ISO 21903:2020 冷冻碳氢化合物液体 动态测量 液化天然气（LNG）和其他冷烃流体用流量计的校准和安装要求和指南

This document specifies the metrological and technical requirements for flowmeters intended to be used for the dynamic measurement of liquefied natural gas (LNG) and other refrigerated hydrocarbon fluids. For LNG static volume measurement used in custody transfer, see ISO 10976. This document sets the best practice for the proper selection and installation of flowmeters in cryogenic applications and identifies the specific issues that can affect the performance of the flowmeter in use. Moreover, it offers a calibration guideline for laboratory and on-site conditions (mass or volume) by either using LNG or other reference fluids. The choice of calibration fluid will depend on the capabilities of the available flow calibration facilities and the ability to achieve the required overall measurement uncertainty demanded by the intended application. This document is applicable, but is not limited, to the use of Coriolis and ultrasonic flowmeters for dynamic measurements of LNG. In principle, LNG and other refrigerated liquid hydrocarbons are considered in this document. Recommendations in this document are based on the available test results with LNG. These results are probably applicable to other cryogenic fluids.

1   Scope This document describes and discusses the characteristics of turbine flowmeters. Attention is given to the factors to be considered in the application of turbine meters to liquid metering. These include the properties and nature of the liquid to be metered, the correct installation and operation of the meter, environmental effects, and the wide choice of secondary and ancillary equipment. Aspects of meter proving and maintenance are also discussed. This document is applicable to the metering of any appropriate liquid. Guidance is given on the use of turbine meters in the metering of two-component liquid mixtures such as water and oil. It is not applicable to two-phase flow when gases or solids are present under metering conditions (i.e. two-phase flow). It can be applied to the many and varied liquids encountered in industry for liquid metering and is not restricted to hydrocarbons. Guidance on the performance expected for fiscal/custody transfer applications for hydrocarbons is outlined. This document is not applicable to cryogenic liquids, such as liquefied natural gas (LNG) and refrigerated petroleum gas. It does not cover potable water applications.

This document specifies minimum requirements to quantify the boil-off gas (BOG) consumed on liquefied natural gas (LNG) carriers for their own functions, notably for power generation, during cargo transfer operations. BOG in this document refers to the low molecular gas returned from shore tanks to ships’ tanks and the gas produced in ships’ cargo tanks. This document provides requirements for the metering of BOG and the subsequent calorific value calculations which can be taken into account when the energy transferred during cargo transfer is determined. This document also introduces performance requirements and calibration of the elements included in the BOG measurement system. A flowmeter of any type may be used to measure BOG as long as it meets the performance requirements specified in this document. This document, with some modification, can also be applied to the measurement of BOG consumed by LNG carriers at sea.
