Title (EN) APPARATUS, SYSTEM AND METHOD FOR RELIQUEFACTION OF PREVIOUSLY REGASIFIED LNG
(FR) APPAREIL, SYSTÈME ET PROCÉDÉ DE RELIQUÉFACTION DE GNL PRÉALABLEMENT REGAZÉIFIÉ
Abstract:
(EN) An apparatus, system and method for reliquefaction of previously regasified LNG are described. A natural gas reliquefaction method includes regasifying LNG onboard a FSRU to form high pressure regasified LNG (HP RLNG), delivering the HP RLNG to a natural gas pipeline that commingles with a natural gas grid, flowing the HP RLNG through a lateral, wherein the lateral diverts HP RLNG from the natural gas pipeline to an expander prior to commingling with the natural gas grid, expanding the natural gas with the expander to obtain low pressure regasified LNG (LP RLNG), liquefying the LP RLNG in a cold box of a nitrogen expansion loop to produce low pressure LNG, and transmitting the LNG to a cryogenic cargo tank onboard an LNG tanker truck.
(FR) L'invention concerne un appareil, un système et un procédé de reliquéfaction de GNL préalablement regazéifié. Un procédé de reliquéfaction de gaz naturel selon l'invention consiste à regazéifier du GNL à bord d'une FSRU afin de former du GNL regazéifié à haute pression (RGNL HP), à distribuer le RGNL HP à un pipeline de gaz naturel qui se mélange avec un réseau de gaz naturel, à faire circuler le RGNL HP par un pipeline latéral, le pipeline latéral déviant le RGNL HP du pipeline de gaz naturel vers un détendeur avant de se mélanger avec le réseau de gaz naturel, à provoquer l'expansion du gaz naturel au moyen du détendeur afin d'obtenir du GNL regazéifié à basse pression (RGNL LP), à liquéfier le RGNL LP dans une boîte froide d'une boucle d'expansion d'azote afin de produire du GNL basse pression, et à transmettre le GNL à un réservoir de cargaison cryogénique à bord d'un camion-citerne de GNL.
