Alpacem Cement, dd – Comprehensive energy audit

CHALLENGE:

Increasing energy efficiency in a highly optimized energy-intensive technological process, which represents 3.0% of Slovenia’s final energy consumption (excluding energy consumption for transport) and ranks among the best cement plants in the world in terms of energy efficiency.

SOLUTION:

We conducted a comprehensive energy audit of the cement plant at the Anhovo location, where the client was helped at the beginning of the audit to evaluate the potential of the most intensive process, which is the clinker production kiln.

Based on our own measurements and analyses, we also identified 1.1 GWh of organizational potential that requires optimization of settings or upgrading of regulation.

We also provided the client with guidelines on the transition to a closed cooling system and the possibility of utilizing waste heat from secondary systems, taking into account the reciprocity between individual systems.

Despite highly optimized processes and constant variations in input parameters, an energy audit using targeted energy consumption monitoring methods on electrical consumers identified a potential of 1.8%. Based on these findings, guidelines were also given for upgrading the energy management system.

EMPHASIS:

The energy audit focused primarily on the operation of support systems, which resulted in proposals for increasing energy efficiency and utilizing waste heat, taking into account the interdependencies between systems.
