Thermodynamic analysis and modeling of the filling process of a gas tanker by shipping LNG from a large-capacity storage facility with an upgraded submersible cryogenic pump

Abstract

Objective. To set the parameters of the liquefied natural gas shipment system for various options for filling a gas tanker from large-capacity storage facilities during its bunkering.Method. Mathematical and numerical modeling of the liquefied natural gas shipment process for various tank-emptying modes during the shipment of liquefied natural gas to a largecapacity gas carrier by a submersible cryogenic pump.Result. The analysis of the modes of shipment of liquefied natural gas from large-capacity storage facilities has been carried out in order to ensure filling of a gas tanker within the permissible freight period with an upgraded design of a submersible pump of liquefied natural gas. Analytical dependencies have been obtained to describe the process of shipping liquefied natural gas for various operating options of the shipping system.Conclusion. The optimal option for the operation of the liquefied natural gas shipment system for filling a gas tanker within the permissible bunkering time has been determined.
