Waste heat utilisation of Croatian cement industry accounting Total Site demands

The cement industry sector as an energy intensive industrial sector, where energy cost represents approximately 40% of the total production cost per one ton of cement, and one of the highest greenhouse gases - GHG emitting industrial sectors, accounts for around 5% of global anthropogenic GHG emissions as reported (Mikulčić et al, 2015). Considering that, the cement is the most widely used material for construction needs, this paper analyses the potential of energy efficiency improvement of the cement production for a particular cement plant in Croatia. The heat recovery potential was determined and an amount of waste heat available for utilisation accounting site wide demands are identified with use of Process Integration technique. The results show huge potential for energy saving of cement production. Different scenarios for utilization of low potential heat are proposed accounting different site demands and energy prices. Implementation of paper results helps to the cement plant’s profitability and reduces environmental impact of the cement industry.
