气田抗硫高压分离器的流场稳态分析

Steady-State Analysis of Gas Flow Field in Anti-Sulfur High-Pressure Separator

摘要: 高压分离器是气田生产中的重要设备。它承受高压，属于压力容器。本文采用CATIA软件建立设备的完整三维模型。然后利用fluent软件，对分离器内部的流场进行了有限元分析计算。结果表明，结构内部的速度场和压力场都变化不大。分离器内部的伞型罩帽不会改变分离器内部的速度场和压力场。从分离器承压角度考虑，建议在天然气入口位置增加遮挡板。

Abstract: High-pressure separator is important equipment in the gas production. It withstands high pressure belonging to pressure vessel. In this paper, CATIA software was used to build a complete three-dimensional model of the device. Then we used the fluent software to analyze flow field inside the separator by finite element method. The results showed that the structure of the internal velocity and pressure fields have not changed much. Umbrella cap inside separator did not change the speed and pressure fields of the internal separator. Considering the separator pressure, a plate added at the gas inlet pipe was proposed.
