Baranov A.Yu., Valentinova K.A., Ivanov L.V. Modeling of liquefied natural gas evaporation in mobile reservoirs. Scientific and Technical Journal of Information Technologies, Mechanics and Optics, 2020, vol. 20, no. 4, pp. 595–602 (in Russian). doi: 10.17586/2226-1494-2020-20-4-595-602

The paper presents the analysis of isothermal storage of liquefied natural gas within the conditions of river navigation. The effect of constructive and technological solutions on the safety and profitability of liquefied natural gas application as an alternative to petroleum products is studied. The technique principle consists in a cryogenic storage modeling based on the energy equation of the vapor and liquid fractions and comparative analysis of several options for transportation of liquefied natural gas by river transport. In consequence of the study results, data were obtained on the relationship between the insulation thickness and the degree of tank filling having an effect on transport characteristics. It was revealed that transportation of liquefied natural gas in gas-insulated storage facilities is technically possible and satisfactory by combining the optimal specific volume of cryogenic liquid in the tank and sufficient thickness of thermal insulation. The results obtained can be used in the development of autonomous floating containers with a large insulation thickness, which will be towed along rivers without the use of carrier vessels.
