摘要

本文是利用液化石油气货物的蒸汽从储罐中去除任何惰性气体的热力学分析（称为货舱充气操作）。为此，建立了一个热力学模型，该模型考虑了该过程的两个边界情况。第一种是使用液化石油气蒸汽对惰性气体进行“活塞推动”。第二种情况是将两种气体完全混合，并将混合物从储罐中排出到大气中，直到达到储罐中液化石油气货物的所需浓度或数量。通过计算，可以确定用于完成操作的气体量及其由于两种气体的完全混合而产生的损失。

Analysis of selected aspects of a tank gassing-up process on board liquefied petroleum gas carrier. Part I

The paper is a thermodynamics analysis of the removal of any inert gas from the tank using the vapors of any liqueﬁed petroleum gas cargo (called cargo tank gassing-up operation). For this purpose, a thermodynamic model was created which considers two boundary cases of this process. The ﬁrst is a ‘piston pushing’ of inert gas using liqueﬁed petroleum gas vapour. The second case is complete mixing of both gases and removal the mixture from the tank to the atmosphere until desired concentration or amount of liqueﬁed petroleum gas cargo in the tank is reached. Calculations make it possible to determine the amount of a gas used to complete the operation and its loss incurred as a result of total mixing of both gases.
