Definitions

  • FIG. 9 is a similar embodiment to that of FIG. 8 but using split expanded streams through the sub-cooler wherein an expansion valve, Joules- Thompson valve, or similar expansion device is used for improved efficiency in the sub-cooler.
  • FIG. 10 is another embodiment in which a nitrogen rejection stage has been integrated for situations in which nitrogen rejection may be needed.
  • the present method is any of the other embodiments disclosed herein further comprising providing cooling using a closed loop (e.g., sub-cooling loop 6) charged with flash vapor resulting from the LNG production (e.g., flash vapor 16).
  • a closed loop e.g., sub-cooling loop 6
  • flash vapor resulting from the LNG production e.g., flash vapor 16
  • first and second work expansion cycles are utilized for improved efficiency as follows: before feed gas stream 10 enters heat exchange area 57, side stream lib is taken from feed gas stream 10. After feed gas stream 10 exits heat exchange area 57, but before it enters heat exchange area 58, side stream lie is taken from feed gas stream 10. Thus, side streams lib and lie are taken from feed gas stream 10 at different stages of feed gas stream cooling. That is, each side stream is withdrawn from the feed gas stream at a different point on the cooling curve of the feed gas such that each successively withdrawn side stream has a lower initial temperature than the previously withdrawn side stream.
  • Expander 35 may be any type of liquid expander or hydraulic turbine. Expander 35 is placed between heat exchange areas 58 and 59 such that feed gas stream 10 flows from heat exchange area 58 into expander 35 where it is expanded, and consequently cooled to produce expanded feed gas stream 10b. Stream 10b then is passed to heat exchange area 59 where it is sub-cooled to produce sub-cooled stream 10c. By expanding and consequently cooling feed gas stream 10 in expander 35 to produce stream 10b, the overall cooling load on sub-cooling loop 8 is advantageously reduced.
  • the present method comprises providing supplemental cooling for the feed gas stream from a plurality of work expansion devices, each of the work expansion devices expanding a portion of the feed gas stream and thereby cooling the portion to form one or more expanded, cooled side streams, wherein each of the portions of the feed gas stream expanded in the work expansion devices is withdrawn from the feed gas stream at a different stage of feed gas stream cooling (i.e., at a different feed gas stream temperature); and cooling said feed gas stream by indirect heat exchange with said one or more expanded, cooled side streams.
  • the present method is any of the other embodiments described herein further comprising compressing the feed gas stream to any of the pressures described above to produce a pressurized feed gas stream; feeding the pressurized feed gas stream to a work expansion device, or to a plurality of work expansion devices; expanding the compressed feed gas stream through the work expansion device, or through a plurality of work expansion devices, to provide supplemental cooling for the feed gas stream.
  • FIG. 9 depicts an embodiment for use with certain feed gas 10 compositions and/or pressures.
  • an expansion valve 82 or other expander e.g., a Joules-Thompson valve
  • FIG. 10 represents another embodiment showing the integration of a nitrogen rejection stage using distillation column 81 or equivalent device, for the case where nitrogen rejection is needed, based on feed gas 10 composition. This may be needed to meet the nitrogen specification of product LNG for transmission and end use.
  • FIG. 11 represents another embodiment showing the integration of a nitrogen rejection unit, where the flash vapor from the nitrogen rejection unit is used as refrigerant for the sub-cooling loop.
  • the resulting refrigerant is therefore rich in nitrogen.

Abstract

L'invention concerne, selon des modes de réalisation, un procédé de liquéfaction de gaz naturel et autres flux gazeux riches en méthane, et plus particulièrement, un processus de production de gaz naturel liquéfié (GNL). Dans une première étape du processus, une première fraction du flux gazeux est retirée, comprimée à une pression supérieure ou égale à 1500 psia, refroidie puis dilatée à une pression inférieure afin de refroidir ladite première fraction retirée. La fraction restante du flux gazeux est refroidie par échange thermique indirect avec la première fraction dilatée, dans un premier processus d'échange thermique. Dans une seconde étape, un flux séparé comprenant de la vapeur instantanée est comprimée, refroidie puis dilatée à une pression inférieure afin de produire un autre flux froid. Ce flux froid est utilisé pour refroidir le flux gazeux d'alimentation restant, dans un second processus d'échange thermique. Le flux dilaté résultant du second processus d'échange thermique est utilisé pour réaliser un refroidissement supplémentaire dans la première étape d'échange thermique indirect. Le gaz d'alimentation restant est subséquemment dilaté à une pression inférieure pour liquéfier partiellement le flux gazeux d'alimentation. La fraction liquéfiée de ce flux est retirée du processus en tant que GNL dont la température correspond à la pression de point de bulle.
