Abstract: The present invention is directed to an iron powder commodity and to a process for producing such iron powder commodity comprising dehydrating and de-oiling hot strip mill (HSM) sludge within an inert gas atmosphere contained in a reaction chamber; venting and processing reaction chamber off-gas into a hydrocarbon product; discharging from the reaction chamber a dry de-oiled iron powder commodity that contains nanoparticle and ultrafine particle iron-bearing solids, and beneficiating the discharged iron powder commodity into particles of similar properties.

Abstract: The present invention is directed to a process for treating an oily mixture consisting of hydrocarbons, solid particles, and water. The steps of the process include placing the oily mixture into a reactor chamber, purging the reactor chamber with an inert gas, and creating a steam bath within the inert gas filled reactor chamber, the steam surge freeing hydrocarbon matter from the solid particles. The process further includes elevating reactor chamber temperature to a boiling point temperature corresponding to the hydrocarbons in the oily mixture, the elevated temperature vaporizing the hydrocarbons are vaporized within inert atmosphere. The reaction chamber is vented and the off-gas is processed into a hydrocarbon product while the de-oiled solid particles are discharged from the reaction chamber as a raw material or for disposal.
