摘要： A flexible once-through process for hydroprocessing heavy oil feedstock is disclosed. The process employs a plurality of contacting zones and at least a separation zone to convert at least a portion of the heavy oil feedstock to lower boiling hydrocarbons, forming upgraded products. The contacting zones operate under hydrocracking conditions, employing a slurry catalyst which comprises an active metal catalyst having an average particle size of at least 1 micron in a hydrocarbon oil diluent, at a concentration of greater than 500 wppm of active metal catalyst to heavy oil feedstock. The plurality of contacting zones and separation zones are configured in a permutable fashion allowing the once-through process to be flexible operating in various modes: a sequential mode; a parallel mode; a combination of parallel and sequential mode; all online; some online and some on stand-by; some online and some off-line; a parallel mode with the effluent stream from the contacting zone being sent to at least a separation zone in series with the contacting zone; a parallel mode with the effluent stream from the contacting zone being combined with an effluent stream from at least another contacting zone and sent to the separation zone; and combinations thereof. In one embodiment, the effluent from a contacting zone is sent to the next contacting zone in series for further upgrade, with the next contacting zone having a pressure drop of at most 100 psi, with the pressure drop is not due to a pressure reducing device as in the prior art. In one embodiment, at least an additive material selected from inhibitor additives, anti-foam agents, stabilizers, metal scavengers, metal contaminant removers, metal passivators, and sacrificial materials, in an amount of less than 1 wt. % of the heavy oil feedstock, is added to at least one of the contacting zones.

摘要： Processes and systems for upgrading hydrocracker unconverted heavy oil are provided. The invention is useful in upgrading unconverted heavy oil such as resid derived from hydrocracking processes and may be used to upgrade such resids to form fuel oils such as low sulfur fuel oil for marine use. A combination of solutions is applied in the invention including applying a separation process for unconverted heavy oil comprising hydrocracker resid, combining an aromatic feed with the unconverted heavy oil, followed by subjecting the unconverted heavy oil to a hydrotreating process.

摘要： Se describen los sistemas y métodos para hidroprocesar un material de alimentación de petróleo pesado con depósitos reducidos de petróleo pesado, el sistema emplea una pluralidad de zonas de contacto y zonas de separación bajo condiciones de hidrodesintegración, para convertir al menos una porción del material de alimentación de petróleo pesado en hidrocarburos de menor punto de ebullición, formando productos mejorados, en donde el agua y/o el vapor es opcionalmente inyectado dentro de la primera zona de contacto en una cantidad de 1 a 25% en peso sobre el peso del material de alimentación de petróleo pesado. En una modalidad, la primera zona de contacto es operada a una temperatura al menos 5.5°C (10°F) menor que una siguiente zona de contacto. Las zonas de contacto operan bajo condiciones de hidrodesintegración, empleando un catalizador en suspensión para mejorar el material de alimentación de petróleo pesado, formando productos mejorados de hidrocarburos de menor punto de ebullición. En las zonas de separación, los productos mejorados son retirados en la parte superior, y opcionalmente, adicionalmente tratados en un hidrotratador en línea. Al menos una porción de las fracciones no volátiles recuperadas de al menos una de las zonas de separación, es reciclada nuevamente hacia la primera zona de contacto en el sistema, en una cantidad en el intervalo de 3 a 50% en peso del material de alimentación de petróleo pesado. En una modalidad, al menos algo del material de alimentación de petróleo pesado es suministrado al menos a una zona de contacto diferente de la primera zona de contacto, y/o al menos algo del catalizador en suspensión fresco es suministrado al menos a una zona de contacto diferente de la primera zona de contacto. En una modalidad, al menos una porción de las fracciones no volátiles recuperadas de al menos una de las zonas de separación es enviada a la unidad de desasfaltado con solvente inter-etapas, para separar el material de alimentación de petróleo pesado no convertido en aceite desasfaltado y asfaltenos. La corriente de petróleo desasfaltado es enviada a una de las zonas de contacto para el mejoramiento adicional.

In the separation zones, upgraded products are removed overhead and optionally, further treated in an in-line hydrotreater. At least a portion of the non-volatile fractions recovered from at least one of the separation zones is recycled back to the first contacting zone in the system, in an amount ranging between 3 to 50 wt. % of the heavy oil feedstock. In one embodiment, at least some of the heavy oil feedstock is supplied to at least a contacting zone other than the first contacting zone and / or at least some of the fresh slurry catalyst is supplied to at least a contacting zone other than the first contacting zone. In one embodiment, at least a portion of the non-volatile fractions recovered from at least one of the separation zones is sent to the interstage solvent deasphalting unit, for separating unconverted heavy oil feedstock into deasphalted oil and asphaltenes. The deasphalted oil stream is sent to one of the contacting zones for further upgrade.
