APPARATUS FOR THE LIQUEFACTION OF NATURAL GAS AND METHODS RELATING TO SAME
An apparatus and method for producing liquefied natural gas. A liquefaction plant may be coupled to a source of unpurified natural gas, such as a natural gas pipeline at a pressure letdown station. A portion of the gas is drawn off and split into a process stream (154) and a cooling stream (152). Th...

| description | An apparatus and method for producing liquefied natural gas. A liquefaction plant may be coupled to a source of unpurified natural gas, such as a natural gas pipeline at a pressure letdown station. A portion of the gas is drawn off and split into a process stream (154) and a cooling stream (152). The cooling stream (152) passes through a turbo expander (156) creating work output. A compressor (158) is driven by the work output and compresses the process stream. The compressed process stream is cooled, such as by the expanded cooling stream. The cooled, compressed process stream is divided into first and second portions with the first portion being expanded to liquefy the natural gas. A gas-Iiquid separator separates the vapor from the liquid natural gas. The second portion of the cooled, compressed process stream is also expanded and used to cool the compressed process stream. Additional features and techniques may be integrated with the liquefaction process including a water clean-up cycle and a carbon dioxide (CO2) clean-up cycle.
L'invention concerne un appareil et un procédé de production de gaz naturel liquéfié. Une installation de liquéfaction peut être couplée à une source de gaz naturel non purifié, telle qu'un pipeline de gaz naturel au niveau d'une station de réduction de pression. Une partie du gaz est retirée et répartie en un flux de traitement (154) et en un flux de refroidissement (152). Celui-ci (152) passe à travers un turbo-extenseur (156) créant une production. Un compresseur (158) est entraîné par la production et comprime le flux de traitement. Le flux de traitement comprimé est refroidi par expansion du flux de refroidissement. Le flux de traitement refroidi et comprimé est réparti en des première et seconde parties, la première partie étant expansée aux fins de liquéfaction du gaz naturel. Un séparateur gaz-liquide sépare la vapeur du gaz naturel liquide. La seconde partie du flux de traitement refroidi et comprimé est également expansée et elle est utilisée pour refroidir le flux de traitement comprimé. |
