LNG Submerged Combustion Vaporizers

Cryonorm developed a range of submerged combustion vaporizers (SCV) for regasification of medium – and large quantities of LNG.

he LNG is warmed by flowing through tube bundles that are submerged in a waterbath which is heated by flue gases coming from natural gas fired burners. The submerged combustion burner emits hot exhaust gas that directly heats the waterbath by bubbling through the water to an exhaust stack. The flue gas will be cooled below the dew point, the water from the combustion condenses out giving up its latent heat to the water bath. Since both the sensible and the latent heat contents of these flue gases are recovered in the water, the overall thermal efficiency is very high.

3D model and picture below shows two fully shop manufactured SCV units ion, each designed for vaporizing duty of 25.000 Nm³/hr LNG.Supply includes insulated stainless steel tank in order to minimize site works and installation time.
