Pulp Chemical Consumption with cooking chemical load of 25 value: a worked example

What does the result look like when cooking chemical load reaches 25 value? The full calculation is worked below with real intermediate numbers. Use it when pulp chemical consumption in wood and paper manufacturing needs a clean total of wood and paper manufacturing contributors for a quote or a review.

The inputs for this scenario

  • Cooking chemical load (e.g. white liquor): 25 value (raised for this scenario; the documented default is 10)
  • Bleaching chemical load (e.g. chlorine dioxide): 8 value (unchanged)
  • Additive load (e.g. sizing agent): 4 value (unchanged)
  • Auxiliary chemical load (e.g. defoamer): 2 value (unchanged)

Working through the calculation

  • Applying the documented formula (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) to the inputs above produces each figure below.
  • At this operating point the engine returns 39 units for total pulp chemical consumption, the number this scenario is built around.
  • At this operating point the engine returns 25 units for element 1.
  • At this operating point the engine returns 8 units for element 2.
  • At this operating point the engine returns 6 units for element 3 + 4.

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 62.5% above the baseline at 39 units.
  • A figure at this level is achievable when cooking chemical load is genuinely sustained, not just peaked for a shift. It is a straight sum in one unit; if your loads are in different units (kg/t vs cost vs active-basis vs as-delivered) you must normalize them first or the total is meaningless.

Results at a glance

  • Total pulp chemical consumption: 39 units (headline result)
  • Element 1: 25 units
  • Element 2: 8 units
  • Element 3 + 4: 6 units
