摘要

计算输、储油设备在不同技术状况下，以及不同作业过程中的油品蒸发损耗量，其目的是为评价各种降耗技术费措施的经济效果，为实施这些技术措施的技术经济分析和论证提供依据。动液面损耗是油品收发作业中由于液面高度变化而造成的油品损耗。容器气体空间原有的空气逐渐变为趋于均匀分布的烃蒸气和空气的混合气体，当外界条件变化引起混合气体状态参数改变时，混合气体从大容器排入大气，就造成了油品的蒸发损耗。为了保障油田安全生产运行,减少油品损失,对固定顶储油罐的蒸发损耗量进行计算具有重要意义。本文总结了固定顶储罐的大呼吸损耗及通风损耗的产生机理,以瓦廖夫斯基-契尔尼金公式为基础,给出了不同类型的蒸发损耗计算方法。

Abstract

Calculation of transmission, storage equipment in different technical conditions,and different operation in the process of evaporation loss of oil quantity, its purpose is to evaluate various saving technology fee measures of economic effect, provides the basis for

the implementation of these technical measures oftechnical and economic analysis and demonstration. The dynamic liquid level of oil loss loss is caused due to the height of the liquid level changes of oiltransceivers operating in. Air gas containers of the original

space gradually uniform distribution as tends to hydrocarbon vapor and air mixed gas, when the external conditions change causes a change in the state parameters of mixed gas, mixed gas from the container into the atmosphere, causing the evaporation loss of oil. In order to run safety production guarantee oil and reduce oil losscalculation has important significance on evaporation loss amount fixed top storage tank. This paper summarizes

the mechanism of fixed roof storage tankbig breathing loss and windage loss, in

watts Liao Fusi base - Qiernijin formula as the basis, this paper presents a method to calculate the evaporation loss of different types.
