进口LNG计量方法及影响计量精度的因素和提高精度措施

Import LNG Measurement Methods and Accuracy Affecting Factors as well as Accuracy Improving Measures

本文旨在通过分析探讨影响LNG贸易交接依据-能量准确计算的几个重要因素,在LNG的贸易交接计量过程中,把控好这些重要因素,使贸易交接计量结果达到可控以及准确的目的,从而避免LNG进口企业可能的经济损失。作者通过在实际工作中的应用来阐述进口LNG计量的过程和方法,以及影响计量精度的具体因素,包含LNG卸载前后船舱计量、卸载过程中LNG取样、NG样品分析、不同标准运用、以及数据计算等步骤。以及探讨针对这些因素如何进行有效控制和需要特别关注的关键步骤,以推动LNG贸易交接计量精度的不断提高。

This paper aims to analyze and discuss several important factors that could affect the accurate calculation of transferred LNG energy. In the processof LNG trade measurement process, these important factors should be pay attention in order to make the LNG measurement results accurate and under the control, soas to avoid possible economic losses of LNG import enterprises. The author explains the imported LNG measurement process and method as well as the specificfactors affecting the measurement accuracy through the application in practical work, including steps of before and after LNG unloading, LNG sampling, sampleanalysis, different quoted standards, and data calculating. It also discusses how to effectively control these factors and the key steps that need to pay particularattention to, hopefully to promote the continuous improvement of measurement accuracy of LNG transfer trades.
