Chlor-alkali Electrolyser Cell Room Conversions

Upgrade your Cell Room with INEOS

INEOS Electrochemical Solutions is your trusted partner for modernising chlor-alkali electrolysis facilities. Whether you're upgrading from a mercury, monopolar or diaphragm process to membrane technology, or converting an existing first generation membrane electrolyser to our INEOS BICHLOR platform, we deliver tailored solutions backed by decades of electrochemical expertise.

Upgrade scenarios include:

• Physical end of equipment life - where no amount of refurbishment will maintain a safe and efficient production environment
• No OEM support for existing electrolyser technology.
• Meet sustainability and environmental requirements
• Cell room simplification - opportunity to embrace new methods and technology, use fewer electrolysers or improve layout
• Operate at higher pressure

Mercury or Diaphragm to Membrane Conversion

Membrane technology offers significant advantages over traditional mercury or diaphragm cells, including:

• Lower energy consumption
• Improved product purity
• Reduced maintenance
• Enhanced environmental compliance

We provide full-scope project delivery - from feasibility and design through to commissioning and optimisation - ensuring a smooth transition with disruption to operations minimised where possible.

Membrane to Membrane Conversion:
Upgrade to INEOS BICHLOR

Already operating membrane cells? INEOS Electrochemical Solutions offer engineering services to transition your existing membrane electrolysers to our BICHLOR technology - designed for superior performance, reliability, and lifecycle cost efficiency.

Benefits of converting to BICHLOR electrolysers:

• Optimised cell design for reduced energy usage (1941 kWhr/tonne NaOH) 
• Operate at higher pressure (atmospheric to 1 barg*)
• Large effective working area of 3.4m² per cell / module means fewer cell / modules are required per tonne of NaOH, enabling maintenance simplification and cost reduction
  • • Alternatively, by operating the same number of BICHLOR cells / modules as the existing facility, an increase in output capacity can be unlocked
• Proven durability and long operating life
• Compatibility with existing infrastructure, minimising capital investment
• Access to INEOS technical support and global service network
  
  *subject to restrictions of local / national pressurised system regulations
