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 .
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
- Cooling water
- Process water
- Boiler feed water
- Inert gas
Waste Disposal Costs
These are defined as the cost of waste treatment to protect the environment .
Fixed Cost of Production
Estimating Fixed Production Costs
These are the costs attributed to the personnel required to operate the process plant .
Part of these costs are associated with labor and materials necessary to maintain plant production .
