The chlor-alkali process is an industrial process for the electrolysis of NaCl solution. It is the technology used to produce chlorine and sodium hydroxide (lye/caustic soda), the commodity chemicals that are required by different industries. Usually, the process is conducted on the brine (an aqueous solution of NaCl), which produces NaOH, hydrogen, and chlorine as a result. Dhofar-EWC is developing Dhofar Chlor-alkali project in Salalah Free Zone. The project is to produce 20 KTPY of caustic Soda (dry basis) in first phase and to double the capacity with renewable energy sources in the second phase. The plant products including surplus Hydrogen shall have the minimum carbon footprint and will be supplied to the growing green chemicals market.
