Abstract

Cement industry is responsible for approximately 5% of global anthropogenic carbon dioxide emissions emitting nearly 900 kg of CO2 for every 1000 kg of cement produced. Effective control strategies to mitigate these emissions were discussed and a mathematical programming model able to suggest the best cost effective strategy was formulated. Control costs consisting of operating and retrofit costs along with the efficiency of control options are taken into account in the model. A representative case study from the cement industry was considered in order to illustrate the use of the model in giving optimal control strategies. The hazard control model was solved using commercial software called LP_SOLVE (Version 5.5) configured to apply the branch and bound algorithm. Efficiency improvement measures were the considered mitigation option and it was found to be effective options for reduction targets up to 18 %. Four efficiency improvement technologies were considered and a reduction of 18% amounting to almost 100,000 tonnes of emission was achieved with an increase of 14.3% and 9.1% in production and operating cost respectively. The findings of this study will help cement plant operators to reduce their emission level by implementing various retrofit options to suite intended targets and subsequently reducing environmental health risk.
