Definitions

  • the present invention relates to a refrigerant circuit, in particular for use in a liquefaction plant.
  • a refrigerant circuit comprises a refrigerator (or ⁇ refrigeration zone' ) in which the refrigerant is evaporated in one or more stages thereby withdrawing heat from the gas stream to be cooled; a compressor for recompressing the evaporated refrigerant (s) ; and return lines for returning the recompressed refrigerant to the refrigerator.
  • the amount of cooling provided per unit of time in the refrigerator is proportional to the mass flow rate of the refrigerant that is passed through the refrigerator in the refrigerant circuit.
  • the mass flow rate of the refrigerant has to increase.
  • an increasing mass flow rate does not affect the number of impellers being present in the compressor, it has an effect on the size of the impellers, on the diameter of the housing, and on the inlet velocity into the impellers. Because the latter variables increase with increasing flow rate, an increasing flow rate will result in a larger compressor and higher inlet velocities.
  • increasing the diameter of the housing of the compressor requires a thicker wall of the housing. Consequently the compressor is more difficult to manufacture and more difficult to handle.
  • WO 01/44734 discloses a refrigerant circuit for use in a liquefaction plant, wherein the refrigerant circuit contains a compressing apparatus with two compressors, each compressor being arranged in a separate housing.
  • the compressing apparatus according to WO 01/44734 allows the handling of four different refrigerant streams being evaporated in a refrigerator at multiple pressure levels.
  • US 3 527 059 and US 6 691 531 disclose refrigerant circuits allowing to handle refrigerant streams evaporated at three different pressure levels.
  • a refrigerant circuit in particular for use in a liquefaction plant, the refrigerant circuit at least comprising: a refrigerator having an inlet for refrigerant at a refrigeration pressure, and at least five outlets for evaporated refrigerant evaporated at different pressure levels; - a first compressor having one or more inlets for receiving evaporated refrigerant from the refrigerator and an outlet that can be connected to the inlet of the refrigerator; and a second compressor having one or more inlets for receiving evaporated refrigerant from the refrigerator and an outlet that can be connected to the inlet of the refrigerator; wherein the at least five outlets are intended for refrigerants evaporated at at least four, preferably at least five, increasing pressures from the first outlet to the fifth and optional higher outlets.
  • An important advantage of the present invention is that it provides a surprisingly simple refrigerant circuit allowing the handling of five or more gaseous refrigerant streams evaporated at four or more, preferably five or more, different pressure levels in
  • a further advantage of the present invention is that each of the first and second or even further compressors can be separately protected against overpressure, e.g. by using relief valves or the like. This may reduce the size of the pressure relief system significantly.
  • Another advantage of the present invention is that evaporation of refrigerant at multiple pressure levels is more efficient; the present invention allows for evaporation at more than four different pressure levels.
  • the refrigerator may have various line-ups. According to a particularly preferred embodiment it allows refrigerant to evaporate at at least five different pressure levels. As the person skilled in the art understands what is meant by a refrigerator, this is not further discussed here.
  • the first and second compressors may be any suitable compressor. If desired, more than two compressors may be present. Also, the first and second (and even further) compressors may each comprise one or more compression stages .
  • the first compressor has a main inlet for receiving the refrigerant from the first outlet, a second inlet for receiving the refrigerant from the third outlet, a third inlet for receiving the refrigerant from the fifth outlet and an outlet that can be connected to the inlet of the refrigerator; and the second compressor has a main inlet for receiving the refrigerant from the second outlet, a second inlet for receiving the refrigerant from the fourth outlet and an outlet that can be connected to the inlet of the refrigerator.
  • the odd (i.e. first, third, fifth, seventh, ...) outlets are connected to the second compressor and the even (i.e. second, forth, sixth, eighth, ...) outlets are connected to the first compressor, wherein the pressure of the evaporated outlet increases from the first outlet to the fifth and optional higher outlet .
  • economizers may be connected to one or more of the outlets of the refrigerator.
  • economizers are known in the art (see e.g. John M. Campbell, "Gas Conditioning and Processing - Vol. 2: The Equipment Modules", 8th Edition edited by Robert A. Hubbard, 2004 page 219) this is not further discussed here.
  • the outlet of the refrigerator intended for the refrigerant evaporated at the highest pressure is connected to an economizer.
  • the present invention provides a plant for the production of a liquefied hydrocarbon product such as liquefied natural gas, the plant comprising the refrigerant circuit according to the present invention for cooling a hydrocarbon stream such as natural gas .
  • the present invention provides a method for cooling, preferably liquefying a hydrocarbon stream to be cooled, wherein the hydrocarbon stream to be cooled is cooled using the refrigerant circuit according to the present invention.
  • the hydrocarbon stream to be cooled and/or liquefied may be any suitable hydrocarbon-containing stream, but is usually a natural gas stream obtained from natural gas or petroleum reservoirs.
  • the natural gas may also be obtained from another source, also including a synthetic source such as a Fischer-Tropsch process.
  • the hydrocarbon stream is comprised substantially of methane (e.g. > 60 mol% methane) .
  • the hydrocarbon stream may contain varying amounts of hydrocarbons heavier than methane such as ethane, propane, butanes and pentanes as well as some aromatic hydrocarbons.
  • the hydrocarbon stream may also contain non-hydrocarbons such as H2O, N2, CO2, H2S and other sulphur compounds, and the like.
  • the hydrocarbon stream may be pre-treated before cooling.
  • This pre-treatment may comprise removal of undesired components such as H2O, CO2 and H2S, or other steps such as pre-cooling, pre-pressurizing or the like. As these steps are well known to the person skilled in the art, they are not further discussed here.
