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 liquefying a stream rich in hydrocarbons, especially a stream of natural gas, by the indirect exchange of heat with the refrigerants in a closed-circuit cascade of mixed refrigerants. According to the invention, said closed-circuit cascade of mixed refrigerants consists of at least 3 circuits of mixed refrigerants, with each circuit comprising different refrigerants. The first of the three mixed refrigerant circuits is used for pre-cooling (E1), the second for liquefying E2), and the third for super-cooling (E3) the hydrocarbon-rich stream (1) to be liquefied. The method provided for in the invention reduces specific energy consumption and investment costs since the three circuits of mixed refrigerants are or can be optimally adjusted to the enthalpy temperature curves of the hydrocarbon-rich stream to be liquefied and the refrigerant mixtures.

Abstract: Method for liquefying a hydrocarbon-rich stream, especially a natural gas stream, comprises separating a first coolant mixture cycle (1-12) into a low boiling fraction (10) and a higher boiling fraction (2). The two fractions have different pressures and are fed to a pre-cooling unit (E1). Preferred Features: Pre-cooling of the hydrocarbon-rich stream is carried out in a wound heat exchanger. A second coolant mixture cycle (20-25) has a compressor (V2) with a pressure ratio of at least 10.

Abstract: The air feed (1) for a gas turbine (T) is initially passed through a quench cooler (Q), where its temperature is reduced by a coolant medium (7) and preferably water. The quench cooler has a number of bases and/or at least one packing, to bring the air temperature of 15-50degreesC down to 4-15degreesC. The coolant water recirculates in a circuit (7-10), with a pump (P) and a heat exchanger (E).
