Abstract: The method includes cooling and liquefying a feed gas stream, separating a stream obtained from the feed gas stream, and recovering a treated gas stream and a natural gas liquid stream. The method further includes compressing the treated gas stream in order to form a compressed treated gas stream, and fractionating the natural gas liquid stream into a plurality of hydrocarbon fractions (28, 30, 32, 33). The method additionally includes withdrawing from the compressed treated gas stream, of a recycle stream, and reintroducing the recycle stream without cooling into the feed gas stream, into the cooled feed gas stream, or into a stream obtained from the cooled feed gas stream upstream of an expander.

Abstract: A device comprises an assembly for attaching to and moving on the production line. The attachment and movement assembly comprises at least two clamps that can be actuated selectively to clamp the production line, the attachment and movement assembly comprising an active mechanism for moving the clamps longitudinally relative to each other. The attachment and movement assembly comprises a tilting mechanism for tilting the clamps relative to each other, between a position in which they are parallel to each other and a position in which they are tilted with respect to each other. The tilting mechanism comprises a flexion bar capable of switching from a straight configuration in the parallel position of the clamps to a curved configuration in the tilted position of the clamps.

Abstract: This method comprises passing a residual stream into a flash drum to form a gaseous overhead flow and liquid bottom flow, and feeding the bottom flow into a distillation column,
It comprises cooling the overhead flow in a heat exchanger to form a cooled overhead flow.
It comprises the extraction of a gaseous overhead stream at the head of the distillation column, and the formation of at least one effluent stream from the overhead stream and/or from the top stream.
The separation of the cooled overhead flow comprises passing the cooled overhead flow into an absorber, and injecting a methane-rich stream into the absorber to place the cooled overhead flow in contact with the methane-rich stream.-

Abstract: A clamp comprises a plurality of pads; a belt for clamping the pads that is maneuverable between an unclamped configuration and a configuration clamping the pads against the production line; a clamping actuator for the clamp, mounted on a first point of the clamp, the clamping actuator having a grasping member for a second point of the clamp, the grasping member being movable between a deployed position and a retracted position moving the second point towards the first point. The spacing-apart mechanism is able to move the grasping member between a spaced-apart configuration of the second point in the deployed position of the grasping member and a grasping configuration in an intermediate position between the deployed position and the retracted position.

Abstract: The method comprises supplying, at a construction site, of a functional module comprising a hybrid cooler; verifying onsite the exploitation of the equipment of the functional module; mounting the functional module on a support structure; moving the structure to an exploitation site on the expanse of water. The verification involves passing a flow to be cooled through the air cooler of the hybrid cooler, the flow being cooled exclusively by a flow of air circulating through the air cooler of the hybrid cooler. The exploitation of hydrocarbons on the expanse of water involves the passage of a flow to be cooled through the water cooler of the hybrid cooling system, the flow being cooled by heat exchange with water taken from the expanse of water circulating through the water cooler.
