Carbon Savings Calculator
Carbon screening
Enter the reboiler duties of the columns you run today and read back what a dividing wall column takes off the bill each year — in your currency, on your energy prices, measured against your own refinery. Money and carbon side by side, priced on steam or on fuel gas, in ten currencies, with one click to a printable PDF.
Reboiler duty, two columns → one
The wall removes the remixing between the two columns — that recovered 19.2 MMkcal/h is 92,494 t CO₂e a year.
Carbon screening
What does the energy saving weigh in carbon?
Put in the reboiler duties you run today. See the CO₂e a dividing wall avoids each year, what that saving is worth, and how it measures against a whole refinery.
