    • A device (4) [and a method] for changing the compression ratio of a reciprocating compressor (3) comprising a plurality of compression chambers (2i) pneumatically connected between an inlet port (40) and an outlet port (50), wherein a plurality of commutation valves (V) is provided for changing the number of compression steps, said valves arranged to switch [caused to switch] from a first to a second open/closed state combination, or vice-versa, wherein a lower number and a higher number, and vice-versa, respectively, of the compression chambers (2i) comprises chambers serially connected to one another, so that a gas to be compressed (8) is subjected to a number of compression steps that increases when switching from the first to the second combination, and decreases when switching in the opposite direction. Moreover, a control unit (60) is provided that is configured to [steps are provided of] receiving pressure signals (451,46N) upstream and downstream of the reciprocating compressor (3), respectively, to [of] computing the corresponding pressure ratios, to [of] generating opening/closing control signals (47) responsive to the pressure ratios, and to [and of] transferring the control signals to actuators of the commutation valves (V). In an application, the gas to be compressed (8) is withdrawn from a closed space (80), typically a compression facility of a gas pipeline, from which the gas has to be evacuated from an initial pressure (Psc,0) to a final pressure (P*) and, once compressed, is sent into a reception space (90), typically the gas pipeline itself, which is at a working pressure (Pe) that remains substantially unchanged during the evacuation. By the invention, it is possible to drastically reduce the emissions of harmful/valuable gas, which are currently released or burnt into the environment, during such evacuation operations.

    • A method for removing acidity and/or moisture from a hydrocarbon gas, in particular from a natural gas or a refinery gas fraction or a syngas, by absorption into a sweetening liquid and into a dehydration liquid, that are adapted to extract acid compounds or water from the gas, respectively. The method provides a step of prearranging a vertical elongated 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 series 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 parallel-mode is actuated when the flowrate of the gas rises above a maximum threshold value. An apparatus comprising at least such a container and a gas convey selective convey means (44',44"), for actuating said treatment modes, in particular responsive to a flowrate of the gas. The apparatus and the method according to the invention allow to maintain 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.
