Abstract
The quality stock-taking management of liquefied natural gas(LNG)receiving stations is a critical step in ensuring the accuracy of inventory management and the fairness in trade settlements.This study investigates the entire process of LNG receiving stations,including the process flow,measurement stages,metering equipment,and calculation methods,to establish a comprehensive quality stock-taking calculation model.Utilizing the developed quality stock-taking calculation model,the inventory calculations at the receiving station indicate that the daily gains and losses fluctuations range from-1 973.910 to 2 375.959 tons,with days of inventory losses accounting for 73.36%.During the vessel unloading process,the daily inventory fluctuations range from-1 692.935 to 114.346 tons,with inventory gains days accounting for 97.74%.The analysis of the quality stock-taking calculation results identifies the primary factors contributing to the fluctuations in inventory gains and losses,and targeted solutions are proposed to mitigate these fluctuations.Monitoring LNG receiving stations gains and losses fluctuations through quality stock-taking enables timely detection of operational management issues,providing a sound basis for inventory management in domestic LNG receiving stations and enhancing their economic efficiency.关键词
