Definitions

  • expansion device refers to one or more devices suitable for reducing the pressure of a fluid in a line (for example, a liquid stream, a vapor stream, or a multiphase stream containing both liquid and vapor). Unless a particular type of expansion device is specifically stated, the expansion device may be (1) at least partially by isenthalpic means, or (2) may be at least partially by isentropic means, or (3) may be a combination of both isentropic means and isenthalpic means.
  • the volumetric flow rate of the vaporized refrigerant of the SMR process can be more than 25% less than that of an conventional SMR process receiving warm pretreated gas.
  • the lower volumetric flow of refrigerant may reduce the size of the main cryogenic heat exchanger and the size of the low pressure mixed refrigerant compressor.
  • the lower volumetric flow rate of the refrigerant is due to its higher vaporizing pressure compared to that of a conventional SMR process.
  • the intermediate temperature pinch-point 208 occurs where the second cooling stream, typically the warm cooling stream, enters the heat exchanger.
  • the warm temperature pinch-point 210 occurs where the cold and warm cooling streams exit the heat exchanger.
  • the warm temperature pinch-point 210 causes a need for a high mass flow rate for the warmer cooling stream, which subsequently increases the power demand of the expander-based process.
  • One proposed method to eliminate the warm temperature pinch-point 210 is to precool the feed gas with an external refrigeration system such as a propane cooling system or a carbon dioxide cooling system.
  • an external refrigeration system such as a propane cooling system or a carbon dioxide cooling system.
  • United States Patent No. 7,386,996 eliminates the warm temperature pinch-point by using a pre-cooling refrigeration process comprising a carbon dioxide refrigeration circuit in a cascade arrangement.

  • the cold- end expander discharges a two-phase stream that is separated into a second cooling stream and a second pressurize LNG stream.
  • the combination of the HPCE process with the feed gas expander-based process has several advantages over a conventional feed gas expander-based process. Including the HPCE process therewith may increase the efficiency of the of the feed gas expander-based process by 20 to 25%.
  • the feed-gas expander process of this invention has an efficiency approaching that of an SMR process while still providing the advantages of no external refrigerant use, ease of operation, and reduced equipment count.
  • the refrigerant flow rates and the size of the recycle compressors are expected to be significantly lower for the exapander-base process combined with the HPCE process. For these reasons, the production capacity of a single liquefaction train according to disclosed aspects may be greater than 50% above the production capacity of a similarly sized conventional expander-based liquefaction process.
  • the intermediate pressure gas stream 610 may flow through a first heat exchanger 612 where the intermediate pressure gas stream 610 is cooled by indirectly exchanging heat with the environment to form a cooled intermediate pressure gas stream 614.

Abstract

La présente invention concerne un procédé de production de gaz naturel liquéfié (GNL). Un flux de gaz naturel est fourni depuis une alimentation en gaz naturel. Le courant de gaz naturel est comprimé dans au moins deux compresseurs (102, 112) agencés en série à une pression d'au moins 138 bars (2 000 psia) de sorte à former un flux de gaz naturel comprimé (114). Le flux de gaz naturel comprimé est refroidi (116) pour former un flux de gaz naturel comprimé refroidi (118). Le flux de gaz naturel comprimé refroidi est dilaté dans au moins un détendeur (120) de gaz naturel de production de travail à une pression inférieure à 207 bars (3 000 psia) et inférieure ou égale à la pression à laquelle lesdits deux compresseurs agencés en série compriment le flux de gaz naturel, pour former ainsi un flux de gaz naturel réfrigéré (122). Le flux de gaz naturel réfrigéré est liquéfié.
