Title
(EN) COLD BOX DESIGN FOR CORE REPLACEMENT
(FR) CONCEPTION DE BOÎTE FROIDE POUR REMPLACEMENT DE CŒUR
Abstract
(EN)
A cold box particularly for use in a LNG cryogenic processes in which a plurality of cores of heat exchanger units are mounted within a housing. Headers are positioned in the housing with feed lines connecting the headers to manifolds on the cores. The cores and headers are arranged such that no header is positioned to block the removal of any core through the front and/or back of the housing. A method of making the cold box is also disclosed.
(FR)
La présente invention concerne une boîte froide particulièrement utile dans des procédés cryogéniques à base de gaz naturel liquéfié (GNL) dans lesquels une pluralité de cœurs d'unités d'échangeurs thermiques est montée au sein d'un boîtier. Les colonnes d'évent sont positionnées dans le boîtier avec des conduites d'alimentation raccordant les colonnes d'évent aux manifolds sur les cœurs. Les cœurs et les colonnes d'évent sont disposés de telle sorte qu'aucune colonne d'évent ne puisse bloquer l'extraction d'un cœur par l'avant et/ou l'arrière du boîtier. L'invention concerne également un procédé de fabrication de la boîte froide.
