 SESPI have designed a simple and effective membrane electrolyzer to be fitted in the small/medium industrial units which can take advantage either of chlorine or caustic (or possibly both products) for the commercialization of derivatives.
Such production unit is :
- easily managed also by operators not necessarily skilled in chlorine handling unit
- easily following the various market demands on both peak and bottom requests
SESPI electrolyzer has been designed to meet the request of the middle and small consumers of chlorine and caustic. It can be installed in a single unit arrangement or in multiple units, if higher capacities are requested.
SESPI electrolyzer is simple to be operated, has good flexibility and easy maintenance.
Our Company also supplies all the necessary equipment to prepare and purify the brine for the membrane electrolyzer operation and the chlorine, caustic and hydrogen handling and distribution.
SESPI is in the position to supply its experience and assistance necessary for helping the customers to operate this equipment satisfactorily.
ELECTROLYSIS
The electrolysis process takes place when, applying a difference of electric potential to an acqueos solution of acids, bases, salts, a circulation of D.C. current strictly related to mass transfer phenomena is created in the solution itself.
The driving means of the electric charges are not the molecules neither of the solvent nor of the dissolved compound, but only parts of themselves.
Acid, bases and salts, when dissolved in definite solvents, have their molecules divided in two parts and, after the applying of D.C. current, one part (anion) migrates and deposits itself at the positive electric polarity or anode, whilst the other (cation) at the negative electric polarity or cathode. These parts of the molecule can be atoms or groups of atoms.
This is the separation that occurs, for instance, to the atoms of Chlorine and Sodium or Chlorine and Potassium when dissolved into their conductive electrolytic solution in which they are contained in ionic form : a consequence of what described above is, for example, Chlorine and Caustic Soda or Potash production in the electrochemical industry.
