Abstract: A process is described for liquefaction of a hydrocarbon-rich stream, especially a natural gas stream, at least indirect heat exchange taking place between the hydrocarbon-rich stream to be liquefied and the refrigerant mixture of at least one refrigerant mixture circuit, and the refrigerant mixture being separated after completed supercooling into a gaseous fraction and a liquid fraction and these fractions being recombined before and/or during the reheating of the refrigerant mixture. According to the invention, a gas fraction ( 9 ) that is identical or similar in composition is added at least from time to time to the gas fraction ( 4 ) that has been obtained in the separation (D). In doing so, the addition of the gas fraction ( 9 ) that is identical or similar in composition takes place when a minimum amount of the gas fraction ( 4 ) obtained in the separation (D) of the refrigerant mixture is not reached.

Abstract: In the liquefaction of a hydrocarbon by indirect heat exchange with the refrigerant mixture of a refrigerant mixture cycle, the refrigerant mixture being compressed in multiple stages, the compressed refrigerant mixture (23) is at least partially condensed (E4) downstream of the penultimate compressor stage and is fractionated (D4) into a higher-boiling liquid fraction (26) and a lower-boiling gas fraction (24). The lower-boiling gas fraction (24) is compressed to the final pressure, partially condensed (E5) and fractionated (D5) into a lower-boiling gas fraction (10) and a higher-boiling liquid fraction (27). The higher-boiling liquid fraction (27) is added to the partially condensed refrigerant mixture stream (23), and the gas fraction (10) forms the lower-boiling refrigerant mixture fraction and the liquid fraction (26) forms the higher boiling refrigerant mixture fraction of the refrigerant mixture cycle. Alternatively, the compressed refrigerant mixture (20, 31, 34) can be partially condensed (E3, E4, E5) after each compressor stage and fractionated in each case into a lower-boiling gas fraction (21, 32, 10) and a higher-boiling liquid fraction (30, 33, 35). Only the gas fraction (21, 32) from the partial condensation (E3, E4) in each case is further compressed and the liquid fractions (33, 35) from the second fractionation (D4, D5) are added to the partially condensed stream (20) from the first compressor stage upstream of its fractionation (D3). The gas fraction (10) from the final fractionation (D5) forms the lower-boiling refrigerant mixture fraction and the liquid fraction (30) from the first fractionation (D3) forms the higher-boiling refrigerant mixture fraction of the refrigerant mixture cycle.

Abstract: A process for liquefying a flow of natural gas with simultaneous recovery of a C 3 /C 4 -rich fraction is described, whereby the liquefaction of the flow of natural gas is carried out in heat exchange for at least one refrigerant and/or mixed refrigerant flow, and the flow of natural gas that is to be liquefied, after precooling, is subjected to a rectifying column, in which higher hydrocarbons are separated from the flow of natural gas, and then is subjected to further cooling and liquefaction, whereby a C 2+ -rich fraction that is recovered in the subsequent cooling of the flow of natural gas is fed to the rectifying column as a reflux liquid. According to the invention, a C 4 /C 5 -rich fraction ( 20, 35 ) is fed directly and/or indirectly to rectifying column (T 1 ) as an additional reflux liquid, whereby the feed point of the C 4 /C 5 -rich [fraction ( 20, 35 ) is located at the top of rectifying column (T 1 ) or is identical to the feed point of the C 2+ -rich fraction ( 5 ).]

Abstract: The invention relates to a method for compressing a multi-constituent flow, particularly a coolant mixture flow whereby, before compression, the multi-constituent flow is, inside a separating device, freed from liquid possibly contained in the multi-constituent flow to be compressed. According to the invention, a partial flow (5, 6, 8) of the compressed multi-component flow (3, 4) is fed at least occasionally to the separating device (D). The partial flow (5, 6, 8) fed to the separating device (D) can be diverted from the compressed multi-component flow (3, 4) before and/or after being subjected to a cooling (E) that ensues after compression (V).
