NUMERICAL SIMULATION ON NATURAL GAS SEPARATION THROUGH SUPERSONIC NOZZLES
A new supersonic nozzle was designed for natural gas separation, at the entrance of which several swirling vanes were installed. The swirling separation of natural gas through the supersonic nozzle is numerically simulated with the RNG k-ε model. Axial distribution of the main parameters of gas flow is investigated, and the effects of the nozzle geometry on the swirling separation are analyzed. The numerical results show that water and heavy hydrocarbons can be condensed and separated from natural gas under the combined effects of the low temperature (-75℃) and centrifugal field (448 000 g. g is the acceleration of gravity). The influence of throat profile on the swirling separation performance is very small.
