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.

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 method includes:



recovering and compressing a head stream coming from a separation column, to form a stream of compressed purified natural gas;
liquefying the stream of compressed purified natural gas in a liquefaction unit to form a stream of a pressurized liquefied natural gas;
flash expanding of the stream of pressurized liquefied natural gas and recovering in a storage;
recovering and compressing of a flow of flash gas coming from the expanding;
separating the flow of compressed flash gas (132) into a fuel stream and a recycle stream;
cooling and expanding the recycle stream, then introducing the cooled and expanded recycle stream at a head stage of the separation column.
