1. An apparatus for heating a liquefied stream, comprising a closed circuit for cycling a heat transfer fluid, the closed circuit comprising a first heat transfer zone, a second heat transfer zone, and a downcomer, all arranged in an ambient, wherein the first heat transfer zone comprises a first box in the form of a shell that contains the heat transfer fluid, which first box stretches longitudinally along a main axis, wherein a first heat transfer surface is arranged inside the first box, across which first heat transfer surface a first indirect heat exchanging contact is established between a liquefied stream that is to be heated and the heat transfer fluid, wherein the second heat transfer zone is located gravitationally lower than the first heat transfer zone and where 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, and wherein the downcomer fluidly connects the first heat transfer zone with the second heat transfer zone, wherein the downcomer comprises a first transverse portion and a first downward portion that are fluidly connected to each other via a connecting elbow portion, wherein the connecting elbow portion when viewed in a vertical projection on a horizontal plane is located external to the first box compared to the main axis. |
