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.
Claims20
1) A process for vaporizing liquefied gas, comprising:
- transferring energy within one or more first heat exchangers from a heat transfer medium at a first temperature to a liquefied gas, wherein at least one of the one or more first heat exchangers is a gas fired vaporizer;
- vaporizing at least a portion of the liquefied gas 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;
- heating the heat transfer medium from the second temperature to a temperature at or near the first temperature with air within one or more second heat exchangers;
- and
- directing the heat transfer medium from the one or more second heat exchangers to the one or more first heat exchangers.
7) A process for vaporizing liquefied gas, comprising:
- transferring energy within one or more first heat exchangers from a heat transfer medium at a first temperature to a liquefied gas, wherein at least one of the one or more first heat exchangers comprises:
- a combustion chamber, burner, and tube, the tube at least partially submerged within the heat transfer medium;
- vaporizing at least a portion of the liquefied gas 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;
- and
- heating the heat transfer medium from the second temperature to a temperature at or near the first temperature with air within one or more second heat exchangers;
- and
- directing the heat transfer medium from the one or more second heat exchangers to the one or more first heat exchangers.
19) A process for vaporizing liquefied gas, comprising:
- transferring energy within one or more first heat exchangers from a heat transfer medium to a liquefied gas, wherein at least one of the one or more first heat exchangers comprises:
- a combustion chamber, burner, and tube, the tube at least partially submerged within the heat transfer medium;
- vaporizing at least a portion of the liquefied gas in the one or more first heat exchangers to provide an at least partially vaporized liquid and a heat transfer medium at a second temperature;
- directing the heat transfer medium to one or more first sumps;
- heating the heat transfer medium from the second temperature to a temperature at or near the first temperature with air within at least one second heat exchanger selected from an air heater or quench column;
- directing the heat transfer medium from the at least one second heat exchanger to one or more second sumps;
- and
- directing the heat transfer medium from the one or more second sumps to the one or more first heat exchangers.
