Evaporation System with high energy efficiency!
O GRATT Evaporation System is a high-efficiency thermal solution developed for vinasse concentration and recovery of soluble solids in industrial processes, with strong application in corn ethanol plants.
With the accelerated growth of the corn ethanol sector in Brazil, driven by the abundance of raw materials and the demand for more sustainable energy sources, it is essential to adopt technologies that increase production efficiency and reduce operational costs.
In this scenario, GRATT positions itself as a strategic supplier of industrial evaporation systems, delivering robust, efficient solutions adapted to the reality of plants.
How does it work?
The GRATT Evaporation System operates with multiple vacuum effects, using upward flow and saturated steam at low pressure as a source of thermal energy.
Main operational characteristics:
- Vacuum operation, reducing boiling temperature
- Use of saturated steam at low pressure (≈ 1.5 bar)
- Multi-effect system for greater energy efficiency
- Upward flow that improves thermal exchange
The system has a tubular beam calender designed to:
- Uniform steam distribution
- Efficient condensate routing
- Removal of incondensable gases
This set guarantees high evaporation rates and operational stability.
An important difference is the non-use of circulation pumps between effects, reducing electrical energy consumption and simplifying operation.
Differences
- Customized projects depending on the plant
- Highly robust equipment
- High energy efficiency
- Automated operation
- Low electrical energy consumption
- Stainless steel system
- High operational reliability
- Reduction of operational costs
GRATT's applied engineering ensures efficient integration with the existing industrial process.
Applications
The GRATT Evaporation System is indicated for:
- Corn vinasse concentration
- Sugarcane vinasse concentration
- Industrial processes that require water removal through evaporation
- Recovery of by-products in agro-industrial plants
Applied engineering for high performance
GRATT develops custom-made evaporation systems, considering:
- Vinasse flow
- Solids content
- Integration with DDG
- Plant energy availability
- Layout industrial
By integrating thermal technology, engineering and automation, the GRATT Evaporation System directly contributes to increasing the competitiveness of ethanol plants, reducing costs and raising the technological level of the production process.
Application in the Corn Ethanol Process
In corn ethanol plants, the evaporation system plays a fundamental role in vinasse concentration and in the recovery of soluble solids.
These solids represent about 25% of the vinasse volume and cannot be recovered by conventional processes such as filtration or centrifugation.
Evaporation allows:
- Significant reduction in vinasse volume
- Solids recovery for reuse
- Integration with DDG (Dried Distillers Grains) production
- Reusing water in the industrial or agricultural process
This process increases the overall efficiency of the plant and reduces environmental impact.
