Electrolysis of sea water and water disinfection of petrochemical cooling towers with nanotechnology
Seawater electrolysis It is done for various reasons such as hydrogen production or sodium hypochlorite extraction. The hydrogen obtained from the electrolysis of sea water is used in various applications such as fuel cells that can energy and provide electricity for different areas. The use of hypochlorite produced from the electrolysis of sea water is also used Oil and gas and petrochemical industries Reduces problems caused by Sedimentation and corrosion It is used in the parts and pipes of these industries.
In the electrolysis process, a direct electric current and two electrodes are used. In this process, the source of electric current is connected to two electrodes in water with direct current, and the water is decomposed and hydrogen gas is produced in the cathode and oxygen gas is produced in the anode.. In order to electrolyze sea water, electrodes made of mixed metal oxides can be used (MMO)used, which usually have a low wear rate and their geometry remains almost constant. These electrodes, which are made of materials such as IrO2, PtO2 and RuO2, are a suitable replacement for old anodes such as graphite anodes.. But the cost of these anodes is high. Some cheaper anodes also with substrate Titanium It is made pure and a coating of mixed oxides is applied on it. With the development of new electrodes based on Nano technology and replacing them with traditional electrodes made of expensive metallic elements such as Platinum and Iridium The cost of the electrolysis process is reduced and the efficiency of this process is increased.
one Knowledge Base Company Iranians with the application of cover nanometer structure with dimensions of about 20 nanometer Containing various metal oxides has reduced the consumption of expensive catalytic elements. Disinfection of cooling tower water petrochemical Using the electrolysis process, it is one of the industrial achievements of this company.
