What are the dimensions and space requirements for the Phase Two Chemicals’ hydrogen peroxide system?
The standard dimensions of the skid-mounted equipment are 11.4m x 2.1m x 2.5m per 1.5 MT/day production system. Indoors installation is preferred, but outdoor installations are possible. The relative humidity of the equipment location should not exceed 60%.
What are the input requirements for the hydrogen peroxide generation system?
Electricity, oxygen, process water, cooling water, and caustic soda. Caustic soda is not consumed but passed through to the product solution.
What are the outputs of the hydrogen peroxide generation system? What is the ratio of sodium hydroxide to hydrogen peroxide in the bleach solution? Is the ratio fixed?
The equipment outputs a mixed solution of aqueous sodium hydroxide and hydrogen peroxide. The cathodic reaction results in a fixed ratio at which sodium hydroxide and hydrogen peroxide are generated, with a theoretical mass fraction ratio of sodium hydroxide to hydrogen peroxide of 2.35. In practice the ratio may be between 2.2 and 2.4, subject to site specific operating conditions.
Will extreme temperatures affect the operation of the equipment or lead to freezing or increased energy consumption?
The ambient operating temperature of the system should be maintained between 4-40 °C. While indoor operation is preferred for more stable temperatures, outdoor installations can be supported. Because the system generates heat during operation installation in cold environments can be supported with adequate freeze protection (including insulation or auxiliary heat sources for outages) with minimal increased energy consumption. Installation in hot environments will result in increased cooling water consumption but no additional energy consumption for the electrochemical process.
What is the temperature of the solution output by the hydrogen peroxide generation equipment?
The temperature of the solution output is 40-50 °C.
What is the overall weight of the hydrogen peroxide equipment?
The P1528 equipment weighs up to 12 metric tons when fully loaded with operating fluids. A separate AC to DC rectifier (included with the generator, but preferably installed in adjoining electrical rooms) is approximately 1 cubic meter and weights 1.5 tons. Water purification and oxygen generation equipment can be supplied separately. Design parameters are site specific.
Does the hydrogen peroxide generation equipment require separate operating software and terminals? Can it be connected to the customer’s DCS?
The equipment is controlled via PLC (Programmable Logic Controller) and can be operated through a touchscreen and computer terminal or remotely via cellular data connection. The equipment can communicate with the customer’s DCS (Distributed Control System) system for high-level equipment status and safety interlock monitoring in accordance with customer requests.
Where is your hydrogen peroxide equipment produced?
We are a global company with R&D centers in Shanghai and Boston. Our equipment and component production factories are located in Shaoxing, Zhejiang Province and Lancaster, Massachusetts.
How long does it take the system to produce hydrogen peroxide?
The equipment can be started up within 15-30 minutes. Hydrogen peroxide will be produced in about 30 minutes.
How much oxygen is consumed for producing one ton of hydrogen peroxide? What purity is required?
The specific oxygen consumption is dependent on the purity of supply. Lower purity requires excess venting to remove inerts that would negatively impact system performance. At high purity (e.g. 99.5% cryogenically generated oxygen), the requirement is 0.52 tons of oxygen per ton of hydrogen peroxide. At moderate purity, (e.g. 93% with pressure swing adsorption (PSA) generated oxygen) the requirement is 0.9 tons of oxygen per ton of hydrogen peroxide. Lower purity of oxygen supply is typically not feasible.
Are on-site personnel required to operate the hydrogen peroxide generation equipment? Is inspection required?
The equipment runs fully automatically during operation and does not require continuous monitoring. The automated PLC control system is fully safety interlocked for safe, autonomous operation. Under normal circumstances, the equipment shall be inspected on a regular basis, typically once or twice a week.
Who maintains the equipment? What is the maintenance schedule?
Phase Two Chemicals or its representatives conduct routine maintenance and upkeep of the equipment. Filter changes, etc. are performed as-needed. Comprehensive maintenance occurs on an annual schedule.
