This JI project will be implemented at Podilsky Cement in Kamyanets-Podilsky, Ukraine. Global Carbon developed all documentation for this project including an approach to set the baseline and estimate the emissions reductions. This project is the first JI project that has been registered at the UNFCCC and the first JI project in the cement industry.
The Podilsky Cement factory was constructed in the 1970s and is one of the biggest cement plants in Ukraine. The envisaged project will decrease the emissions of fossil fuel combustion by changing the technology of cement production from a wet production process to a dry production process.
Wet cement production technology is the conventional technology of cement production in Ukraine. During raw material preparation stage limestone, clay and additives are crushed and mixed in the raw mill. In the case of wet cement technology water is added to the raw mill together with the raw materials in order to produce slurry. The slurry is further homogenized and fed into the rotary kiln.
At the point of the kiln inlet, at the drying zone, water is evaporated from the slurry, and raw materials are moved further into the kiln to be calcined and burnt into clinker. Evaporation of the wet slurry consumes significant amounts of energy. At present the average energy consumption at Podilsky Cement over the years 2003, 2004, and 2005 is 6,771 MJ per tonne of clinker produced (1618 kcal/kg).
In case of conventional dry cement production technology, the raw materials required are of low moisture content. Water is not added in the preparation of the mixture of raw materials (being called the raw meal in case of dry production scheme).
Therefore water evaporation from the raw meal is not required. This significantly reduces the level of energy consumption of a dry cement kiln compared to a wet one, and therefore reduces the CO2 emissions from fuel combustion.
The expected energy consumption of the dry cement production system at Podilsky Cement will be approximately 3,180 MJ per tonne of clinker produced (760 kcal/kg). This constitutes a reduction of 53% in energy consumption!
Emission Reductions
A total of 3,023,403 tonnes CO2 will be reduced until the year 2012.
JI Project status
The JI Project - Podilsky Cement was the first ever registered project under Joint Implementation Supervisory Committee of the UNFCCC on 27 March 2007. The Project Design Document of the project could be found at the JI UNFCCC website here.
