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.

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: A method for producing an LNG from natural gas, comprising



liquefaction of at least a first part of the natural gas in a first heat exchanger by heat exchange with a first mixed refrigerant fluid in a closed cycle,
sub-cooling of liquefied natural gas in a second heat exchanger by heat exchange with a second refrigerant fluid of a second refrigeration cycle,
expansion of the sub-cooled liquefied natural gas stream and admission into a flash gas separator,
withdrawal of liquefied natural gas at the bottom of the separator, and withdrawal, at the head, of a gas flow, and supply of the second refrigeration cycle by at least a part of said gas flow.

Abstract: The process comprises the following steps: mixing a gaseous stream of flash gas and a gaseous stream of boil-off gas to form a mixed gaseous flow; compressing the mixed gaseous flow in at least one compression apparatus to form a flow of compressed combustible gas; withdrawing a bypass flow in the flow of compressed combustible gas; compressing the bypass flow in at least one downstream compressor; cooling and expanding the compressed bypass flow; reheating at least a first stream derived from the expanded bypass flow in at least one downstream heat exchanger, reintroducing the first reheated stream in the mixed gaseous flow upstream from the compression apparatus.
