We deliver submerged combustion vaporisers (SCVs) for heating and/or vaporising cryogenic and low-temperature fluids. The technology is primarily used for vaporising LNG in base-load and peak-shaving regasification facilities. However, we also have experience with liquid oxygen (LOX), liquid nitrogen (LIN), ethylene, ammonia and propane.
Our SCVs are indirectly fired heat exchangers contained within a single vessel. They are based on the submerged exhaust principle, whereby the burner combustion products are discharged into a water bath, which is then used as the heat transfer medium for vaporising LNG in the tube coil.
Typically, our vaporisers utilise a large single burner to minimise emissions and can vaporise up to 200 t/h of LNG. In base-load facilities, vaporisers are the main method of vaporising LNG and are used continuously. However, SCVs can also be installed and operated independently or as a supplement to the burner firing rate with their own supply of warm water.
We have delivered over 300 units worldwide since the first installation in 1965. Backed by a wealth of experience in this technology, our SCVs ensure:
High thermal efficiency of over 99 percent on average
Uniform temperatures (no build-up of ice on tubes)
Rapid response thanks to fast start-up and shut down without process disruptions
Highest safety levels (no flame impingement on LNG coils)
Fuel savings thanks to high thermal efficiency and easy integration with supplemental heat sources
NOX emissions of < 40 ppm
