Abstract: A first liquefied hydrocarbon stream is provided from a first source and a second liquefied hydrocarbon stream is provided from a second source. The second liquefied hydrocarbon stream has been liquefied by cooling solely against a first cooled nitrogen-based stream. The first and second liquefied hydrocarbon streams are gasified to produce a gasified hydrocarbon stream, thereby cooling a gaseous nitrogen-based stream against the gasifying first and second liquefied hydrocarbon streams to provide a second cooled nitrogen-based stream.

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: 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).

Abstract: A process is described for removing contaminants from a natural gas feed stream including water. The process includes the steps of cooling the natural gas feed stream in a first vessel to a first operating temperature at which hydrates are formed, heating the hydrates to a temperature that is above the first operating temperature by introducing a warm liquid to the first vessel so as to melt the hydrates and liberate a dehydrated gas and a water-containing liquid, and removing from the first vessel a stream of dehydrated gas.

Abstract: The present invention relates to a method for vaporizing a liquid stream, the method at least comprising the steps of: a) feeding a heat transfer fluid to a first heat transfer zone (2), the heat transfer fluid being cycled in a closed circuit (4); b) feeding a liquid stream (20) to be vaporized to the first heat transfer zone (2); c) providing heat from the heat transfer fluid to the liquid stream across a heat transfer surface in the first heat transfer zone (2) thereby vaporizing the liquid stream and at least partially condensing the heat transfer fluid; d) removing the vaporized liquid stream (30); e) removing the at least partially condensed heat transfer fluid and passing it to a second heat transfer zone (3); f) providing heat from ambient air to the at least partially condensed heat transfer fluid across a heat transfer surface in the second heat transfer zone (3) thereby vaporizing the heat transfer fluid; g) recycling the vaporized heat transfer fluid to the first heat transfer zone (2); wherein th

Abstract: A method of cooling a hydrocarbon stream such as natural gas, the method at least comprising the steps of: (a) providing a feed stream; (b) passing the feed stream through a gas treatment stage comprising one or more (number: X) parallel gas treatment units, the feed stream being divided into two or more part-feed streams if there is more than one gas treatment unit, to provide one or more first treated streams; (c) passing the first treated stream or streams of step (b) through an NGL extraction stage comprising one or more (number: Y) parallel NGL extraction units, the first treated stream or streams being shared to match the number of NGL extraction units, to provide one or more second treated streams; and (d) passing the second treated stream or streams of step (c) through a cooling stage comprising one or more (number: Z) parallel cooling systems, the second treated stream or streams being shared to match the number of cooling systems, to provide a cooled hydrocarbon stream or streams.

Abstract: A process for removing contaminants from a natural gas feed stream including water and sour species is provided, which process comprises the steps of cooling the natural gas feed stream in a first vessel (12) to a first operating temperature at which hydrates are formed and removing from the first vessel (12) a stream of dehydrated gas (34); and cooling the dehydrated gas in a second vessel (14) to a second operating temperature at which solids of the sour species are formed or at which the sour species dissolve in a liquid and removing from the second vessel (14) a stream of dehydrated sweetened gas (62).

Abstract: A floating plant for liquefying natural gas having a barge provided with a liquefaction plant, member for receiving natural gas and with member for storing and discharging liquefied natural gas. The liquefaction plant involves a heat exchange in which heat is removed when liquefying natural gas is transferred to water. The barge is further provided with a receptacle; an open-ended water intake conduit having an inlet; a connecting conduit extending from the outlet of the water intake conduit to the receptacle; a pump for transporting water from the receptacle to the heat exchanger and a water discharge system for discharging water removed from the heat exchanger. The connecting conduit has the shape of an inverted “U” of which the top is located above the receptacle.
