摘要： A method and an apparatus (100) for reducing the pressure of a natural gas (2) at a wellhead of a natural gas field. The method provides prearranging an energy recovery expansion device (20), which comprises a stator and a rotor mechanically connected with a power generator (29), and a gas passageway between the rotor and the stator, and conveying the natural gas into the passageway of the energy recovery expansion device (24) to cause a rotation of the rotor and the expansion of the gas, the pressure being reduced from the extraction pressure (Pi) to the use pressure (Pa), which makes it possible to obtain an electric power (W) during the expansion, adapted to satisfy the energy requirements of the gas extraction unit, in particular of an offshore platform, without installing local electric generators. In order to allow a reliable operation of a recovery expansion device, such as a turbine, a means is provided for finely separating solid and liquid matter present in the gas, as well as a means (7) for conditioning the gas entering the expansion device, which may comprise a feeding means (12) of an additive into the gas (3), said additive adapted to decrease the formation temperature of the solid, and, in an advantageous way in case of higher amount of water, a means for heating the gas such that the temperature is maintained above the formation temperature of the solid.

The method provides prearranging an expansion device (20) comprising at least one first expansion equipment, selected from the group comprised of: a radial expansion device (19) and a static expansion device (24), in which a first expansion takes place with a cooling effect down to a temperature that is higher than the solid formation temperature that may be formed starting from water and/or hydrocarbons present in said gas, and further comprising at least one second expansion equipment, selected from the group comprised of: a static expansion device (30) and a screw expansion device (25), which is arranged downstream of the first expansion equipment (19, 24), and where the expansion continues with a further cooling effect below the solid formation temperature, such that ice and/or hydrocarbon hydrates are formed only in the second expansion equipment arranged downstream. This way, it is possible to obtain a liquefaction of the hydrocarbons with two or more carbon atoms by means of Joule-Thomson effect even if the combustible gas contains considerable amount of water, without resorting to expensive preliminary dehydration operations.

The method provides prearranging an expansion device (20) comprising at least one first expansion equipment, selected from the group comprised of: a radial expansion device (19) and a static expansion device (24), in which a first expansion takes place with a cooling effect down to a temperature that is higher than the solid formation temperature that may be formed starting from water and/or hydrocarbons present in said gas, and further comprising at least one second expansion equipment, selected from the group comprised of: a static expansion device (30) and a screw expansion device (25), which is arranged downstream of the first expansion equipment (19, 24), and where the expansion continues with a further cooling effect below the solid formation temperature, such that ice and/or hydrocarbon hydrates are formed only in the second expansion equipment arranged downstream. This way, it is possible to obtain a liquefaction of the hydrocarbons with two or more carbon atoms by means of Joule-Thomson effect even if the combustible gas contains considerable amount of water, without resorting to expensive preliminary dehydration operations.

摘要： A method for removing acidity and/or moisture from a hydrocarbon gas, in particular from a natural gas, a refinery gas or a syngas, by ab¬ sorption into a sweetening liquid and into a dehydration liquid, that are adapted to extract acid compounds or water from the gas, respec¬ tively. The method provides a step of prearranging a vertical elongat¬ ed container (150) comprising at least one inner partition wall (168) that defines at least two treatment chambers within said container (151,152), a step of feeding a treatment liquid from the above into at least one of the two chambers (251,252) and feeding the gas to be treated from below into at least one same treatment chamber. It is also provided a step of selecting a treatment mode, wherein the gas flows along the two treatment chambers in a parallel or in a se¬ ries arrangement, or one chamber being excluded; in particular the series-mode or the exclusion mode is actuated when the flowrate of the gas decreases below a minimum threshold value, while the paral¬ lel-mode is actuated when the flowrate of the gas rises above a max¬ imum threshold value. An apparatus comprising at least such a con¬ tainer and a gas convey selective convey means (44', 44") for actuat¬ ing said treatment modes, in particular responsive to a flowrate of the gas, is also described. The apparatus and the method allow to main¬ tain the sweetening and/or dehydration efficiency, in particular in the case of a progressive reduction of the flowrate of natural gas that can be obtained from a well or gasfield.
