How it works
In a GTL plant the feed gas is first converted into syngas through a steam reforming and partial oxidation process. To achieve this, very large volumes of oxygen or air, are necessary. Therefore a large air separation unit (ASU) is often associated with the GTL plant.
The syngas, consisting of hydrogen and carbon monoxide with a 2:1 ratio, is then compressed and fed to the Fischer-Tropsch (FT) synthesis reactors where the chain growth reaction occurs in the presence of a suitable catalyst to form liquid hydrocarbons. Light or heavy syncrude may be obtained, depending on the temperature, pressure and catalyst.
The product of the FT reaction can be further upgraded in a typical refining unit that may be associated with the GTL plant.
