Pulp Chemical Consumption with cooking chemical load of 5 value: a worked example

This worked example runs the pulp chemical consumption numbers for a tougher week than the baseline: cooking chemical load of 5 value instead of the typical 10 value. Estimate pulp chemical consumption for wood and paper manufacturing using production-ready inputs so teams can roll up the components into one defensible total.

The inputs for this scenario

  • Cooking chemical load (e.g. white liquor): 5 value (the input this scenario stresses; the baseline uses 10)
  • Bleaching chemical load (e.g. chlorine dioxide): 8 value (held at the documented default)
  • Additive load (e.g. sizing agent): 4 value (held at the documented default)
  • Auxiliary chemical load (e.g. defoamer): 2 value (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Total pulp chemical consumption = first pulp chemical consumption cost or load + second pulp chemical consumption cost or load + third pulp chemical consumption cost or load + fourth pulp chemical consumption cost or load.
  • Total pulp chemical consumption works out to 19 units at these inputs, and this is the headline figure for the scenario.
  • Element 1 works out to 5 units at these inputs.
  • Element 2 works out to 8 units at these inputs.
  • Element 3 + 4 works out to 6 units at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where cooking chemical load sits at 10 value and the headline result is 24 units, this scenario comes in 20.83% below the baseline at 19 units.
  • Use it when rolling up chemistry cost per tonne, comparing shifts or lines, or preparing effluent and load reporting. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Total pulp chemical consumption: 19 units (headline result)
  • Element 1: 5 units
  • Element 2: 8 units
  • Element 3 + 4: 6 units
