HYDECAT - the innovative solution

HYDECAT™ - the innovative solution

The Johnson Matthey HYDECAT process is a catalytic method of removing hypochlorite from chlorinated caustic streams, using a heterogeneous supported nickel catalyst and a modular fixed bed reactor.

HYDECAT - one catalyst, three processes

Using HYDECAT 88-2, there are three options for the positioning and design of HYDECAT units to treat waste hypochlorite streams:

  • HYDECAT TD - Total destruction - the traditional end-of-pipe application.
  • HYDECAT PD - Partial destruction - usually followed by chemical polishing.
  • HYDECAT ID - Integrated destruction -  in the scrubber liquid recirculation loop.

Chlorine makes a vital contribution to the health and quality of modern everyday life: as a disinfectant and in the manufacture of plastics, pharmaceuticals and many essential products. However, there is increasing pressure to reduce the level of chlorine and chlorinated organic species released to the environment because of the potential effect on the eco-cycle.
