Method for producing pressurized liquefied natural gas, and production system used in same


A method for producing pressurized liquefied natural gas and a production system therefor are provided. The method for producing pressurized liquefied natural gas includes: performing a dehydration process to remove water from natural gas supplied from a natural gas field, without a process of removing acid gas from the natural gas; and performing a liquefaction process to produce pressurized liquefied natural gas by liquefying the natural gas, which has undergone the dehydration process, at a pressure of 13 to 25 bar and a temperature of −120 to −95° c., without a process of fractionating natural gas liquid (ngl).

Integration of a liquefied natural gas liquefier with the production of liquefied natural gas


A method for integrating a liquefied natural gas liquefier system with production of liquefied natural gas from a methane-containing gas stream. The liquefied natural gas is produced by feeding a methane-containing gas stream through a heat exchanger to a distillation column and liquefying the natural gas while capturing the gaseous nitrogen.

Ship for transporting a liquefied natural gas storage container


An lng storage container carrier includes: one or more cargo holds provided on a hull such that upper portions thereof are opened; a plurality of first and second upper supports installed on the cargo holds in a width direction and a length direction to partition the upper portions of the cargo holds into a plurality of openings, wherein storage containers are vertically inserted into the openings and supported; and a lower support installed under the cargo holds and supporting the bottoms of the storage containers inserted into the openings. Accordingly, it is possible to efficiently and stably transport the storage containers storing lng or plng pressurized at a predetermined pressure.

Simplified lng process


A simplified method for production of a commercial supply liquefied natural gas (lng) supplied in a pressurized vessel includes taking a supply of natural gas including contaminants from a stranded well or from a pipe line and extracting from the supply gas water vapor and co2 in a fixed bed absorption system. In a first stage the supply gas is separated into first and second streams where the first stream contains all the cold energy available from the feed stream and sufficient of the contaminants are removed to meet a product specification for the composition of the lng supply.

High-strength steel material having outstanding ultra-low-temperature toughness and a production method therefor


The present invention provides steel containing manganese and nickel that is used as a structural material for a cryogenic storage container for liquefied natural gas (lng) or the like, and a manufacturing method thereof; and more particularly, to steel having good cryogenic temperature toughness and also high strength by adding low-cost mn instead of relatively expensive ni at an optimized ratio, refining a microstructure through controlled rolling and cooling, and precipitating retained austenite through tempering, and a manufacturing method of the steel. To achieve the object, the technical feature of the present invention is a method of manufacturing high-strength steel with cryogenic temperature toughness.

Methods for storing cryogenic fluids in storage vessels


A method for maintaining a subcooled bottom state or the natural convection current of a liquefied natural gas in a storage vessel by the use of an external heat exchanger. The liquefied natural gas is removed from the storage vessel and cooled in the external heat exchanger by a cryogenic fluid such as liquid nitrogen.
