Spent Acids

Spent Nitration Acids, which may contain Nitric Acid, Sulfuric Acid, water and organics, can be treated and separated using the same process.

The used technology combines the regeneration and recycling of Sulfuric Acid with recovering and high concentration of Nitric Acid.

This process can be adapted for traetment of mixed axids which contain e.g. HF or HCl and Sulfuric Acid.
