Chapter 9:

Concentrating HTP from Low Grade Peroxide Solutions

• A major obstacle that this program has had to overcome was the procurement of high-grade peroxide for the phase 1 tests.
  • Previously, small quantities of high test peroxide (HTP) in the 70-95% concentration range could be procured domestically commercially from one of two sources,
    • 1) FMC Corporation (USA), or
    • 2) Peroxide Propulsion, Inc. (Sweden).
  • In 2012 FMC Corporation completed the sale of its peroxygens business to PeroxyChem, an affiliate of One Equity Partners, the private investment arm of J.P. Morgan Chase & Co.
  • Also, in 2009 Peroxide Propulsion ceased retail sales of high-test peroxide, deeming the liability risk as being too high for profitability.
  • Unfortunately, the remaining commercial source for HTP, PeroxyChem has instituted a minimum order policy for HTP -- a pallet consisting of 4 x 55 gallon drums, or approximately 1.21 metric tons of decomposable material.
  • USU currently does not have the existing infrastructure to safely store and work with such a large amount of material. The infrastructure modifications that would be required to meet federal regulations far exceed the available budget.
    
• THus, As an Operating Principle for this test series, we will only keep on hand the amount of HTP (> 70% concentration) necessary to complete two days worth of testing.
  • HTP solutions > 70% will be condensed from 50% solutions available at the Chem store.
  • Only 50% or lower concentration of H2O2 will be stored for more than two days.
