    摘要： A gaseous hydrocarbon stream (10) is cooled against a first refrigerant and a second refrigerant, to produce a liquefied hydrocarbon stream (20). The first refrigerant is cycled in a first refrigerant circuit (100), comprising compressing in a first compressor train (110) comprising one or more first compressors on a common drive shaft (215). The second refrigerant is cycled in a second refrigerant circuit (200), comprising compressing in a second compressor train (210) comprising one or more second compressors on said common drive shaft (215). The common drive shaft (215) is driven with one single gas turbine (220). The single gas turbine (220) is a multiple shaft gas turbine with a shaft power for mechanical drive of at least 40 MW, comprising at least one auxiliary turbine (180) and at least one inlet air compressor (160) mechanically connected to the auxiliary turbine (180) via a first internal shaft (22), and a power turbine (190) drivingly engaged with the common drive shaft (215), which power turbine (190) is separately rotatable from the first internal shaft (22).

    摘要： The invention relates to a method for drying gases, wherein the gas is conducted through two or more than two gas coolers connected in series, wherein each of said coolers is fed a stream of solvent that withdraws water from the gas entering the respective cooler, wherein a mixed stream consisting of gas and solvent then enters each of said gas coolers and is then conducted through the respective cooler and, following joint cooling in the respective cooler, is separated by means of a gas/liquid separator associated with the respective cooler in the outlet into a gas stream having a reduced water content and a solvent stream loaded with water, wherein the water content of the gas decreases successively from the first cooler in the flow direction down to the last cooler in the flow direction, and each separated solvent stream loaded with water is either used as a feed stream for the cooler connected upstream or is recirculated directly into the solvent regeneration device, in which the solvent enriched with water is freed of water again, and the gas outlet temperature of a cooler connected downstream in the flow direction is lower than that of the cooler located upstream the same in the flow direction.

    摘要： Method and apparatus for cooling a hydrocarbon stream (520) to produce an at least partially liquefied hydrocarbon stream (530). A cooled main refrigerant stream (245) is further cooled against at least a part of one or more expanded cooled pre-cooling refrigerant streams (155). A hydrocarbon stream (520) is at least partially liquefied in one or more main heat exchangers (220) against an expanded cooled main refrigerant stream (255), to provide an at least partially, preferably fully, liquefied hydrocarbon stream (530). The air inlet stream (45a) of a first gas turbine (50a) is cooled using cooling duty from the main refrigerant in the main refrigerant circuit (200) to provide a cooled air inlet stream (55a) to the first gas turbine (50a).

    摘要： A method and associated system for regulation of the cooling capacity of a cooling system that uses a gas expansion cooling circuit where the cooling principle is expansion of one or more gaseous cooling medium streams from a higher pressure to a lower pressure are described, characterised by the following steps: —reducing the amount of cooling medium which is circulated in the cooling circuit (100) temporarily in that a fraction of gaseous cooling medium is pre-cooled at a higher pressure and is extracted from the cooling circuit (100), —expanding the fraction of cooled gaseous cooling medium across an expansion device (102) to a lower pressure so that at least one part of liquid cooling medium separates, —separating the liquid from the non-condensed gas for temporary storage in a storage unit (104) so that the liquid is temporarily not circulated in the otherwise closed cooling circuit (100), —thereafter to return temporarily stored gaseous cooling medium from the storage unit (104) to the cooling circuit (100) according to need, and—returning non-condensed gas and evaporated cooling medium from the storage unit (104) to a suitable location in the cooling circuit (100). A system to reduce the cooling capacity of a cooling installation based on gas expansion cooling, is also described.
