Abstract
An apparatus for use on board ship to reliquefy a compressed vapor employs pre-assemblies of components. The reliquefaction is effected in a closed cycle in which a working fluid is compressed in at least one compressor, is cooled in a first heat exchanger, is expanded in a turbine and is warmed in a second heat exchanger in which the compressed vapor is at least partially condensed. The apparatus comprises a first pre-assembly including the second heat exchanger and a second pre-assembly including the first heat exchanger, the compressor and the expansion turbine are positioned. The pre-assemblies are positioned on respective platforms.
Claims10
An apparatus which when assembled is operable to reliquefy a compressed vapour by a method comprising performing an essentially closed refrigeration cycle comprising compressing a working fluid in at least one compressor, cooling the compressed working fluid by indirect heat exchange in a first heat exchanger, expanding the cooled working fluid in at least one expansion turbine, warming the expanded working fluid by indirect heat exchange in a second heat exchanger, and returning the warmed expanded working fluid through the first heat exchanger to the said compressor, and at least partially condensing the compressed vapour in the second heat exchanger, wherein the apparatus comprises a first support platform on which a first pre-assembly including the second heat exchanger is positioned and a second support platform on which a second pre-assembly is positioned, characterised in that the said compressor, the said expansion turbine and the first heat exchanger are all included in the second pre-assembly.
