Double Inlet Cyclone Separators for Natural Gas Dehydration

Abstract

The fluid flow in the double cyclone separator is numerical simulated, using the Navier-Stokes equations with the Reynolds stress model (RSM). The basic parameters of gas flow are obtained as functions of radius such as the tangential velocity, the axial velocity and the static pressure. The numerical results show that in the cyclones water liquids are centrifuged onto the walls and removed from the natural gas due to the strong centrifugal field, while the natural gas stays in the central region and moves out from the up-outlet. The water can be well removed from the natural gas.
