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.
  • This external pre-cooling refrigeration system has the disadvantage of significantly increasing the complexity of the liquefaction process since an additional refrigerant system with all its associated equipment is introduced.
  • the expander-based process may be a feed gas expander-based process.
  • the feed gas expander-based process may be an open loop feed gas process where the recycling loop comprises a warm-end expander loop and a cold-end expander loop.
  • the warm-end expander may discharge a first cooling stream and the cold-end expander may discharge the second cooling stream.
  • the temperature of the first cooling stream is higher than the temperature of the second cooling stream.
  • the pressure of the first cooling stream is higher than the pressure of the second cooling stream.
  • 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.
  • the first heat exchanger 612 may be an air cooled heat exchanger or a water cooled heat exchanger.
  • the cooled intermediate pressure gas stream 614 may then be compressed within a second compressor 616 to form a high pressure gas stream 618.
  • the pressure of the high pressure gas stream 618 may be greater than 2,000 psia (13,790 kPA), or more preferably greater than 3,000 psia (20,680 kPA).
  • the high pressure gas stream 618 may flow through a second heat exchanger 620 where the high pressure gas stream 618 is cooled by indirectly exchanging heat with the environment to form a cooled high pressure gas stream 622.
  • the second heat exchanger 620 may be an air cooled heat exchanger or a water cooled heat exchanger.
  • the cooled high pressure gas stream 622 may then be expanded within an HPCE expander 624 to form a chilled pretreated gas stream 626.
  • the pressure of the chilled pretreated gas stream 626 is less than 3,000 psia (20,680 kPA), or more preferably less than 2,000 psia (13,790 kPA), and where the pressure of the chilled pretreated gas stream 626 is less than the pressure of the cooled high pressure gas stream 622.
  • the second compressor 616 may be driven solely by the shaft power produced by the expander 624, as represented by the dashed line 628.
  • the second recycle gas stream 682 may be combined with the first warm stream 642 and, together, may be compressed in third and fourth recycle gas compressors 684, 686 and may exchange heat with the environment in a third recycle heat exchanger 688 to form the recycle refrigerant gas stream 604.
  • the third recycle gas compressor 684 may be driven solely by the shaft power produced by the first expander 636, as shown by the dashed line 690.
  • the fourth recycle gas compressor 686 may be driven solely by the shaft power produced by the second expander 644, as shown by the dashed line 692.
  • FIG. 7 illustrates a method 700 of producing LNG according to disclosed aspects.
  • a natural gas stream may be provided from a supply of natural gas.
  • the natural gas stream may be compressed in at least two serially arranged compressors to a pressure of at least 2,000 psia to form a compressed natural gas stream.
  • the compressed natural gas stream may be cooled to form a cooled compressed natural gas stream.
  • the cooled compressed natural gas stream may be expanded in at least one work producing natural gas expander to a pressure that is less than 3,000 psia and no greater than the pressure to which the at least two serially arranged compressors compress the natural gas stream, to thereby form a chilled natural gas stream.
  • the chilled natural gas stream may be liquefied.
  • Disclosed aspects may include any combinations of the methods and systems shown in the following numbered paragraphs. This is not to be considered a complete listing of all possible aspects, as any number of variations can be envisioned from the description above.
  • the chilled natural gas stream is a first chilled natural gas stream, and further comprising separating the first chilled natural gas stream into a second chilled natural gas stream, a first refrigerant stream, and a second refrigerant stream.
  • cooling the compressed natural gas stream comprises cooling the compressed natural gas stream in at least one heat exchanger that exchanges heat with the environment.
