Selection of technological solutions to reduce LNG loss in supply pipelines to LNG terminal
摘要
reduction of technological losses of natural gas during production, transportation and storage is of major energy and environmental importance. Losses of natural gas are the target for active criticism by “green energy” representatives. It is necessary to develop and popularize the new technological solutions aimed at reducing the indirect impact on the environment associated with the production and use of liquefied natural gas, to demonstrate the readiness of specialists of this energy sector to take into account modern social preferences. The article presents the numerical analysis of the energy efficiency for one of the stages of large-scale LNG production, namely, the LNG delivery from a storage tank to a LNG carrier vessel via a cryogenic pipeline. The mathematical model of the thermal enclosure of the pipeline has been considered, and the production cryoproduct losses due to thermal inertia of pipeline materials have been estimated. The performance of the schemes recommended for utilization of LNG vapors has been evaluated.
