Abstract
Process for the industrial production of hyperpure hydrogen peroxide also having high titre up to 60-70% by weight characterized in that the hydrogen peroxide produced in an industrial plant is directly fed to a purification unit, being part of the same production plant, in which the inverted osmosis, separation of the the high purity permeate flow and direct recycle of the concentrated flow to the production plant, are carried out.
Claims9
A process for the industrial production of hyperpure hydrogen peroxide having a titre up to about 60-70% by weight comprising:
- directly feeding hydrogen peroxide, void of stabilizing agent, generated from a production plant to a purification unit as part of the same production plant,
- subjecting the hydrogen peroxide to reverse osmosis, separating high purity permeate flow, and
- directly recycling concentrated hydrogen peroxide to the production plant, thereby producing hyperpure hydrogen peroxide having a titre up to about 60-70% by weight.
