The numerical results show that the compressibility factor and specific heat ratio for ideal gas law diverge remarkably from real gas models at a high inlet pressure. Simultaneously, the deviation of mass flow calculated by the ideal and real gas models reaches over 10 %. The difference increases with the lower of the inlet temperature regardless of the inlet pressure. A higher back pressure results in an earlier location of the shock wave. The pressure ratio of 0.72 is the first threshold to get the separator work normally. The second threshold is 0.95, in which case the whole flow is subsonic and cannot reach the choked state. The shock position moves upstream with the real gas model compared to the ideal gas law in the cyclonic separation section. 6 Oil and Gas Science and Technology 70 ARTICULO Wen, Chuang 55146 Cao, Xuewen 55147 Yang, Yan 55113 Feng, Yuqing 55148 189444 189444 0 0 0 0 257263 BAAB BAAB 2026-03-06 200061680 0 200061680 2026-03-06 00:19:38 2026-03-06 ARTICULO
