The kraft process can use a wider range of fiber sources than most other pulping processes.
bleach plant and then calculating the lime required to make that quantity of white liquor. The quantity of lime mud solids is determined next so that the underflow from the white liquor clarifier can be calculated. The calculations use the molecular weights of the compounds to make the conversions, for example calcium oxide to calcium carbonate.

The electric power consumption of an efficient plant is around 20 kWh per tonne of lime. This additional input is the equivalent of around 20 kg CO 2 per ton if the electricity is coal-generated. Thus, total emission may be around 1 tonne of CO 2 for every tonne of lime even in efficient industrial plants.
