Abstract: A method for vaporizing a liquid stream includes cycling a heat transfer fluid in a closed circuit; feeding the heat transfer fluid to a first heat transfer zone; feeding a liquid stream to be vaporized to the first heat transfer zone; providing heat from the heat transfer fluid to the liquid stream in the first heat transfer zone thereby vaporizing the liquid stream and at least partially condensing the heat transfer fluid; removing the vaporized liquid stream and the at least partially condensed heat transfer fluid and passing the latter to a second heat transfer zone; providing heat from ambient air to the at least partially condensed heat transfer fluid thereby vaporizing the heat transfer fluid; recycling the vaporized heat transfer fluid to the first heat transfer zone using gravitational force exerted on the heat transfer fluid being cycled in the closed circuit.

Abstract: A gas turbine system comprises a gas turbine having a low pressure compression stage and a high pressure compression stage, a combustion chamber, and an expansion stage connected to the combustion chamber. The low pressure compression stage and the high pressure compression stage are connected with each other via an intercooling stage, wherein the low pressure compressed air stream from the low pressure compression stage is chilled to an intercooling temperature that is lower than the ambient temperature of the air source from which the air stream was supplied to the low pressure compression stage of the gas turbine.

Abstract: 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 (45) of a first gas turbine (50) is cooled using cooling duty from the main refrigerant in the main refrigerant circuit (200) to provide a cooled air inlet stream (55) to the first gas turbine (50).

Abstract: Method and apparatus for liquefying a hydrocarbon stream such as natural gas from a feed stream. The method comprises at least the steps of: first cooling the feed stream (10) against a first cooling refrigerant being cycled in a first cooling refrigerant circuit (100), wherein the first cooling refrigerant comprises >90 mol % propane, second cooling the cooled gas stream (20) to obtain a liquefied stream (60) against a first mixed refrigerant being cycled in a first mixed refrigerant circuit (200), wherein said second cooling is in two or more heat exchangers (42, 44), at least two of which are operating at different pressures and sub-cooling the liquefied stream (60) against a second mixed refrigerant or against a nitrogen refrigerant being cycled in a sub-cooling refrigerant circuit (300), thereby obtaining a sub-cooled hydrocarbon stream (70).

Abstract: Method of, and an apparatus for the removal of a sorbate component from a process stream comprising one or more sorbate components. Sorbate component(s) are captured using a sorbent. The loaded sorbent (200, 206, 228) is regenerated using solar thermal energy collected in a concentrated solar power system (10).
