The MRS Process is currently in commercial
use treating chlor- alkali wastes and sludges. These materials initially
contain 20-50% by weight of mercury and are being treated to meet a total
residual mercury specification of < 50 ppm.
The work is being performed using an MRS
Mobile Unit having a nominal throughput capacity of 4 tons per day. This
unit has been built to European Community Standards and is CE Marked.
In pilot studies performed for a number of
chlor-alkali producers, the MRS Process has been proven effective in
removing and recovering mercury from a wide variety of plant wastes
containing high concentrations of chloride and sulfur while retaining the
sulfur and chlorine in the treated material and eliminating gaseous sulfur
and chlorine compounds from the process exhaust. These materials include:
- Wastewater Sludge
- The mercury
content was reduced from 19,000 ppm to less than 1 ppm.
- K 106 Waste
- The mercury
content was reduced from 1.4% by weight to less than 1 ppm.
- D 009 Sludge
- The mercury
content was reduced from 44.5% to below the 25 ppm specification.
