Liquefied hydrocarbon gas carried by a tanker (78) is transferred to an import terminal (10) where the liquefied gas is heated to vaporize it and to heat the cold gas to at least -30°C but preferably about 0°C, with the warmed gas transferred to a gas receiving facility (20, 83). Vaporizing and heating is accomplished by using a large number (more than 10) of vertically mounted air vaporizers (84) of a known type, which use environmental air that flows down the exterior of the finned tubes in which the liquefied or cold gas flows. In the present invention a large number of individual vaporizers are positioned in close proximity to each other, i.e. within a distance that is smaller than half the vertical height of the vaporizer tubes. Their close proximity allows many units to be installed on a small plot space, and also affects their thermal performance. |
