Cement Plant - an overview | ScienceDirect Topics

The mass and energy balances for the cement plant concepts with carbon capture were used furthermore to evaluate the key plant performances. The designs were optimized by performing a heat integration analysis (using pinch technique) for maximization of the overall energy efficiency (Smith, 2005).As an illustrative example, Figure 1 presents the hot and cold composite curves for the calcium ...

Cement accounts for at least 5 percent of anthropogenic emissions of greenhouse gases, and, according to some estimates, this share may be even higher. At the same time, energy-related expenses in the cement sector, mostly on fossil fuels and electricity, account for 30 to 40 percent of the industry's cash costs. While current energy
