The originator of SCV’s for vaporization of LNG and the pioneer of many cryogenic fluid vaporization applications, T-Thermal (later acquired by Selas Fluid Processing - now Linde Engineering North America) designed and supplied the very first submerged combustion system in 1965. Today, we have over 300 LNG vaporizers installed world wide for both peak shaving and base load applications.
Our vaporizers focus primarily on the heating and/or vaporization of cryogenic and low temperature fluids. Though we have experience with oxygen, nitrogen, ethylene, ammonia, and propane, our vaporizer systems are most frequently applied for vaporization of LNG in base load and peak shaving regasification facilities.
LNG for Base Load and Peak Shaving Service
Liquefied natural gas, commonly called LNG, is easily transported overseas to receiving terminals and stored in insulated tanks before use. The liquid is then heated and converted to ordinary natural gas prior to direct transport to market. Selas Fluid's vaporizer systems are used to vaporize LNG before transmission into natural gas pipelines to meet utility needs. For base load service, operation of the vaporizer is the primary means of LNG vaporization on a continuous basis. Typically, vaporizers for base load service utilize a large single burner to minimize emissions and have vaporization capacities up to 200 t/h. Our vaporizers can also be installed and operated utilizing an available warm water supply either independently or to supplement the burner firing rate.
The submerged combustion vaporizer (SCV) is an indirect fired heat exchanger with the burner and process tube coil contained within a single vessel. The design is based on the submerged exhaust principle whereby the burner combustion products are discharged into a water bath, which is used as the heat transfer media for vaporizing the LNG in the tube coil.
