CO 2 emission for clinker, OPC and PPC | Download

This is crucial since the production of OPC requires a lot of energy owing to preprocessing, and as a result, 0.85 to 0.92 tons of CO 2 are released for every ton of OPC produced [3].

Cement emissions intensity has remained relatively stable since 2018, at just under 0.6 t CO 2 per tonne of cement produced, following several years of modest increase largely due to an increasing clinker-to-cement ratio in China. To get on track with the NZE Scenario, emissions must fall by an average of 3% annually through to 2030.

Clinker-Cembureau

Clinker. Clinker is the backbone of cement production. It is essentially a mix of limestone and minerals that have been heated in a kiln and have been transformed by this heat. When limestone is converted to clinker, CO 2 is released (also known as process emissions). A substantial amount of heat is needed to start and sustain the chemical

Using these cements significantly cuts CO2 emissions during cement production, as a 1% reduction in clinker reduces CO2 emissions by approximately 8.5 kg/ton [13].

Energy Use – Cement

In total Australian cement producers consumed around 19.7 PJ of thermal energy, down 3 per cent year-on-year and down 30 per cent since 2010-11. Of this 57 per cent came from coal, 24 per cent from natural gas, 1 per cent from diesel oil and other fuels. The remaining 18 per cent was derived from alternative fuels such as wood waste, solvents

CEMENT RAW MATERIALS

Cement plants are highly capital intensive. The construction of new plant costs about £10 million for each 100 000 tonnes per year of cement capacity. Large modern plants can, therefore, cost over £100 million. Ongoing capital investment at individual plants can also typically amount to several million pounds a year.

Study of Energy Use and CO2 Emissions in the Manufacturing of Clinker

The gate-to-gate system boundary condition is considered. The energy use for clinker is found to be 3990 and 3626 MJ/ton for case studies 1 and 2, respectively. The associated CO2 emissions for clinker are 849 and 868 kg CO2/ton. The energy use for OPC is 4015 and 3821 MJ/ton for case studies 1 and 2, respectively.

3.1 CO2 Cement Production-IGES

Carbon dioxide is emitted as a by-product of clinker production, an intermediate product in cement manufacture, in which calcium carbonate (CaCO3) is calcinated and converted to lime (CaO), the primary component of cement. CO2 is also emitted during cement production by fossil fuel combustion. However, the CO2 from fossil fuels is specifically
