KOCTECH develops integrated ethyl alcohol plants covering raw-material preparation, fermentation, distillation, rectification, purification, dehydration, product polishing and storage. The final process configuration is selected according to feedstock, required alcohol grade and applicable regulatory requirements.
High-purity neutral ethyl alcohol is produced through controlled fermentation, multi-pressure distillation, rectification, hydroselection/purification, fusel-oil separation and final polishing. The design basis is established for the intended food, beverage, cosmetic, pharmaceutical or industrial grade and destination-country regulation.
Suma is produced from approved grape-origin agricultural feedstocks. The system includes grape must preparation, controlled fermentation, wine/beer distillation, separation of heads and tails, fusel-oil management and product stabilization while preserving the required origin and quality characteristics.
Bioethanol production combines starch- or sugar-based feed preparation, enzymatic conversion where required, fermentation, distillation, rectification and molecular-sieve dehydration. Product specification, denaturing system and gasoline-blending interface are configured for the applicable fuel standard.
Feed receiving and preparation; fermentation vessels and beer well; analyzer/beer column; rectification and hydroselection columns; fusel-oil separation; condensers and reboilers; molecular-sieve dehydration; product polishing, denaturing, storage and loading.
Design Basis, feed and product specifications, heat and material balance, PFD, P&ID, equipment datasheets, column hydraulic design, fermentation controls, utility balance, 3D model, automation philosophy, hazardous-area study and performance-test procedure.
Temperature, pressure, flow, level, fermentation parameters, alcohol strength and critical quality indicators are monitored through the plant control system. Batch traceability, recipe management, interlocks, CIP philosophy and laboratory interfaces are defined according to the selected product grade.
Steam and condensate, cooling water, process water, instrument air, CIP, stillage handling, wastewater treatment, CO₂ recovery options, heat integration and energy-recovery measures are integrated into the overall plant design.
Neutral alcohol for approved beverage, food, cosmetic, pharmaceutical and industrial uses; grape-origin Suma; anhydrous or hydrous Bioethanol for regulated fuel and industrial applications.
Food-contact and hygienic-design requirements where applicable; ASME, API, EN, DIN, IEC, ATEX and destination-country regulations; applicable EN 15376, ASTM D4806 or national fuel-ethanol specifications for Bioethanol. Final standards are confirmed in the approved Design Basis.
Each process section is engineered from the approved feed characterization, required product specification, site utilities and contractual battery limits. Select a unit for its process principle, equipment, controls, deliverables and applicable standards.
Feed Preparation & ConversionMilling, liquefaction, saccharification or sugar-feed conditioning provide a controlled fermentable substrate for the selected raw material.OPEN UNIT PAGE →
FermentationYeast propagation, fermentation temperature, pH, nutrients and contamination control determine alcohol yield and congener formation.OPEN UNIT PAGE →
Ethyl Alcohol Rectification UnitRectification, hydroselection and impurity side-draw sections purify crude alcohol and control aldehydes, methanol and higher alcohols for ENA, Suma or technical-alcohol duty.OPEN UNIT PAGE →
Molecular-Sieve DehydrationPressure-swing adsorption removes water beyond the azeotrope to produce anhydrous bioethanol for fuel or technical applications.OPEN UNIT PAGE →
