【摘要】：为合理确定海底湿气输送管道终端段塞流捕集器的容积尺寸,将海底管道和段塞流捕集器视为一个整体,采用稳态模拟软件Pipeflo对湿气管道进行模拟计算。首先,根据稳态模拟结果确定段塞流捕集器的液体排量;其次,通过确定清管工况段塞容积,初步得出段塞流捕集器的储存段容积和水的缓冲容积;最后,根据不同输量下管内滞液量计算Ramp-up工况段塞容积,校核段塞流捕集器的排放能力和容积,从而确定管道终端段塞流捕集器的容积。结果表明:根据不同输量下稳态计算结果确定清管和Ramp-up工况下产生的最大段塞量,其计算结果与OLGA软件模拟结果相差较小,因此,通过稳态模拟确定段塞流捕集器尺寸是合理可行的,且该方法简单便捷,为项目早期研究提供了技术支撑。
[Abstract]:In order to reasonably determine the volume size of the terminal slug trap of the submarine wet gas pipeline, the submarine pipeline and the slug trap are regarded as a whole, and the steady state simulation software Pipeflo is used to simulate the wet gas pipeline. Firstly, according to the steady state simulation results, the liquid discharge of slug trap is determined. Secondly, by determining the slug volume in pigging condition, the storage section volume and water buffer volume of slug trap are preliminarily obtained. The slug volume of Ramp-up working condition is calculated according to the amount of stagnant fluid in the pipe under different transports, and the discharge capacity and volume of slug trap are checked, so as to determine the volume of slug trap at the end of pipeline. The results show that according to the steady-state calculation results of different quantities of transport, the maximum slug amount produced under the conditions of pipe-clearing and Ramp-up is determined, and the difference between the calculated results and the simulation results of OLGA software is relatively small. It is reasonable and feasible to determine the size of slug trap by steady state simulation, and the method is simple and convenient, which provides technical support for the early research of the project.
