Gas to liquids plant with consecutive fischer-tropsch reactors and hydrogen make-up

A process for converting synthesis gas comprising hydrogen and carbon monoxide into hydrocarbons using a Fischer-Tropsch (F-T) synthesis reaction comprising:

• conveying a gas feed of hydrogen and carbon monoxide to a first F-T reactor;
• removing a hydrocarbon stream from the first F-T reactor;
• removing a first gaseous effluent stream from the first F-T reactor;
• conveying a portion of the first gas effluent stream to a second F-T reactor;
• adding an additional source of hydrogen to the second F-T reactor;
• removing a hydrocarbon stream from the second F-T reactor;
• and
• removing a second gaseous effluent stream from the second F-T reactor.
