Ciments d'Enfidha, a member of Spain’s Grupo Cementos Portland Valderrivas, runs the Enfidha cement plant in Tunisia. With partner Handasa Solutions et Services, Denka® filter plates (then supplied under the Enersol name) were fitted at the last circuit breakers ahead of the electric motors in the kiln workshop (P4), to absorb conducted electrical noise and lower consumption.
How it was measured
- Without plates: 9 November – 6 December 2021
- With plates: 2 – 28 April 2022
- Two calculation methods: motor speed and raw-meal feed rate
Results
- 7.41% average saving by motor speed (6.66–8.16%)
- 6.54% average saving by raw-meal feed rate (5.90–7.17%)
- 167–187 MWh saved per month in the kiln workshop
Confirmed in a signed attestation by the plant’s Head of Electrical Service, 13 September 2022.
