This first reactor in the series of two is known as the hydrogenator as hydgrogen is also fed to this reactor and a hydrogenation reaction occurs over a Ni or Pd catalysts. In the second reactor, air or oxygen enriched air is introduced to the work solution to reverse the previous reaction via oxidation. The contaminated air from the oxidizer is fed to a carbon adsorption unit and then to a vent condenser.
Water is fed to the extractor and acts as the extracting agent.
The hydrogen peroxide is miscible in water while the solvents are not. Then the H 2 O 2 -water layer can be removed and sent to Vacuum Column I and the solvent is sent to be purified before it is recycled. While water is removed as an overhead product, the hydrogen peroxide is further concentrated as the bottom product.
