We can carry out the Basic Design and Detail Design of the adipic acid plant based on low-waste production technology using oxidation of cyclohexanol or its mixtures with cyclohexanone (up to 50% by wt.) by nitric acid in the presence of copper-vanadium catalyst.
The plant capacity is up to 30000 tpy. The process system comprises the following units: reactor loop, crystallization stage, oxidation stage off-gas cleaning, mother liquor processing. The design is based on continuous adipic acid synthesis remarkable for:
- low raw material and auxiliary materials consumption;
- reliable and stable operation of the reactor system;
- rational reaction heat utilization;
- long and stable operation of crystallization unit;
- efficient and simple catalyst regeneration and recycle to the process
- no harmful environmental impact;
- no nonutilizable wastes.
As for quality the produced adipic acid is on a par with foreign analogs.
