ETHANOL RECOVERY SYSTEM

Traditional ethanol scrubbing methods consume high amounts of water and continously recycle recovered  ethanol (~ 4% v/v in scrubber bottoms) to be lost (vented) in upstream processes. Using a Haffmans Ethanol Recovery System - ERS, ethanol, water vapor  and potential heat entrained in the fermentation gas is recovered more efficiently. 

BENEFITS

• Low ROI: as low as 1 year
• Water savings:  up to 80% reduced water consumption
• High ethanol content: up to 15% vol/vol in scrubber bottom
• Retrofittable: Easy integration for quick start-up, low down time
• Potential heat recovery : Preheat utility streams
• Low pressure drop: as low as 8 inch (200 mm) WC
