Global 2 emissions from cement production
clinker production data, cement production data may be used to estimate clinker production by taking into account the amounts and types of cement produced and their clinker con tents and including a correction for clinker imports and exports. Accounting for imports and exports of clinker is an important factor in the estimation of emissions from this source." In addition, the IPCC ...
Clinkering Process in Portland Cement Manufacturing
· In portland cement manufacturing, the raw materials are changed to clinker in the burning operation. Generally the rotary kiln is used for this purpose and involves many processes including pelletizing and nodulizing. This transformation is called clinkering and is analyzed as now generally practiced in cement making from the raw material to the resulting clinker.
CO2 Emissions Profile of the Cement Industry
Cement production also is a key source of CO2 emissions, due in part to the significant reliance on coal and petroleum coke to fuel the kilns for clinker production. Globally, CO2 emissions from cement production were estimated at 829 MMTCO2 in 2000 7, approximately % of global CO 2 emissions from fossil fuel combustion and cement production ...
