Title:
METHOD AND APPARATUS FOR HEATING A LIQUEFIED STREAM
Document Type and Number:
WIPO Patent Application WO/2013/186275
Kind Code:
A3
Abstract:
In a closed circuit a heat transfer fluid is cycled from a first heat transfer zone to a second heat transfer zone via a downcomer, all arranged in an ambient. The first heat transfer zone, housed inside a first box, comprises a first heat transfer surface across which a liquefied stream that is to be heated is brought in a first indirect heat exchanging contact with the heat transfer fluid. The heat transfer fluid is allowed to condense, and a part of the condensed portion of the heat transfer fluid is allowed to accumulate within the first box thereby forming a liquid layer of the heat transfer fluid in the liquid phase within the first box. Liquid is drawn from the liquid layer and passed through the downcomer to the second heat transfer zone. The second heat transfer zone comprises a second heat transfer surface across which the heat transfer fluid is brought in a second indirect heat exchanging contact with the ambient.
