Reduce Power Consumption and Mercury Emissions.

 

Industrie De Nora

is the industry leader in technology and efforts to keep the mercury process competitive by reducing power consumption - Energy Saving Program (ESP). This means that it is possible to obtain the technological limit of the anode(KfCu/Hg 0.045 – 0.050 depending on cell size.)

This package includes following items:

  1. SLM® anode
  2. New anode supporting single-line sub-frames
  3. New ACPD

Industrie De Nora

is the industry leader in technology and efforts to reduce environmental impact of mercury cellrooms by minimizing emissions and improve cellroom safety - Project Mercury Zero (PMZ.)

The Project Mercury Zero program is based on technology and procedures that will limit the number of times a cell must be opened for maintenance, reducing mercury emissions when a cell muust be opened and designing long-life components with minimum mercury pick-up.

This package includes the following items:

1. Ecological package - new components designed with advanced enineering
and alternative materials

    • Inlet and Outlet end-boxes
    • Sidewalls
    • Caustic vessel

2. Minimized cell openings for cleaning and ordinary maintenance

3. Process effluent demercurization treatment

    • solid (sludge; waste graphite & carbon)
    • liquid (waste water; caustic)
    • gas (hydrogen; vent air

Project Mercury Zero developed by Industrie De Nora has achieved the outstanding result to keep mercury emissions below limit fixed by Authorities
