Abstract
A method for liquefying a hydrocarbon stream using a heat exchanger having a plurality of plates parallel to each other and to a longitudinal direction that is substantially vertical, the exchanger having a length measured in the longitudinal direction, the plates being stacked with spacing so as to define between them at least one first series of passages for the flow of at least part of a two-phase cooling stream vaporizing by exchanging heat with at least the hydrocarbon stream.
