Ultra Pure Neutral Spirit (ENA) Technologies

What is Extra Neutral Alcohol (ENA)?

Ultra Pure Extra Neutral Alcohol (ENA) is a highly rectified ethanol (≥96% v/v alcohol by volume) that is free from objectionable odors, flavors, and color. It is produced from fermented feedstocks such as molasses, sugarcane juice, or grains, tubers like cassava and potato which undergoes multiple stages of distillation, rectification, and polishing to achieve high purity levels.

Applications

• Alcoholic beverages (vodka, gin, liquors)
• Pharmaceutical-grade antiseptics and tonics
• Cosmetic formulations (perfumes, deodorants)
• Food-grade flavor extracts and essences

IBHA ENA Plant – Key Process Modules

Our ENA systems are designed for continuous operation, built on proven process blocks and modular skid-based construction to allow fast installation, commissioning, and expansion.

1. Fermentation

• Continuous or batch fermentation systems

• Pre-clarification before distillation

2. Primary Distillation

• Multi-pressure distillation columns (analyzer, degasser, pre-rectifier)
• Removal of fusel oils, aldehydes, and other volatiles
• Efficient energy integration through thermal vapor recompression (TVR)

3. Rectification

• High-precision rectifier columns for ethanol concentration up to 96% v/v
• Internal structured or bubble cap trays for optimum separation
• Integrated fusel oil decanters

4. Concentration & Purification
