Detailed Report
Unit Operation Summary
Hydrogen Peroxide is produced by the
hydrogenation of Quinone followed by
the
oxidation
of
the
resultant
Hydroquinone to produce Hydrogen
Peroxide and the original Quinone
molecule which is recycled.
The
Hydrogen Peroxide is produced at 35%
in water and can be concentrated to
65% in the concentration facility.
Unit Operation Review
Hydrogenation
Quinone is reacted with Hydrogen using a palladium catalyst
at 1.0-1.5 bar pressure. The catalyst has been removed from
the process.
They hydrogenator is of stainless steel
construction and is 12.5’ diameter by 18’ tall. This is an
exothermic reaction so the reactor has internal cooling as
well as an inlet cooler

Filtration
The palladium catalyst is recovered with multiple filtration steps. The
first filtration step involves candle filters inside the hydrogenators.
Two steps of leaf filtration are used after that.
All of the filtering
equipment is stainless steel.

Oxidation
The Hydroquinone is then reacted with Oxygen from the Elliott Oxidizer Air
Compressors to produce Hydrogen Peroxide. In this same reaction, the
Hydroquinone returns to its original Quinone form. The stainless steel
oxidizers (2) are 8’ diameter by 41’ tall. They operate at 3 bar pressure and are
fed with a 4,600 NCMH air compressor.

Extraction & Purification
The Hydrogen Peroxide is then extracted with water with an exit
concentration of about 35%. Some organic compounds are also
removed in this stage. The extractor is stainless steel and is 5’
diameter by 60’ tall.

Concentration
Hydrogen Peroxide from the extractor can be
concentrated up to 60% in the concentration facility
by vaporization with steam and absorption in a
packed column. The vaporizer is stainless at 4.5’
diameter by 12’ tall.
Building
The building footprint is apporximately 100’ x 80’ at the
bottom and 60’ x 40’ for the top three floors. It is seven
floors tall which makes it about 100’ tall.
