液化石油气计量方法

鉴于目前国内没有统一的液化石油气数量的计算标准，又缺乏计算的基础数据，为此引用了国外有关标准中的基础数据，提供了液化石油气计量的参数和计算公式。同其它油品的计量一样，液化石油气数量的计算必须把真空中的质量换算在大气中的质量，由于液化石油气是储存在压力容器中，呈气液平衡状态，所以它在储罐内的质量应是其液体质量和饱和蒸气质量的总和。着重介绍了根据油罐测量资料进行液化石油气质量的计算方法，分别算出液相和

LPG Metering Method

There is no unified LPG metering standard in China, and no basic data sufficient for calculation are available to solve the problem, basic data selected in some codes bublished abroad are introduced to provide parameters and equation for LPG metering. Similar to other oil product metering, it is necessary for the vacumm mass to be converted into atmospheric mass in order to perform the calculation of gas and liquid due to the fact that it is stored in pressurized vessels, for which reason, the mass of the product stored in the tank should be the total sum of liquid mass and that of the saturated gas.In this paper, introduced with emphesis is the method of calculating LPG mass in the light of the measured data about tanks. Calculated out seperately for the LPG both in liquid and gasious phases, the volume, density, standardized volume and the mass in the air. The total sum of liquid phase and that of gas is the mass of LPG. Practical calculation on LPG storage capacity is done based on LPG tanks.
