Liquid Gas Evaporator
Directly fired evaporator systems were developed, patented and built for the first time in 1965 by the SELAS-LINDE subsidiary T-Thermal. Since then, the Sub-X ® evaporator system has been continuously refined. The technology is used worldwide in LNG terminals for both basic load and peak load supply.
The Sub-X ® evaporator system consists of a water container in which a heat exchanger bundle is incorporated. The Sub-X ® burner produces a flue gas which is brought into contact with the water bath and which heats this and thus also the ultra-low temperature medium which is to be evaporated. A patented flue gas distribution system means that very high heat transfer rates can be achieved, so that an even energy supply to the medium is possible even at partial loads.
| since 1964 |

|
Up to 40 MW |
| Emissions: |
|
Complies with current TA Luft regulations |
| Efficiency: |

Limit values > 100% possible (in relation to lower calorific value) |
| Delivery time: |
|
approx. 10 months |
| Heating and evaporation of the following ultra-low temperature feed products: |
|
LNG
LPG
liquid nitrogen
oxygen
ammonia
ethylene |
| Firing: |
|
Sub-X burner system for oil and/or gas and lean gas |
| Operating safety: |
|
The process tubes are in a water bath, the maximum wall temperatures are less than 55°C. It is impossible for the flame to come into direct contact with the heat exchanger tubes. |
| Extremely fast load changes possible |
|
|
| Very good heat transfer, even under partial load |
|
thanks to a patented flue gas distribution system and high turbulences. |
