A liquefied natural gas (LNG) regasification facility utilizes a vertical heat exchanger or vaporizer that consists of a shell with a single-pass tube bundle used to convert the fuel to its vapor form for subsequent delivery through a land-based pipeline. Pressurized LNG is off-loaded from an oceangoing tanker to the bottom of the vaporizer at Tc,i = -155°C and mLNG = 150 kg/s and flows through the shell. The pressurized LNG has a vaporization temperature of T = -75°C and specific heat Cp,l = 4200 J/kg.K. The specific heat of the vaporized natural gas is Cp,v = 2210 J/kg.K while the gas has a latent heat of vaporization of hfg = 575 kJ/kg. Seawater Thi = 20°C LNG T-155°C Seawater = 10°C The Vaporized gas to pipeline To=8°C Section C Vaporized gas -Section B Liquid to vapor phase change Vaporizer Section A Liquid gas (LNG) The LNG is heated with seawater flowing through the tubes, also introduced at the bottom of the vaporizer, that is available at Th,i = 20°C with a specific heat of Cp,sw= 3985 J/kg.K. If the gas is to leave the vaporizer at To = 8°C and the seawater is to exit the device at Tho = 10°C, determine the required vaporizer heat transfer area. Hint: Divide the vaporizer into three sections, as shown in the schematic, with UA = 150 W/m².K, UB=260 W/m².K, and Uc = 40 W/m².K.
