Abstract

Cement production is an energy intensive industrial process that requires heat to be supplied at high temperature levels under the constraints of gas-solid heat exchange phenomena and the kinetics of chemical reactions. In this paper, the use of Pinch Analysis and Process Integration techniques to optimize the energy efficiency of the cement production will be explored. The aim is to use process modeling to characterize cooling and heating ...
