Mercury recovery

Applications and design

Process: Indirect Heated Vacuum Thermal Desorption / Vacuum Distillation
Source: By-product from industrial processes, e.g. Chloralkali electrolysis
Mercury contaminated sludge from natural gas drilling, oil and gas NORM
Residues from fungicidal production, wood impregnation, amalgamation or recycled fluorescent tubes
Contaminated production sites and building rubble
Input material: Sludge and filter cake of varying high and low viscosities
Solids, soil, dust, debris, filtration residues, sediments
