Title (EN) SYSTEM AND METHOD FOR NATURAL GAS LIQUEFACTION
(FR) SYSTÈME ET PROCÉDÉ DE LIQUÉFACTION DU GAZ NATUREL
Abstract:
(EN) A system for natural gas liquefaction includes a natural gas source for providing a flow of natural gas and a moisture removal system located downstream of the natural gas source. The system includes a first heat exchanger located downstream of the moisture removal system for exchanging heat between the natural gas flow path and a first refrigerant flow path of a refrigerant cycle subsystem. The system includes one first throttle valve located downstream of heat exchanger for expanding the flow of natural gas and causing reduction in pressure and temperature of the flow of natural gas. The system includes a filter subassembly for separating solid particles present in the flow of natural gas. The system includes a second heat exchanger located downstream of the filter subassembly and is configured to transfer heat from a natural gas vapor flow path to a second refrigerant flow path of the refrigeration cycle subsystem.
(FR) L'objet de l'invention porte sur un système de liquéfaction du gaz naturel qui comprend une source de gaz naturel pour fournir un flux de gaz naturel et un système déshumidificateur situé en aval de la source de gaz naturel. Le système comprend un premier échangeur de chaleur situé en aval du système déshumidificateur pour échanger de la chaleur entre le trajet de circulation du gaz naturel et un premier trajet de circulation de fluide frigorigène d'un sous-système à cycle de réfrigération. Le système comprend un premier papillon des gaz situé en aval de l'échangeur de chaleur pour dilater le flux de gaz naturel et pour réduire la pression et la température du flux de gaz naturel. Le système comprend un sous-ensemble filtrant pour séparer les particules solides présentes dans le flux de gaz naturel. Le système comprend un second échangeur de chaleur situé en aval du sous-ensemble filtrant et est configuré pour transférer de la chaleur à partir du trajet de circulation de vapeur de gaz naturel jusqu'à un second trajet de fluide frigorigène du sous-système à cycle de réfrigération.
