Title (EN) METHOD FOR COOLING A PROCESS STREAM
(FR) PROCÉDÉ PERMETTANT DE REFROIDIR UN FLUX DE TRAITEMENT
Abstract: front page image
(EN)The invention provides a method of cooling a process stream (52) associated with the treatment of natural gas, the method comprising the steps of : (a) providing a liquid coolant stream (38) in an open recirculating cooling circuit and providing a process stream; (b) evaporating (30) a portion of the liquid coolant stream by contacting the liquid coolant stream with a gaseous stream (44) to provide a cooled liquid coolant stream and a gaseous stream comprising coolant (32); and (c) heat exchanging (40) the cooled liquid coolant stream against the process stream to provide a cooled process stream (51).
(FR)L'invention concerne un procédé de refroidissement d'un flux de traitement (52) associé au traitement du gaz naturel. Ce procédé comprend les étapes consistant à : (a) fournir un flux de réfrigérant liquide (38) dans un circuit ouvert de refroidissement par recirculation et fournir un flux de traitement ; (b) évaporer (30) une partie du flux de réfrigérant liquide en le mettant en contact avec un flux gazeux (44) afin d'obtenir un flux de réfrigérant liquide refroidi et un flux gazeux comprenant du réfrigérant (32) ; et (c) réaliser un échange thermique (40) entre le flux de réfrigérant liquide refroidi et le flux de traitement afin d'obtenir un flux de traitement refroidi (51).
