Variable Cost of Production

Estimating Variable Production Costs

Raw Materials Cost

These are the costs of chemical feed stocks required by the process. Feed stocks flow rates are obtained from PFD [6].

Utilities Cost

These are the costs of the various utilities streams required by the process. The flowrates for the utilities streams are located on the PFD. This includes:

  • Fuel gas, oil, or coal
  • Electric power
  • Steam
  • Cooling water
  • Process water
  • Boiler feed water
  • Air
  • Inert gas
  • Refrigeration
