The population of the world is enlarging, and living standards will continue to get better for many, so the worldwide necessity for energy is predictable to double by 2050 compared to 2000. Natural gas is in abundance and it’s the cleanest fossil fuel burning. So the gas will play an important role in helping to meet this demand, if we use it in the right way. And for that we’re going to talk about the “GTL TECHNOLOGY”.


GTL (Gas to liquids) is the umbrella term of the technology that is used to describe the process of conversion the natural gas to different high-quality products which are conventionally obtained after oil refining. These products are colorless and odorless among them we find: transport fuels, motor oils and the everyday life necessities like plastics, detergents and cosmetics. And the most important point in this process is that they contain almost low impurity content such as sulphur, nitrogen and aromatics and which we may find in the crude oil.

How does this technology work?

The GTL Process can be divided into three main stages: The first stage is for producing synthesis gas by creating a blend of hydrogen and carbon monoxide through the oxidation of the natural gas with the oxygen and remove all the impurities under high pressure and temperature. The second stage is ‘the Heavy Paraffin Synthesis (HPS)’, where the synthesis gas is converted into hydrocarbon liquids (paraffin molecules) using a catalyst. The final stage includes ‘cracking and isomerization’ where the chains of the
different molecules are split into shorter chains which represent the different valuable products.

What are the GTL Products?

GTL products include: LPG, which is used for cooking or as a fuel heating. Naphtha, it’s useful in the petrochemical industry and a basic material for plastics industry. Normal paraffin or paraffin wax, which is used as a fuel for heating and aircraft. Kerosene; jet engine fuel, it’s also lamps and lighting Fuel. GTL Jet Fuel Blend, which is used to reduce the pollution. GasOil, which is an alternative diesel fuel. Base Oil, which is used for the lubrication of the engines and Gasoline, which is used as fuel for internal-combustion engines.

World’s first and biggest GTL plants

At the present, five commercial – scale GTL plants are in operation. These five plants include:

– Bintulu GTL, Malysia

– Escravos GTL, Nigeria

– Mossel Bay GTL, South Africa

– Oryx GTL, Qatar

– Pearl GTL, Qatar (the largest GTL plant in the world)

These five plants represent nearly 259 Mbpd of capacity. Shell’s Pearl GTL complex represents more than 50% of the world’s total commercial scale GTL capacity (140Mbpd).

The availability of oil is shrinking, the cost continues to increase and the global demand for transport fuels is growing too, so as a conclusion we can say that the GTL Technology is one of the best technologies that can be used to reduce with the atmospheric pollution and to grow up with the economy of the countries.
