Processing of associated petroleum gas and gas condensate in high-quality gasoline and other valuable products.
Processing of associated petroleum gas and gas condensate in high-quality gasoline and other valuable products possible with the help of mobile automated installations with a catalytic nanostructured zeolite catalysts. This method allows not only to dispose of APG, but also greatly reduce the cost of production of motor gasoline, as well as economical use of oil reserves.
Processing of associated petroleum gas and gas condensate in high-quality gasoline and other valuable products possible with the help of automated installations with a catalytic nanostructured zeolite catalysts. This method allows not only to solve relevant today for the oil and gas industry the problem of APG utilization, but also greatly reduce the cost of production of motor gasoline, as well as economical use of oil reserves.
If the oil straight-run gasoline fraction contains a maximum of 10-15%, in gas condensate up to 80% or more. For example, if you want to get 10 thousand tons of high octane (premium) gasoline, you will need to process approximately 100,000 tons of oil. While gas condensate to obtain the same volume of production will require about 15 thousand tons, that allows to save essentially on raw materials.
Gas condensate contains mainly fraction, suitable for producing high quality gasoline. However, gas condensate and APG significantly more difficult to process than the same oil. The fact that molecules of methane and ethane, are included in their composition, are chemically inert — virtually no interaction with other molecules. Therefore, associated gas and gas condensate are difficult in something to convert. In this regard, associated petroleum gas in most cases because of the lack of appropriate infrastructure, burned many oil fields and refineries for commercial purposes.
However, using modified nanostructured zeolite catalysts, gas condensates and associated gas can be processed into various valuable products.
An important feature of nanostructured zeolite catalysts (in contrast to the existing industrial metal, oxide and others) is that they have vysokonapornoj microporous structure. The diameter of such pores is equal to 6 – 8 Angstrom (1×10 -8 meters). In size they are comparable with such “small” molecules like ethane, propane, butane, and others, contained in associated petroleum gas and condensate. The inside of each of the micropores located supercolonies active centers. Getting into these narrow micropores, molecules are the most chemically inert of organic compounds are isolated and under the influence of supercolony centres acquire increased mobility and reactivity, which allows much easier and at a lower energy cost to expose them to various chemical reactions, forming with them a variety of valuable products.
Processing of gas condensate and associated petroleum gas with such catalysts at a special catalytic systems. Entering the reactor of this installation, naphtha condensate or gaseous fraction C2-C4 APG is first heated to a certain temperature, and then reacts with the catalysts (zeolites) and modifiers (oxide system). As a result of all these complex chemical processes scientists are getting lower olefins, arenas or vysokooktanovye liquid gasoline class “Euro 5” and “Euro 6”.
Such plants are fully automated and mobile, they can be used directly on the fields.
– low cost processing and utilization of associated petroleum gas and gas condensate
– maintaining the heat balance on the Earth,
– full automation of all processes.
