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 for removing contaminants from a natural gas feed stream including water and sour species, 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 first liquefied hydrocarbon stream (10) is provided from a first source (12) and a second liquefied hydrocarbon stream (20) is provided from a second source (22). The second liquefied hydrocarbon stream (20) has been liquefied solely by cooling against a first cooled nitrogen-based stream (40). The first and second liquefied hydrocarbon streams (10,20) are gasified to produce a gasified hydrocarbon stream (11,21,51), thereby cooling a gaseous nitrogen-based stream (30) against the gasifying first and second liquefied hydrocarbon streams (10,20) to provide a second cooled nitrogen-based stream (40).
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 the heat transfer fluid is recycled in step g) using gravitational force exerted on the heat transfer fluid being cycled in the closed circuit (4).
