Process and plant for producing hydrocarbons from liquid oils

A process for producing a hydrocarbon product, said process comprising the steps of:

• i) conducting a liquid oil stream to a hydroprocessing step for producing a first liquid hydrotreated stream and a second liquid hydrotreated stream, said hydroprocessing step comprising:
• i-1) optionally conducting the liquid oil stream to a stabilization step in a stabilization reaction zone for producing a stabilized liquid oil stream;
• i-2) conducting the liquid oil stream, or the optional stabilized liquid oil stream, to a first hydrodeoxygenation (HDO) step in a HDO reaction zone for producing a first hydrotreated stream;
• i-3) conducting the first hydrotreated stream to a first separation unit for splitting said first hydrotreated stream into a vapor stream and said first liquid hydrotreated stream;
• i-4) conducting the vapor stream to a second hydrodeoxygenation (HDO) step in a HDO reaction zone for producing a second hydrotreated stream;
• i-5) cooling the second hydrotreated stream for providing a cooled second hydrotreated stream, conducting the cooled second hydrotreated stream to a second separation unit and separating therefrom at least an overhead gas stream and said second liquid hydrotreated stream;
• i-6) optionally, combining the first liquid hydrotreated stream with the second liquid hydrotreated stream into a main hydrotreated stream;
• ii) separating from the first or second liquid hydrotreated stream, optionally from said main hydrotreated stream, said hydrocarbon product.
