METHOD OF PURIFICATION OF THE ASSOCIATED PETROLEUM GASES Russian patent published in 2006 - IPC B01D53/04 B01D53/26 

FIELD: petroleum industry; methods of purification of the associated petroleum gases.

SUBSTANCE: the invention is pertaining to the field of petroleum industry and may be used for the additional purification of the associated petroleum gas on the oil fields at its usage as the motor fuel. The method provides for adsorption of the moisture and hydrocarbon components by the sorbent with its subsequent regeneration. As the sorbent they use basalt fibers with the diameter of the elementary fiber of 5-8 microns, the length - of no more than 50 mm, the bulk density of 40-50 kg/m³ and the strength at the loading of 4-8 kN/m². Adsorption is realized at the temperature of 18-30°C. Regeneration of the sorbent is exercised in two stages: at the first stage the regeneration is conducted in the self-flowing mode of the adsorption components, and at the second stage the regeneration is run in the drying cabinet at the temperature of 180-200°C. The invention allows to increase effectiveness of purification of the petroleum gas.

EFFECT: the invention ensures the increased effectiveness of the petroleum gas purification.
