Thermal Integration

Comprehensive energy management.

Thermally integrated designs

Heat recovery from thermal processes and re-use of secondary energy within and across process units allow a more effective use of primary energy. Besides resource conservation, successful solutions consider the investment costs and the available infrastructure too.

Process optimization of this sort cuts operating costs and improves the greenhouse gas performance of the plant.

VBC Distillation Thermal Integration
Integrated distillation/dehydration/evaporation

Vogelbusch ethanol plants achieve exceptional energy efficiency with proprietary systems such as multipressure distillation coupled with direct feed to the molecular sieves for dehydration, and a multi-effect evaporation, driven by waste heat.

The evaporator can run on waste heat from distillation or DDGS dryer, while the condensation from the dehydrated alcohol vapor in a molecular sieve can provide the heat for mash preheating. With thermal integration of rectification and dehydration, using latent heat of feed vapors, there is virtually no steam demand for the dehydration unit (illustration).

Further reduction of energy consumption is obtained by returning still wash, condensates and lutter water to the process so as to re-use heat and water.

Specialized custom solutions

Vogelbusch takes a variety of approaches to thermal integration. Configurations of our proprietary systems are selected in each particular case, according to

  • the properties of the raw materials used,
  • the planned investment costs and
  • local energy costs. 
Saving energy in ethanol production

Our advanced techniques save energy througout the process plant.
