Patent ID: 7638040

Claim:
A process for the conversion of contaminated hydrocarbons comprising: contacting the contaminated hydrocarbons with a hot hydrogen rich gas stream in a flash feed separator thereby generating a first vapor stream, and a first liquid stream; stripping the first liquid stream in a stripping column using a stripping gas, thereby generating a second vapor stream, and a residue stream; condense a portion of the second vapor stream to a vapor-liquid stream and separate the vapor-liquid stream, thereby creating a recovered oil stream and a third vapor stream; contacting the first vapor stream and a portion of the recovered oil stream with a hydrodemetallization catalyst in a hydrodemetallization reactor operated at hydrodemetallization conditions, thereby generating a hydrogen-hydrocarbon stream with lower metals content; contacting the hydrogen-hydrocarbon stream with a hydroprocessing catalyst in a hydroprocessing reactor operated at hydroprocessing conditions, thereby generating a hydrocarbon stream with a higher hydrogen content; condensing at least a portion of the higher hydrogen content hydrocarbon stream, thereby generating a hydrogen vapor stream and a second liquid stream comprising hydrocarbons; recovering the second liquid stream.
