| Abstract: | The evaluation of energy consumption and energy saving of the carbonation nanometer calcium carbonate production process were analyzed. The waste heat resource of a nanometer calcium carbonate production plant was investigated, and a cascade utilization scheme of waste heat was proposed. The medium and high temperature waste heat was used in lithium bromide refrigeration unit to replace part of the original electric refrigeration units, and the low temperature waste heat was used to preheat the process water, slurry and dry air. Results showed that the waste heat utilization scheme can obtain good energy saving and improve the system efficiency. |
| Keywords: | nano-calcium carbonate carbonization method waste heat cascade utilization energy saving & benefit improvement |
