Scientific Novelty
A liquefied natural gas storage system using a gas ejector, where natural gas from a high-pressure supply pipeline is used as the working fluid, allows for increasing the pressure of boil-off gas at the system outlet and using the resulting gas mixture for the technological needs of the tank farm, while avoiding the use of a compressor unit for this purpose.
Advantages
The main efficiency factor is energy savings, specifically boil-off gas recovery, with a flow rate of 1.9 kg/s per discharge for a 300 m3 small-scale tank. Pressure is increased using an ejector approximately 2.8 m long and weighing about 30 kg, with an estimated cost of $50. These figures are 103 times lower in metal consumption and 172 times lower in cost compared to using a compressor for the same flow rate (3.1 tons, $8,600).
Commercial Implementation
Reconstructed, retrofitted, and newly designed LNG tank farms and tankers; implementation of import-substituting boil-off gas utilization technologies.
