  • the heat medium warmer 18 receives a supply of seawater (for example, 5°C or higher) and the heat medium (-2°C or higher) and warms the heat medium by heat exchange with the seawater.
  • the heat medium warmer 18 is a plate-type heat exchanger provided with a titanium plate having excellent seawater corrosion resistance and abrasion resistance.
  • the plate-type heat exchanger is characterized by having high heat transfer properties.
  • the fluids are substantially equilibrium amounts and have a high heat transfer coefficient, a deviation is small depending on location, and sufficient heat exchange is possible with a temperature difference of 2°C between the fluids.
  • the seawater is input to a seawater inlet 18c of the heat medium warmer 18 by the seawater pump 20 and output from a seawater outlet 18d of the heat medium warmer 18.

  • the heat medium warmer 18 receives a supply of, for example, 7°C seawater and a -1°C heat medium (ethylene glycol aqueous solution with a freezing temperature of -23°C) to warm the heat medium to 5°C.
  • the heat medium warmed by the heat medium warmer 18 is supplied to the shell side inlet 16c of the warming heat exchanger 16 via the line 33.
  • the booster pump 14 pressurizes the -20°C, 1.97 MPa liquefied carbon dioxide to -20°C and 10.5 MPa.
  • the warming heat exchanger 16 warms the -20°C, 10.5 MPa liquefied carbon dioxide supplied to the tube side inlet 16a to 0°C (10.2 MPa) by heat exchange with the 5°C heat medium.

  • the configuration of the liquefied carbon dioxide warming equipment 10 according to the present embodiment has been described above. According to the liquefied carbon dioxide warming equipment 10 according to the present embodiment, since the liquefied carbon dioxide is warmed using seawater, costs can be reduced compared to a case in which a hot water boiler requiring fuel is used, and further, an extremely small amount of CO 2 is discharged.
  • a minimum temperature of seawater is 6°C to 8°C in winter on the Japan Sea side (4°C to 6°C in the northern sea).
  • the seawater may freeze in the heat exchanger, and the heat exchanger may be blocked. Therefore, by configuring heat exchange to be between the heat medium having a low freezing temperature and the liquefied carbon dioxide, such as in the liquefied carbon dioxide warming equipment 10 according to the present embodiment, blockages can be prevented in the heat exchanger.
  • the heat medium temperature controller 30 performs control so that the temperature of the heat medium input into the heat medium inlet 18a of the heat medium warmer 18 is equal to or higher than the freezing temperature of the seawater (about -2°C), freezing of the seawater does not occur in the heat medium warmer 18.
  • the liquefied carbon dioxide warming equipment 10 since the fluid supplied to the warming heat exchanger 16 has low corrosiveness, general steel can be used as a material instead of expensive titanium. As a result, the cost of the shell-and-tube warming heat exchanger 16 can be significantly reduced.
  • the heat medium warmer 18 is the plate-type heat exchanger provided with the titanium plate having excellent seawater corrosion resistance and abrasion resistance. While titanium is used due to its seawater corrosion resistance, since the thickness of the plate is as thin as 0.4 mm to 0.7 mm, the heat medium warmer 18 is inexpensive when compared to the shell-and-tube heat exchanger using titanium heat transfer tubes.
  • Fig. 3 is a view for describing liquefied carbon dioxide warming equipment 40 according to another embodiment of the present invention.

  • a case is considered in which a -20°C, 1.97 MPa liquefied carbon dioxide is pressurized and warmed to 0°C and 10 MPa.
  • the heat medium warmer 18 receives a supply of, for example, 7°C seawater and a -1°C heat medium (ethylene glycol aqueous solution with a freezing temperature of -23°C) to warm the heat medium to 5°C.
  • the heat medium warmed by the heat medium warmer 18 is supplied to the shell side inlet 16c of the warming heat exchanger 16 via the line 33.
  • the booster pump 14 pressurizes the -20°C, 1.97 MPa liquefied carbon dioxide to -20°C and 10.5 MPa.
  • the warming heat exchanger 16 warms the -20°C, 10.5 MPa liquefied carbon dioxide supplied to the tube side inlet 16a to 0°C (10.2 MPa) by heat exchange with the 5°C heat medium.
  • One part of the - 20°C, 1.97 MPa liquefied carbon dioxide is supplied to the shell side inlet 42c of the liquefied carbon dioxide vaporization heat exchanger 42.
  • the liquefied carbon dioxide vaporization heat exchanger 42 vaporizes the liquefied carbon dioxide supplied to the shell side inlet 42c by heat exchange with the 5°C heat medium supplied to the tube side inlet 42a and outputs the liquefied carbon dioxide from the shell side outlet 42d (-20°C, 1.97 MPa).
  • the outlet of the booster pump 14 is -46°C and 10.5 MPa
  • the shell side outlet 42d of the liquefied carbon dioxide vaporization heat exchanger 42 is -46°C and 0.80 MPa, and the temperature and pressure at the other portions are the same.
