Over many years ALVIGO Group of Companies conducted scientific/research and designing works for cyclohexanol oxidation process with nitric acid and mixture of cyclohexanol and cyclohexanone with nitric acid into adipic acid.

The results of these researches were significant changes in adipic acid production scheme, making possible to raise the technical level of product production. Based on proprietary developments adipic acid production unit was created as a part of stage for obtaining mixture of cyclohexanol with cyclohexanone out of benzene and oxidation stage of this mixture into adipic acid.

The advantages of suggested adipic acid synthesis process are the following:

  • low consumption of raw materials and additional materials;
  • reliability, stability and safety operation of reactor unit;
  • sustainable use of reaction heat;
  • running and accuracy operation of crystallization unit;
  • low environmental impact;
  • low quantity of unusable waste.

At present time ALVIGO Group of Companies specialists conduct developments aimed to improve the existing adipic acid plants, reduce process consumption parameters, increase the product qualitative features as well as improve the environmental performance of plant.
