METHOD & PROCESS PRINCIPLE
Beer stripping, rectification, hydroselection/purification, aldehyde concentration and fusel-oil side draws are heat-integrated and controlled by reflux and pressure profile.
ENA PROCESS UNITS
ENA Multi-Column Rectification
Separates ethanol from water and removes low-boiling heads, higher alcohols and other congeners to achieve neutral sensory and chemical quality.
MAIN EQUIPMENT & PACKAGE LIMITS
Beer column, rectifier, hydroselection/purification column, aldehyde/heads column, fusel decanter, reboilers, condensers, pumps and analyzers.
CRITICAL DESIGN INPUTS
Approved raw-material analysis, fermentable sugar or starch, contaminants, water quality, capacity, required alcohol grade, recovery target, fermentation basis, by-product route and utilities. Required ENA impurity limits and organoleptic target.
ENGINEERING DELIVERABLES
Design Basis, process calculations, PFD, P&ID, datasheets, equipment/instrument/line lists, layouts, control narratives, cause-and-effect, inspection plan, FAT/SAT and commissioning documents.
AUTOMATION, SAFETY & HSE
Hazardous-area classification, alarms/interlocks, relief and venting, CIP/cleaning safety where applicable, fire and gas interfaces, HAZOP actions, ESD philosophy and traceable quality release.
APPLICATIONS & PERFORMANCE BASIS
ENA for regulated beverage, cosmetic, pharmaceutical or industrial routes after grade-specific qualification.
