新型超音速旋流分离器流场分析与性能评估
Flow field analysis and performance evaluation on new supersonic swirling separator
摘要
Abstract
To solve the problem of the high-pressure natural gas containing water vapor in real oil production,a type of front-placed supersonic dehydration device was designed according to gas field condition and gas well drilling technology parameters. Both numerical simulation and performance study were carried out for the new device. Based on the physical dimension,a three-dimensional CFD model was established,and the RNGk-ε turbulence model was selected to simulate the internal flow field of the supersonic separator. The separation parameters such as pressure,temperature,velocity and Mach number along the axis inside the supersonic separator were investigated. The flow characteristics along the radial direction in different sections were also discussed. In addition,the performance of the device was also carried out to validate the numerical model. The results showed that the Mach number could reach 1.51 at a low temperature of 140K and the tangential velocity was 160m/s,which can realize fully water vapor condensation and separation. When pressure loss ratio was 70%,the dehydration of dry gas could be up to 32℃. At the same time,the new device accommodating to variable pressures and temperatures completely meets the requirements of actual production.关键词
