The Kraft pulp input per ton of CNC is different to produce CNC61 and CNC64 due to significant differences in processes yield (70 vs. 30% respectively). However, the amount of consumed acid is approximately the same. This is because acid/pulp ratio for CNC61 is much demand reflect the differences in process parameters for CNC61 and CNC64 (more electricity is used in grinding pulp for CNC64 as pulp input is 2.5 times higher, and more electricity is consumed for UF for CNC64 as more water is required to be pumped). However, CNC drying accounts for nearly 99% of the total electricity consumption in both cases and equals 182 and 245 GJ/day for CNC61 and CNC64, respectively.
