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. The 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 cataylst is recovered with multiple filtration steps. The first filtration step involves candle filters inside the hydrogenatros. 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:
They 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.
