  • Patent number: 11859142
    Abstract: A hydrocracking process for maximization of naphtha while producing base oil is disclosed. The hydrocracking process comprises hydrocracking a hydrocarbon feed stream in a hydrocracking unit in the presence of a hydrogen stream and a hydrocracking catalyst to produce a hydrocracked effluent stream. The hydrocracked effluent stream is separated in a separator to provide a vapor hydrocracked stream and a liquid hydrocracked stream. The liquid hydrocracked stream is fractionated to provide a naphtha stream, a kerosene stream, a diesel stream and a first unconverted oil stream. A recycle stream comprising a portion of the kerosene stream, a portion of the diesel stream, and a portion of the first unconverted oil stream is recycled to the hydrocracking unit to provide a second unconverted oil stream. A remaining portion of the first unconverted oil stream is withdrawn for base oil production.

  • Patent number: 9901849
    Abstract: A process for filtering a liquid stream from a fixed bed reaction zone in order to remove catalyst fines contained in the stream. The effluent stream is passed to a filtering section which may contain at least two filtering vessels. Each filtering vessel includes at least two differently filtering sections, each section designed to collect differently sized particles. If a pressure drop occurs in one of the filtering vessels, it may be taken offline to remove the filtering sections and recover the metal in the particles collected on the filtering sections. The other filtering vessel can remain online to allow the filtering process to be continuous. Metal on the catalyst fines may be recovered.

  • Patent number: 9809761
    Abstract: Hydrocarbon processing apparatuses and methods of refining hydrocarbons are provided herein. In an embodiment, a method of refining hydrocarbons includes providing a cracked stream that includes a sulfur-containing component and cracked hydrocarbons. The cracked stream is compressed to produce a pressurized cracked stream. The pressurized cracked stream is separated to produce a pressurized vapor stream and a liquid hydrocarbon stream. The pressurized vapor stream includes C4? hydrocarbons and the liquid hydrocarbon stream includes C3+ hydrocarbons. The liquid hydrocarbon stream is separated to produce a first liquid absorption stream that includes C5+ hydrocarbons and a C4? hydrocarbon stream. C3+ hydrocarbons are absorbed from the pressurized vapor stream through liquid-vapor phase absorption using the first liquid absorption stream. The sulfur-containing component is removed prior to absorbing C3+ hydrocarbons from the pressurized vapor stream.
