas First more efficient cement kilns have made production less energyintensive This can improve further global average energy use per tonne of cement is still around 20 higher than production with current best available technology and practice

From a technology point of view grinding remains the biggest source of energy consumption in cement production While total electrical energy consumption for cement production is about 100 kWht of cement roughly two thirds are used for particle size reduction 31 32 Fig 5

Today electrical energy consumption in cement works makes up over 10 per cent of the total energy consumption with the energy costs being split almost equally between fuel and electricity In total the German cement industry used 960 million gigajoules of fuel in 2018 whilst electricity consumption was 378 terrawatt hours TWh
