Definitions

  • aspects of the invention relate to liquefied natural gas (LNG). More specifically, aspects of the invention relate to stripping of hydrocarbons from LNG.
  • LNG liquefied natural gas
  • LNG is becoming a significant source of energy throughout many parts of the world.
  • LNG is delivered to a LNG terminal as a pipeline quality gas.
  • LNG is sometimes delivered to the LNG terminal as non pipeline quality gas and is processed after re-gasification by a gas processing plant that removes substantially all of the hydrocarbons heavier than methane (such as ethane, propane, etc.) so that the remaining gas meets the pipeline quality standards.
  • gas processing plants are common in the gas producing regions of the country.
  • a method of providing LNG to a customer comprising: providing a volume of LNG 1 stripping hydrocarbons other than methane from the LNG at either a LNG terminal or aboard a cryogenic articulated barge, and offloading the stripped LNG to an end use customer.
  • the method may be accomplished such that the stripping of the hydrocarbons is performed in an approximately temperature constant environment.
  • the method is accomplished such that the stripping of the hydrocarbons comprises re-gasifying the LNG, removing the hydrocarbons other than methane, and re-liquefying the re gasified natural gas.
  • Figure 1 is a gas quality stripping method in conformance with an embodiment of the present invention.
  • a process for removing heavy hydrocarbons from LNG at a transit terminal is presented.
  • a fractionation technique is used to minimize a temperature gain of methane in a re-gasification process.
  • methane remains in a dense phase and is substantially cool while heavier hydrocarbons are removed.
  • heavy hydrocarbons are removed from the lid provide natural gas on board a cryogenic articulated barge. After removal of the heavy hydrocarbons, the remaining LNG will meet pipeline quality standards and therefore will be usable by an end user.
  • non pipeline quality gas may be delivered by a cryogenic articulated barge directly to a consumer site.
  • the consumer site may be modified such that the individual combustion process of the facility is modified to accept higher the range gas to be burned.
  • a method of stripping heavy hydrocarbons from LNG is presented.
  • LNG is provided to a transit terminal 110.
  • natural gas components other than methane are stripped from the LNG 120 at the LNG transit terminal.
  • the remaining LNG is transported to an end use customer 130.
  • the removal of the LNG may be accomplished at a processing facility, onboard a cryogenic articulated vessel or at the end user site as necessary.
  • nitrogen may be injected into nonpipeline quality gas in order to lower the non-pipeline gases thermal output at the customer site. This dilution may be performed to bring the gas into conformance with expected heating values needed at the end it use customer point.

Abstract

L'invention porte sur un procédé de fourniture de gaz naturel liquéfié (LNG) à un client. Ce procédé comprend les étapes consistant à fournir un volume de LNG, dégazoliner le LNG pour éliminer les hydrocarbures autres que le méthane soit à un terminal de LNG soit à bord d'une barge articulée cryogénique, et décharger le LNG dégazoliné pour l'adresser à un client final.
