METHOD FOR SOLIDIFYING OIL-CONTAINING SLUDGE

PURPOSE:To solidify an oil-contg. sludge in a short time at a low cost to give a solid product having a strength enough to be directly fed into a blast furnace. CONSTITUTION:An oil-contg. sludge is dehydrated to a water content of 10wt.% or lower, mixed with at least 7wt.% (based on the sludge) pozz...
