Process Description by the hydrogen peroxide production line
The production of hydrogen peroxide include two parts: The
preparation of nearly pure hydrogen gas and the production of
hydrogen peroxide product. Details are given as below:
1. Hydrogen Preparation by our hydrogen peroxide machine/hydrogen
peroxide production line:
(1)Natural gas cracking:
Natural gas, after pre-heating and desulphurization, is mixed with
steam in a fixed proportion and sent to the heating coil of
convection section of cracking furnace. Wherein it goes through
catalytic cracking reaction to form H2CO2 and CO at 800-850 degree.
(2)Hydrogen gas purification
The concentration of hydrogen gas from cracking furnace is 73%.
Other compositions include CO2COCH4. In order to remove these
undesired compositions, pressure swing absorption is used. Finally,
high pure hydrogen gas(concentration: ‰¥ 98.5%) is obtained.
2. Hydrogen peroxide production process by the hydrogen peroxide
equipment of hydrogen peroxide machine manufacturers
(1)Diethyl anthraquinone is dissolved in two solvents (heavy
aromatics and tri-octyl phosphate) in storage tank. Collectively
the anthraquinone and solvents are called the working solution.
This working solution is stirred and heated until being totally
melted, cooled down to ambient temperature, and washed by diluted
hydrogen peroxide solution and ion-free water for next use.
(2)K2CO3 solution in a certain concentration is made up of ion-free
water and K2CO3 powder by pump circulation in another storage tank.
The used K2CO3 powder can either be fresh or recycled from the
dryer via filtration and evaporation.
(3)The working solution is pumped to the fixed bed hydrogenation
reactor and reacted with pure hydrogen in presence of Pd-catalyst.
(4)The hydrogenation-resulting solution is cooled, filtered to
removed Pd, and then fed to the oxidation reactor bottom.
(5)Compressed air is divided into two streams. One is sent to the
upper section of the oxidation reactor bottom and the other to the
lower section of the oxidation reactor bottom.
(6)In oxidation reactor, the hydrogenation-resulting solution
reacts with oxygen in the compressed air under a certain
temperature and pressure to form hydrogen peroxide. The generated
off-gas is recovered and scrubbed through separator prior to
(7)The resultant hydrogen peroxide solution is supplied to the
extraction tower and extracted by ion-free water to form hydrogen
peroxide with 35-36% concentration.
(8)The drained waste water from the bottom of extraction tower is
sent to drying tower to concentrate potassium carbonate solution
for re-use, and the excess waste water, after treatment, is
