One aspect of the invention relates to a hydrocarbons fluid liquefaction system, having a first heat-exchange module having a pre-cooling exchanger having a pre-cooling circuit and a plurality of pre-cooling refrigerant circuits for pre-cooling the feed stream through the circulation of an expanded first mixed-refrigerant stream, and a second heat-exchange module having a liquefaction exchanger having a liquefaction circuit and a liquefaction refrigerant circuit for liquefying the feed stream through the circulation of an expanded second mixed-refrigerant stream, wherein each heat-exchange module has thermally insulating walls and a framework that allows the module to be transported and secured, and allows the first heat-exchange module to be stacked on top of the second heat-exchange module.

Hydrocarbon fluid liquefaction system installation and system therefor

A method for producing liquefied natural gas and a stream of liquid nitrogen including step a): producing gaseous nitrogen in an air separation unit; step b): liquefying a stream of natural gas in a natural gas liquefaction unit including a main heat exchanger and a system for producing cold; step c): liquefying the nitrogen stream resulting from step a) in the main exchanger of the natural gas liquefaction unit in parallel with the liquefied natural gas in step b); wherein all the cold necessary for liquefying the stream of nitrogen and for liquefying the natural gas is supplied by the system for producing cold of the natural gas liquefaction unit.

Method for liquefying natural gas and nitrogen

In a process for vaporizing a liquid stream rich in carbon dioxide wherein a liquid first stream rich in carbon dioxide is withdrawn from a chamber containing liquid rich in carbon dioxide and gas rich in carbon dioxide, the gas being at a pressure P, the liquid first stream is sent to a heat exchanger where it is vaporized, all the liquid from the first stream is vaporized in the heat exchanger at a pressure or several pressures greater than P, the vaporized first stream is extracted from the heat exchanger, expanded in a first expansion valve and sent to the heat exchanger where it is heated.

Method and apparatus for vaporising carbon dioxide-rich liquid

A plant for purifying a gas stream comprising at least 0.02% by volume of water, COand NOx, comprising an adsorber characterized by:
