Hydrogen Peroxide

Hydrogen Peroxide

 

  • • hydrogen peroxide is a mass produced chemical widely used for oxidizing and bleaching in the pulp and paper, textile, chemical, pharmaceutical, cosmetic, and electronics industries

  • • environmentally safe chemical alternative to chlorine

  • • ability to neutralize hazardous pollutants in industrial waste and wastewater streams.

  • • most common method used to produce hydrogen peroxide is auto-oxidation process, using a working solution (usually an alkylquinone in an organic solvent solution) produces the peroxide which is extracted by contact with deionized water

  • • hydroalkylquinone is formed by reduction of alkylquinone with hydrogen in a reactor

  • • hydroalkylquinone produced goes through several stages of filtration to remove and recover precious catalyst

  • • it is then fed into an oxidation reactor where air is blown through, producing hydrogen peroxide

  • • hydrogen peroxide is separated from the organic phase in a water extractor to yield 35 – 45% hydrogen peroxide solution

  • • alkylquinone is purified and recycled back to the hydrogenation reactor

  • • peroxide is treated to remove organic impurities processed to achieve the required final product concentration

  • • it is then loaded into rail tank cars or drums for distribution

 

Recommended Products

 

  • • Primary Catalyst Recovery:  Regenerable backwash filters offering benefits of process economy, reliable filtration, low maintenance, and reduction in material handling problems. 

  • • Secondary and Tertiary Catalyst Recovery:  Cartridge filter is required to remove the catalyst and to ensure the safety of downstream process operation. 

  • • Water Filtration: Jumbo filters are used to removed contaminants, such as iron oxides, and to improve product quality. The cleanliness of the final product is maximized by use of clean extractor water from which the product Is made. 

  • • Aqueous Phase Removal From Working Solution:  Coalescer are used for quantitative removal of free water down to 15 ppmv. 

  • • Regeneration Filter:  Filters are recommended to filter a 10% stream of the working solution to remove absorbent, which can contaminate the stream.  The filters provide reproducible fluid quality and longer service life.  Thus, spent filter cartridge disposal and operator exposure to toxic fluid are minimized. 

  • • Final Product Filtration: Hydrogen peroxide can be shipped in several grades and concentrations ranging from 5 – 70%.  Prior to shipping the final product or storing in storage tanks, the product is filtered to ensure quality.  End use of the product determines the filtration level required.  For less stringent end-use requirements (removal ratings from 2 – 20 µm), use  HFGP Series filters.  For more stringent requirements, PVDF Series filters should be used.
