Title (EN) PROCESS, PLANT AND OVERALL SYSTEM FOR HANDLING AND TREATING A HYDROCARBON GAS FROM A PETROLEUM DEPOSIT
(FR) PROCEDE, INSTALLATION ET SYSTEME GLOBAL DE TRAITEMENT D'UN GAZ D'HYDROCARBURES PROVENANT D'UN GISEMENT DE PETROLE
Abstract: front page image
(EN)A method of liquefaction/conditioning of a compressed gas/condensate flow extracted from a petroleum deposit, for transport in liquefied form with a transport vessel, especially for such processing of a compressed gas/condensate flow which has been separated from a crude oil extracted from an offshore oil field. The gas/condensate flow is depressurized and cooled in several steps for producing a stabilized liquefied natural gas (LNG) and a stabilized liquefied petroleum gas (LPG), for transport thereof in separate tanks. Disclosed is also a gas expansion plant for execution of the method, and a system for handling and processing of a natural gas from an offshore petroleum field, comprising a production ship to which there is supplied a well stream from an underground source, a field plant installed on the production ship, for processing of the well stream received on the production ship, a vessel for transport of liquefied gas fractions, a high-pressure pipeline arranged for transfer of compressed gas from the field plant to the vessel, and a gas expansion plant according to the invention installed on the transport vessel.
(FR)L'invention concerne un procédé de liquéfaction/conditionnement d'un flux de gaz/condensat comprimé extrait d'un gisement de pétrole et destiné à être transporté, sous forme liquéfiée, par un navire, notamment en vue de traiter un flux de gaz/condensat qui a été séparé du pétrole brut extrait d'un champ pétrolifère exploité en mer. Ce flux de gaz/condensat est dépressurisé et refroidi en plusieurs étapes afin de produire un gaz natural liquéfié stabilisé (GNL) et un gaz de pétrole liquéfié stabilisé (GPL) dont le transport est ensuite effectué dans des cuves séparées. L'invention concerne également une station d'expansion des gaz permettant d'exécuter le procédé, et un système de traitement de gaz natural provenant d'un champ pétrolifère exploité en mer, ce système comprenant un navire de production sur lequel est amené un flux de forage provenant d'une source souterraine, une station montée sur le navire de production et destinée à traiter le flux de forage amené sur le navire de production, un navire pour le transport de fractions de gaz liquéfié provenant de la station montée sur le navire de production, et une station d'expansion des gaz montée sur le navire de transport.
