RHDS residual Hydro Desulfurization VRDS Vacuum Residue Desulfurization Device for oil-cleaning of used-catalyst for RHDS and VRDS desulfurization

摘要

The present invention relates to a process for removing sulfur and heavy metals that cause inactivation of a desulfurized spent catalyst generated in a residual hydrodesulfurization (RHDS) and a vacuum residual desulfurization (VRDS) process, The present invention relates to an oil cleansing device for desulfurized spent catalysts in a residual hydrodesulfurization (RHDS) and a vacuum residual desulfurization (VRDS) process for removing oil contained in a desulfurized waste catalyst. According to an aspect of the present invention, there is provided an oil cleaning apparatus comprising: a storage hopper for storing waste catalyst containing oil; A raw material injection regulator formed at a lower portion of the storage hopper for quantitatively controlling a waste catalyst dispensed from the storage hopper; A mesh basket for receiving waste catalysts dispensed quantitatively from the feedstock regulator; A transfer hoist for transferring the mesh basket containing spent catalyst to a solvent bath; A plurality of solvent water tanks for receiving the mesh basket transferred from the transfer hoist to dissolve the oil contained in the waste catalyst; A transfer conveyor for transferring and transporting waste catalysts descending from the mesh baskets passing through the plurality of solvent water tanks; An explosion-proof blower for removing the solvent remaining in the spent catalyst by applying hot air to the waste catalyst conveyed by the conveying conveyor; And a gas absorption tower for purifying the discharged gas.
