Technology conversions

thyssenkrupp Uhde Chlorine Engineers’ membrane electrolysis technology has been established the on the market for more than three decades. The long history of our membrane cell technology is characterized by continuous development activities close to clients’ needs driven by improvements to various factors, such as reliability and power consumption.

thyssenkrupp Uhde Chlorine Engineers looks back on a large number of plants built over many years and equipped with our state-of-the-art technology, making us the market leader for electrolysis plants.

Prior to the establishment of membrane cell technology, diaphragm or mercury electrolysis technologies had been used for industrial-scale chlorine and caustic production from the mid-1900s. However, such technologies have not generally been used in new plants for more than three decades.

thyssenkrupp Uhde Chlorine Engineers has also focused its activities on converting such outdated electrolysis technologies to the latest membrane cell electrolysis technology.

The benefits of plant conversion can be summed up easily. The use of state-of-the-art membrane technology permits significant power savings. Further driving factors include, lower environmental impact and advantages in plant operation such as automated control systems and simplified maintenance.

thyssenkrupp Uhde Chlorine Engineers is the world leader in performing mercury to membrane conversions. We deliver optimum technical concepts combined with vast conversion expertise.

A large percentage of Europe’s mercury cell capacity is being converted to membrane cell technology. thyssenkrupp Uhde Chlorine Engineers has been awarded the majority of these contracts, developing and engineering more than 30 conversion projects over the last twenty years.

Selecting an engineering company and cell supplier like thyssenkrupp Uhde Chlorine Engineers which is well-versed in conversion projects is a reliable choice. Removing mercury from the brine is particularly essential, as mercury can poison both the ion exchange beds and the cathode coating.

In membrane to membrane conversion, older elements are completely replaced by new- generation v6 elements with zero gap technology. The payback period and a replacement concept are first evaluated on the basis of a feasibility study.

In the following planning phase, all required modifications are engineered such as brine and caustic feed stations, the electrical configuration and the instrumentation/interlocking system. During the construction phase, our specialists support you by supervising all reconstruction work until final element assembly. Membrane to membrane conversion guarantees very high savings on power consumption with a simultaneous increase in plant safety through the installation of flooded cell elements.

  • Very high savings on power consumption
  • Minimized investment costs
  • Improved safety levels thanks to flooded cell design
  • Increased current density
  • Pure brine acidification possible

thyssenkrupp Uhde Chlorine Enginees provides diaphragm to membrane and monopolar to bipolar conversions.
