The paper introduces the project of treatment of the oily waste water in the residue oil tank zone by advective separation of oil-blending and solidification gas-floating-coke filtration process.

Simulation research on the EAF dust online recycling and zinc oxide separation with coke bed filter was carried out by heating coke/dust samples in CO/CO2 gas mixture.

By using minute particles of SiO2 as dust,simulation research on the EAF dust collection characteristics by cold model coke bed filter was carried out: For fixed bed filter,it was found that the longitudinal distribution of static hold up at steady state can be regarded as constant for a certain gas flow rate condition.
