Can You Provide a Cost Calculation for My Factory?
Direct Answer
Direct Answer Yes, but it has to be calculated on your actual data. Without real figures, any statement that switching saves a given percentage is just sales language.
Six inputs we need from you
- Purchase price and per-tonne consumption of the hydrosulfite you use now (g/L or % owf, either is fine)
- Purchase price and per-tonne consumption of caustic soda
- Liquor ratio and machine type (overflow, winch, air-flow, continuous)
- Process temperature and time
- Daily or monthly output
- Target performance figures (fastness rating, brightness, stripping efficiency)
Four outputs we return
| Output | What it covers |
|---|---|
| Reducing-agent cost per tonne | Current route against the alternative |
| Alkali cost | Thiourea dioxide usually needs more alkali, so this line cannot be left out |
| Total chemical cost per tonne | Reducing agent, alkali and auxiliaries |
| Sensitivity analysis | Effect of unit price, substitution ratio and output volume on the conclusion |
Two cautions
- Do not use price per kilogram as the comparison basis; it is the most common source of a wrong decision
- Beyond the chemicals themselves, include changes in warehousing, freight and effluent treatment
Bottom line
The calculation can be done, provided it uses your real prices and consumption rather than industry averages.
