A comparison of the energy intensity of traditional calcination and novel calcination-free Ca(OH)2 production processes. Herein, for the “Novel” process, the thermal energy – being in the form of low-grade waste heat – is excluded from the analysis.
| Energy consumption (kJ kg−1 Ca(OH)2) | Process | ||
|---|---|---|---|
| Traditional | Novel | ||
| Total thermal energy | Q T | 4000 | 677 150 |
| Total work | W T = WRO + WP | — | 2241 |
| Total energy | E T = QT + WT | 4000 | 679 391 |
| Total high-grade energy | E T − Qs,alt | 4000 | 2241 |
