Title:
METHOD AND APPARATUS FOR RENDERING POLYCHLORINATED BIPHENYL HARMLESS
Document Type and Number:
WIPO Patent Application WO/2003/026745
Kind Code:
A1
Abstract:
A method for rendering polychlorinated biphenyl harmless, which comprises feeding a liquid containing polychlorinated biphenyl and a mixture of an aluminum oxide and silicon dioxide to an ultrasonic emulsifier (2), conducting an emulsification, allowing the resultant emulsified mixture to fall onto a molten metal in an electric resistance type melting furnace (5) and melt it at a temperature of 1500 to 2000 °, to thereby convert it to a material of a glassy state. The method can be used for rendering polychlorinated biphenyl harmless at low equipment and operation costs with reduced generation of hazardous substances.
