Steel industry sludge treatment includes heating for condensation of the evolved organic vapor and off loading of the inorganic metal compounds

摘要

The steel industry sludge treatment involves heating to 300[deg]C of water, organic-chain compounds and inorganic metal compounds based sludge, for condensation at 100-200[deg]C of the organic vapor evolved with the water vapor. An independent claim is also included for an apparatus implementing the process. The apparatus has a heat-insulated closed tubular heater with a bottom outlet for the inorganic metal compounds.
