🍬→🥃 Sugar to Ethanol Calculator

Mode 1 (General Chemistry). Enter cane crushed (C, MT), sugar recovery fraction (S), and molasses fraction (M). Toggle advanced constants if needed.

MT
Metric tons processed.
As fraction (0–1) or percent (0–100).
As fraction (0–1) or percent (0–100).
💾 Autosave: On
Advanced constants adjustable
kg EtOH / kg sugar
Default 0.48 (≈90% of 0.538 theoretical).
kg/L
Default 0.789 kg/L.
L per MT molasses
Typical 220–280; adjust using TRS if known.
%
Set 1–3% for fuel‑grade (≥99.5% v/v).
Formula: E(L) = C×1000×S×(ηₛ/ρₑ) + C×M×Yₘₒₗ. With defaults: ≈ C×(607.1×S) + C×(250×M).

Python function

def ethanol_liters(cane_MT, sugar_frac, molasses_frac, eta_s=0.48, rho_e=0.789, Y_mol=250):
    ethanol_from_sugar = cane_MT * 1000 * sugar_frac * (eta_s / rho_e)
    ethanol_from_molasses = cane_MT * molasses_frac * Y_mol
    return ethanol_from_sugar + ethanol_from_molasses

Notes: Set S=0 for molasses‑only; set M=0 for crystal‑sugar diversion only. If you know molasses TRS, refine Yₘₒₗ ≈ (kg fermentables/MT) × ηₛ / ρₑ.

Sugarcane to Ethanol Calculator – Free Online Tool for Mills & Researchers : VS

Meta Description (SEO, 150–160 chars)

“Calculate ethanol yield from sugarcane and molasses instantly. Plug in cane crushed, sugar recovery, and molasses % to estimate liters of ethanol.”

Intro Paragraph

Ethanol production is at the heart of sugarcane processing, whether for fuel blending, beverage alcohol, or industrial use. To make planning easier, we built this Sugar → Ethanol Calculator. It lets you estimate how many liters of anhydrous ethanol you can obtain from:

  • Crystal sugar diverted to fermentation
  • Molasses generated during sugar production

This tool is free, transparent, and adjustable. You can input your mill’s real numbers (cane crushed, sugar % recovery, molasses %), and refine advanced constants like ethanol yield, density, or distillation losses.

How the Calculator Works

The calculator is based on standard chemical assumptions:

  • ηₛ (sugar→ethanol yield): 0.48 kg ethanol per kg sugar (≈90% of theoretical).
  • ρₑ (ethanol density @20 °C): 0.789 kg/L.
  • Yₘₒₗ (molasses→ethanol yield): 250 L per MT molasses (adjustable with TRS data).
  • Formula: Ethanol (L)=C×1000×S×ηsρe+C×M×Ymol\text{Ethanol (L)} = C \times 1000 \times S \times \frac{ηₛ}{ρₑ} + C \times M \times Yₘₒₗ where C = cane crushed (MT), S = sugar fraction, M = molasses fraction.

With default values, this simplifies to: Ethanol (L)≈C×(607.1×S)+C×(250×M)\text{Ethanol (L)} ≈ C × (607.1 × S) + C × (250 × M)

Why Use This Tool?

  • Quick calculations for feasibility and project reports
  • Transparency – every constant can be adjusted
  • Practical defaults (based on real industrial yields)
  • Educational value for students & researchers
  • No signup, no cost – runs directly in your browser

Example Scenarios

  • Case A (Mixed): 10,000 MT cane, S = 0.10, M = 0.04 → ≈ 707,100 L ethanol
  • Case B (Molasses only): 10,000 MT cane, S = 0, M = 0.045 → ≈ 112,500 L ethanol

FAQ – Sugar to Ethanol Calculator

Q1. What inputs do I need?
You just need cane crushed (MT), sugar % recovery, and molasses % on cane.

Q2. Can I use percentages instead of fractions?
Yes, the tool accepts both (e.g., 10% = 0.10).

Q3. Is this suitable for molasses-only ethanol plants?
Yes – just set sugar recovery (S) to zero.

Q4. Can I adjust for distillation losses?
Yes – typically 1–3% loss for fuel-grade ethanol. Use the advanced settings.

Q5. Is this calculator valid for all sugarcane varieties?
It gives a good baseline estimate, but exact values depend on TRS, fermentation efficiency, and plant design.

Q6. Can I download or share results?
Yes – the widget allows printing and generating a shareable URL with pre-filled values.

Q7. Is this tool free?
Absolutely. It’s open and free to use on ethanolnews.in.
