摘要： This invention relates to a method for liquefying a gas containing at least 60 mol % of CO2, in order to produce at least one liquid product, wherein the gas is cooled in order to form a fluid flow, at least a portion of the liquid or supercritical flow is cooled in a heat exchanger in order to form a cycle fluid having a cycle pressure, the cycle fluid is divided into at least two fractions including an auxiliary fraction, one of the fractions being expanded up to a first pressure in a valve in order to form a biphasic mixture, and then sent to a phase separator. The liquid fraction of the phase separator is vaporized so as to form a vaporized gas in the exchanger, the vaporized gas then being expanded from the first pressure to a second pressure in an expansion means, and then compressed in the cycle compressor and mixed with the first feed gas.

摘要： The present invention relates to methods and a system for cooling a gas for the purpose of effecting the liquefaction of one or more components of this gas. The invention is more precisely concerned with the prevention of losses by evaporation from the tanks of methane-carrier ships during the transport of liquid methane. For this purpose, the evaporation leakages from the tanks in gaseous form are re-liquefied by ad hoc liquefaction apparatus aboard the ship. The apparatus utilizes a cascade frigorific cycle of the open type working with a single refrigerant having a plurality of components. The refrigerant comprises the pure substance to be re-liquefied, and at least one heavy component, less volatile than the said substance, and absent from the composition of the gas treated.

摘要： Process and installation for the compression and expansion of at least one gaseous stream, in which a first stream of a gaseous mixture is compressed in a compressor (5) having at least one compression stage (5A, 5B, 5C); a second stream of a gaseous mixture is supercharged in a supercharger (7); a third stream of a gaseous mixture is expanded in an expansion engine (9); at least a portion of the energy generated by the expansion engine is recovered with the supercharger (7) and at least a portion of the second supercharged stream is sent upstream of one stage (5B) of the compressor. The first and second streams are compressed in at least one stage (5A) of the compressor before sending the second stream to the supercharger. The second stream comes from upstream of one stage of the compressor and at least a portion of the supercharged second stream is returned downstream of this stage. The point of origin of the second stream and the point of return of this latter are separated by at least one compression stage. The first stream and the second stream are distilled, after compression, in a distillation apparatus, and the third stream is a gaseous product withdrawn from the apparatus.
