Recycling Natural Gas: The GTL Technology

Cividac's components for the petrochemical sector are also employed in state-of-the-art plants like those for the GTL (Gas to Liquid) process, whereby liquid fuels are synthetized from natural gasses.
When oil is extracted from the well, it is often mixed with natural gas, which is called "associated." This gas can be found dissolved in the oil, or as a separate layer on the surface.
In the past, extraction plants had no infrastructure with which to transport this gas, which was therefore considered as waste product and burnt. In fact, one of the images associated with oil extraction is the steel tower with a flame on top, constantly burning.
This procedure has obvious limitations. Firstly, although burning gas is less detrimental to the environment than releasing it in its natural state, it still contributes to global warming. Secondly, it is a waste of a potentially useful energy source.
The research of alternative solutions, led to the GTL process, which transforms natural gas into liquid fuel (for example diesel, petrol, or naphtha), which in turn can be easily transported through the already-existing infrastructures of the extraction plant.
The GTL process started to be used during the Nineties, but it had actually been discovered seventy years prior, in the Twenties. It is also used to synthetize Eco diesel fuel from the gas produced by biomass power plants.
