Abstract
Methods and apparatuses for processing hydrocarbons are provided. In one embodiment, a method for processing hydrocarbons includes providing a stream of olefins including normal olefins and non-normal olefins. The method includes separating the normal olefins from the non-normal olefins to form a stream of normal olefins. Further, the method polymerizes the stream of normal olefins to form a stream of polymerized normal olefins. The method also includes saturating the stream of polymerized normal olefins to form a stream of normal paraffins.
Claims23
A method for processing hydrocarbons, the method comprising the steps of:
- providing a stream of olefins including normal olefins and non-normal olefins;
- separating the normal olefins from the non-normal olefins to form a stream of normal olefins;
- polymerizing the stream of normal olefins to form a stream of polymerized normal olefins;
- saturating the stream of polymerized normal olefins to form a stream of normal paraffins;
- and
- reforming the stream of normal paraffins to form a stream of aromatics.
A method for processing hydrocarbons, the method comprising the steps of:
- introducing a stream of mixed C4 olefins to a reaction zone;
- converting a portion of the stream of mixed C4 olefins to a C5 species;
- separating the C5 species from unconverted C4 olefins;
- polymerizing the unconverted C4 olefins to form C8 olefins;
- and
- saturating the C8 olefins to form C8 paraffins.
An apparatus for processing hydrocarbons comprising:
- a separation zone configured to receive a stream of olefins including normal olefins and non-normal olefins and to separate the normal olefins from the non-normal olefins to form a stream of normal olefins;
- a polymerization zone configured to polymerize the stream of normal olefins to form a stream of polymerized normal olefins;
- and
- a saturation zone configured to saturate the stream of polymerized normal olefins to form a stream of normal paraffins.
A method for processing hydrocarbons, the method comprising the steps of:
- providing a stream of mixed C4 olefins including normal olefins and non-normal olefins;

- saturating the stream of polymerized normal olefins to form a stream of normal paraffins.
A method for processing hydrocarbons, the method comprising the steps of:
- providing a stream of mixed C4 olefins including normal olefins and non-normal olefins;
- separating the normal olefins from the non-normal olefins to form a stream of normal olefins by converting isobutene to methyl tertiary butyl ether (MTBE) and separating the MTBE from unconverted C4 olefins;
- polymerizing the stream of normal olefins to form a stream of polymerized normal olefins;
- and
- saturating the stream of polymerized normal olefins to form a stream of normal paraffins.
A method for processing hydrocarbons, the method comprising the steps of:
