TECHNOLOGY

Process architecture
with recovery at its core.

A connected process chain from grain preparation through fermentation, ENA purification and DDGS recovery, supported by integrated utilities, controls and environmental systems.

ARANYA INDUSTRIAL PROJECT CHHATTISGARH · INDIA
Core process

Grain → ethanol → recovery.

ARANYA is conceived as an integrated process rather than a collection of independent equipment packages. Material, energy, water and process-control interfaces are considered across the complete chain.

A

Preparation

Receiving, weighing, cleaning, destoning, magnetic separation, milling and slurry preparation establish a controlled feed stream.

B

Conversion

Jet cooking/liquefaction, saccharification, enzyme dosing and controlled yeast propagation convert prepared grain into a fermentable substrate.

C

Fermentation

Controlled fermentation with cooling, monitoring and process hygiene provides the biological conversion stage.

D

Distillation

Distillation, rectification and associated heat-exchange systems separate and polish the alcohol stream toward the planned ENA quality basis.

E

DDGS recovery

Decanter separation, thin-stillage concentration and drying are integrated to recover a commercial co-product stream.

F

Utilities & control

Steam, condensate, cooling, RO/DM, CIP, instrumentation and PLC/SCADA integration support stable and measurable operation.

Process architecture

Designed as one connected system.

♨

Steam & energy

A rice-husk/biomass boiler concept supports process steam requirements, with detailed heat and fuel balance to be confirmed during engineering.

↻

Water recovery

Raw-water treatment, RO/DM, condensate recovery and process-water reuse are incorporated into the development basis.

◎

Environmental control

MEE/ZLD and associated treatment systems form the current environmental design concept, subject to statutory and detailed engineering confirmation.

⌁

Cooling

Fermentation and process cooling systems are integrated with the utility network to support stable operating conditions.

⌘

Automation

PLC/SCADA, instrumentation and process measurement are intended to provide visibility over critical operating parameters.

✓

Quality control

Laboratory and online monitoring are intended to support feedstock, fermentation, distillation and final product quality control.

Control philosophy

Measure first. Optimise continuously.

ARANYA's engineering basis is intended to support instrumentation, laboratory QC and automated process control so that yield, energy, water and product quality can be monitored rather than assumed.

Engineering status: The technology described on this website represents the current development basis. Final equipment specifications, process guarantees, heat and mass balances, water balance and control philosophy will be established through detailed engineering and qualified vendor quotations before final project investment decisions.
