Diaphragm cell . Costacurtas wire cloths are used in the chlorine soda process inside diaphragm cells. During this process, to prevent the chlorine that develops at theg into contact with the catholyte, thepartment is kept separate from thepartment by an ion permeable diaphragm that is impermeable to Cl2 molecules.
An anode conductive material for a caustic soda solution electrolytic cell for producing caustic soda sodium hydroxide and chlorine gas generally uses a graphitized anode. The conductive material of the burner of the electric resistance furnace used for the production of silicon carbide silicon carbide is also a graphitized electrode.
There are two types of electrolysis processes using graphite anodes, one is aqueous solution electrolysis and the other is molten salt electrolysis. The chlor alkali industry that produces electrolyzed brine solutions to produce caustic soda and chlorine is the largest user of graphite anodes.
salt solution brine is electrolyticallyposed to elemental chlorine in thepartment, and sodium hydroxide solution and elemental hydrogen in thepartment. A chemical facility which co produces caustic soda and chlorine is typically referred to as a chlor alkali C/A facility. The overall reaction for the electrolytic production of caustic soda and chlorine
Low quality graphite face low lifetime in presence of caustic soda or caustic potash. For applications requiring long lifetime, higher concentration and concentration GT developed grade GT KELITE+ with a much lower content of phenolic resin which allow resistance up to 50 @ 120°C.
Anode conductive materials for the electrolysis of salt solution of caustic soda sodium hydroxide and chlorine are generally used as graphite anode. The production of carborundum sic used resistance furnace of the furnace head conductive materials, but also the use of graphite electrodes. In addition to the above uses, graphite sheet/graphite rod/graphite products as conductive materials
Due to the corrosive nature of chlorine production, the anode where the chlorine is formed must be non reactive and has been made from platinum metal, graphite called plumbago in Faraday's time, platinized titanium. A mixed metal oxide clad titanium anode also called a dimensionally stable anode is the industrial standard today.
Anodes of coated titanium are suspended in the brine for the production of chlorine, which exits the cell to a collection and processing system. Sodium is electrolyzed in the cell and leaves the first cell amalgamated with the mercury. This amalgam flows into a second electrochemical cell called theposer. Theposer is a cell with graphite as a cathode and the amalgam as the anode.
The electrolyte production of Chlorine and Caustic Soda from Sodium or Potassium Chloride solutions is a process which historically has used activated Titanium anodes now for many decades.Chlorine produced can be used as it is or transformed, still electrolytically, into Hypochlorite, Chlorate or Perchlorate with the aid of activated titanium anodes too.

Caustic soda production. Home / Chemical / Caustic soda production / The chlorine soda process is an electrochemical process that enables the production by electrolysis of chlorine gas, caustic soda and hydrogen, starting from a sodium chloride solution brine. Production of chlorine and soda can take place using diaphragm cells, membrane cells or mercury cells. Diaphragm cell . Costacurta
