Abstract (en)

[origin: WO2006087520A1] A process for the conditioning of liquefied natural gas comprising the following steps: supplying (3) a feed stream of liquefied natural gas at a pressure in the range of from 15 to 35 barg to a heat exchanger (4) to produce an at least partially vaporized natural gas stream (5) ; passing at least part of the stream from step (i) to a distillation vessel (11) operated without reflux to produce a natural gas liquids stream (12) and a stream rich in methane (13) ; passing the stream rich in methane from step (ii) , without additional compression, to a heat exchanger (4) and cooling by heat exchange with at least part of the feed stream of liquefied natural gas to produce a liquid natural gas stream (14) ; vaporizing (18) the liquid natural gas stream from step (iii) to produce a conditioned natural gas; and recovering the natural gas liquids (12) .
