Overview of ETCi's Technologies
DRY SEPARATORS
Magnetic separator chain used in the MagMill configuration. It consists of a belt separator to remove strongly magnetic contaminants. The product of the belt separator is fed to the second stage electromagnet for removal of feebly magnetic contaminants.
Stand-alone belt separator. One version was tested in processing coal, fly ash, and nickeliferous-pyrrhotite. The ElectriMag version combines the belt magnetic separator with dry triboelectric separation.
3,000 lb/hr MagMill prototype. A modification of the separators has been moved to the DTE Energy Services Petcoke Grinding Facility in Vicksburg, MS, where a MagMill demonstration unit is being installed.
VacuMag Separator for recovery of magnetic components from fly ash.
HYDROCARBON LIQUIDS
Apparatus for removing strongly magnetic particles from viscous flows. A 50 barrel per day prototype was tested in separation of sub-micron sized iron catalysts from 500oF Fischer-Tropsch wax. A non-exclusive license for testing the process has been taken by a major developer of coal-to-liquids technology.
Photo of effect of magnetic field on particle shape using Magnetostatic Coalescence to break emulsions. Tested in recovery of naphthenic and cresylic acid from emulsions made in caustic dewatering of crude oil.
