Abstract
A method for vaporizing a liquid stream includes cycling a heat transfer fluid in a closed circuit; feeding the heat transfer fluid to a first heat transfer zone; feeding a liquid stream to be vaporized to the first heat transfer zone; providing heat from the heat transfer fluid to the liquid stream in the first heat transfer zone thereby vaporizing the liquid stream and at least partially condensing the heat transfer fluid; removing the vaporized liquid stream and the at least partially condensed heat transfer fluid and passing the latter to a second heat transfer zone; providing heat from ambient air to the at least partially condensed heat transfer fluid thereby vaporizing the heat transfer fluid; recycling the vaporized heat transfer fluid to the first heat transfer zone using gravitational force exerted on the heat transfer fluid being cycled in the closed circuit.
