Production of Chlor-alkali
Mersen is a technical member of EUROCHLOR.
Focus on the electrolysis process / HCL Synthesis
The heart of Chlor-Alkali process is the electrolysis of NaCl brine (sodium chloride) or KCl brine (potassium chloride) to produce chlorine (Cl2), caustic soda (NaOH, sodium hydroxide) or caustic potash (KOH, potassium hydroxide) and hydrogen (H2), which are commodity chemicals required by industry.
Mersen has a long-term partnership agreement with APPLITEK (an on-line analyser company) whose objective it to improve the Sintaclor safety and control.
Production of ultra-pure HCl by synthesis of Cl2 and H2.
Sintaclor is the best solution to obtain ultra-pure HCl (< 1ppm free Cl2)
Mersen has installed more than 600 Cl2 burner units in the world, since 1960, cumulating a yearly production of 9 million t HCl. The leading producers of Cl2 and H2 trust our know-how.
Mersen has enlarged its Cl2 burner portfolio with the third generation called Sintaclor Eco&Flex.
