Equipment manufacturing
Our Boluo manufacturing base connects equipment design with fabrication and inspection. Automated cutting, welding equipment, tube-sheet production and vessel assembly support columns, heat exchangers and pressure equipment. Materials, welds, dimensional checks and inspection records follow the approved project requirements.
Explore ↗
Quality assurance & traceability
Control the documents, verify the materials, inspect the work and retain the records. These are the foundations of CNE’s documented project quality approach.
Explore ↗
Installation, commissioning & training
Move from completed construction to an accepted operating plant through documented checks, coordinated trial runs and trained operators.
Explore ↗
Engineering documents & project interfaces
A process package becomes buildable when drawings, equipment data, control requirements and responsibilities agree. CNE’s service documentation describes the deliverables that connect these disciplines.
Explore ↗Built around your project.
Fuel markets and food-grade alcohol demand different finishing systems. Start with your product specification.
Fuel ethanol plants
Integrated ethanol production systems for fuel markets, with fermentation, heat-integrated distillation and molecular-sieve dehydration engineered as a coordinated process.
Explore ↗
Food-grade ethanol & ENA ethanol plants
Precision separation for neutral alcohol applications. The process is selected around impurity control, sensory quality and the buyer’s complete product specification.
Explore ↗
Medical ethanol plants
Hydrous and anhydrous ethanol routes for medical applications. We coordinate refining, dehydration, product-contact materials and sampling around the agreed pharmacopoeial or purchaser specification. The Indonesia upgrade combines a 50,000 t/y ENA scope with a 30,000 t/y medical anhydrous scope; the product split defines the process balance.

Different raw materials need different front ends. Choose a route below to see the preparation steps, engineering priorities and data needed for a useful proposal.
Explore ↗02 / Ferment
Feed preparation, liquefaction & fermentation
The front end sets the conditions for downstream separation. Our cassava front end integrates storage, milling, liquefaction, saccharification and controlled fermentation.
Explore ↗03 / Distil
Multi-effect distillation
Separate impurities with purpose. Reuse heat across pressure levels. Select the column arrangement for the product mix and the real feed composition.
Explore ↗04 / Refine
Food-grade ethanol & ENA ethanol plants
Precision separation for neutral alcohol applications. The process is selected around impurity control, sensory quality and the buyer’s complete product specification.
Explore ↗05 / Dehydrate
Molecular-sieve dehydration
Continuous water removal through alternating adsorption and regeneration. A finishing stage for anhydrous ethanol production.
Explore ↗06 / Stillage & co-products
Stillage evaporation & DDGS systems
Coordinate solids separation, thin-stillage evaporation, syrup blending and drying around a defined co-product specification. DDGS is a process system, not a general accessory; a molasses stillage route requires a different residue strategy.
