An introduction to conventional GTL processes
The primary objective of Gas-to-Liquids (GTL) technology is to convert natural gas into clean liquid hydrocarbon products. The GTL process involves feeding methane rich natural gas into a reformer or generator where it is converted into Synthesis Gas (Syngas), a combination of carbon monoxide and hydrogen. Subsequently, the Syngas is processed through a Fischer-Tropsch reactor, where it is converted into GTL fuels (Synthetic crudes). A conventional GTL process then requires these hydrocarbons to be upgraded to high quality liquids.
A GTL plant can be configured to produce a wide range of products, from lubricating base oils and waxes through to petrochemical naphtha and specialty chemicals. The mix of products can be altered.
GTL technology yields high value (relative to crude oil) light products. GTL fuel has virtually no sulphur, aromatics or toxics. The resulting GTL diesel can be used as a blend with diesel from refineries to improve the quality of the fuel, making it cleaner, so that it complies with international diesel fuel standards in the transportation market.
The graphic below illustrates the conventional GTL process using SMR +ATR + FT as a case example.
