    Abstract: A process for vaporizing liquefied gas is provided. Energy can be transferred within one or more first heat exchangers from a heat transfer medium at a first temperature to a liquefied gas. At least a portion of the liquefied gas can be vaporized within the one or more first heat exchangers to provide an at least partially vaporized liquid and a heat transfer medium at a second temperature. The heat transfer medium can be heated from the second temperature to a temperature at or near the first temperature with air within one or more second heat exchangers. The heat transfer medium from the one or more second heat exchangers can be directed to the one or more first heat exchangers.

    Abstract: A process for removing nitrogen from liquefied natural gas (LNG) using an enhanced surface, reflux heat exchanger is disclosed. A relatively warm high pressure LNG stream is directed countercurrently in heat exchange with a cool low pressure LNG stream to chill the high pressure stream and partially vaporize the low pressure LNG stream in the reflux heat exchanger. Vapor produced thereby strips the low pressure LNG stream of nitrogen. The cool low pressure LNG stream is produced by expansion of the chilled high pressure LNG stream. Vapor produced by the expansion is combined with the vapor produced in the exchanger and withdrawn overhead. Product LNG which is lean in nitrogen is withdrawn from the bottom of the exchanger.
