ETHANOL DISTILLATION AND VINASSE CONCENTRATION
Ecovin and Ecovin JL combine innovation, energy efficiency and sustainability to reduce operating costs, optimize production processes and add value to sugarcane, corn and second-generation (E2G) ethanol production.
ECOVIN® VINASSE CONCENTRATION EVAPORATOR
The Ecovin is a vinasse concentration evaporator featuring Citrotec's exclusive Descending Turbulent Mist Technology, delivering outstanding thermal performance, low energy consumption and exceptional operational reliability.
In sugarcane ethanol production, the system significantly reduces vinasse volume, making transportation, storage and application as an organic liquid fertilizer much more efficient.
For corn ethanol plants, Ecovin concentrates the vinasse and incorporates it into DDG, enabling a closed-loop operation with no need to dispose of vinasse in the field.
Key Benefits of Ecovin®
• Reduces vinasse volume by up to 10 times;
• Low energy consumption;
• Fully automated operation with simple process control;
• Equipment manufactured entirely in stainless steel;
• Recovery and reuse of water extracted from vinasse for industrial and agricultural applications;
• Production of organic liquid fertilizer (sugarcane ethanol) or incorporation of vinasse into DDG (corn ethanol);
• Lower transportation, storage and vinasse handling costs;
• A solution designed to meet today's demands for operational efficiency and sustainability.
SECOND-GENERATION ECOVIN JL®: ETHANOL PRODUCTION WITH CONCENTRATED VINASSE
Developed by Citrotec® in partnership with ETECH, this system integrates hydrated ethanol distillation with the Ecovin JL Vinasse Concentration System, delivering outstanding energy efficiency and the production of high-quality ethanol.
The solution combines distillation columns, a reboiler, an evaporative condenser, a molecular sieve unit for anhydrous ethanol production, and the vinasse concentration system, including evaporator vessels, preheaters, reheaters, regenerative heaters, as well as all equipment, valves, instrumentation, and control systems required for fully integrated operation.
Designed, manufactured, and installed by Citrotec, the equipment complies with the stringent ISO 9001 quality standards and the main national and international codes and standards, including NR-13, ASME, ANSI, ASTM, API, AWWA, ABNT, and NBR 6123.
The Second-Generation Ecovin JL was developed to meet the demands of modern ethanol plants by integrating ethanol distillation and vinasse concentration into a single, highly energy-efficient process.
Utilizing Citrotec's exclusive Descending Turbulent Mist Technology, the system is fully integrated with the distillation columns, enabling ethanol production with vinasse already concentrated and without additional steam consumption, significantly reducing operating costs while maximizing the plant's energy efficiency.
For second-generation ethanol (E2G) facilities, the technology provides a significant competitive advantage by maximizing the utilization of available biomass, optimizing the plant's thermal balance, and making production more sustainable and efficient.
Key Benefits of Ecovin JL®
• Ethanol production with vinasse already concentrated, without additional steam consumption;
• Exclusive Descending Turbulent Mist Technology for outstanding thermal efficiency;
• Reduced vinasse volume and lower transportation and handling costs;
• Recovery and reuse of water extracted from vinasse in industrial processes;
• Fully automated operation with simple process control;
• Equipment manufactured entirely in stainless steel;
• Suitable for both new installations and retrofit projects.
