MRS's
Mercury Removal/Recovery (MR2) Process is a mobile
or fixed-site medium-temperature thermal desorption method for removing
mercury from a wide variety of solid materials that has been proven to:
- consistently reduce the mercury content of
the treated material to less than one (1) part per million (< 1 ppm)
regardless of the level and form of mercury originally contained,
- produce a 99% pure metallic mercury
suitable for direct refining to high purity metal,
- recover mercury from compounds such as
mercury oxide, mercury chloride, and mercury sulfide,
- prevent the released sulfur and/or
chlorine from entering the process exhaust,
- operate without generating any secondary
liquid, solid, or gaseous secondary waste,
- produce a gaseous effluent that meets all
clean air standards,
- efficiently treat materials having high
moisture contents, and
- effectively utilize "double
containment" for added worker and environmental safety.
Introduced commercially in 1994, the MRS
Process has been successful in removing and recovering mercury from a wide
variety of materials, including soils, chlor-alkali wastes, copper and
precious metals smelting and refining by-products, waste water treatment
sludges, catalysts, carbon products, batteries, and fluorescent bulbs. The
process has also been demonstrated to be effective in removing mercury from
low-level radioactive wastes without removing or dispersing radioactive
particles from the material.
