摘要：

According　to　the　characteristics　of　offshore　platforms,　this　paper　in　detail　presents　the　operating　principle　and　configuration　design　of　the　new　offshore　hydrate　separator.　This　device　can　be　used　to　separate　hydrates　and　liquids　form　natural　gas　without　using　chemicals,　and　there　are　some　benefits　including　energy　conservation,　environmental　protection,　compact　structure,　small　floor　space　and　high　separating　efficiency.　At　the　same　time,　basing　on　the　precise　multiphase　fluid　dynamics　theory　and　computational　fluid　dynamics　(CFD),　the　unsteady　gas-liquid　flows＇　key　parameters　that　influence　separation　performance　have　been　numerically　simulated.　Simulation　results　show　that　this　mathematical　model　and　numerical　method　are　correct,　and　can　forecast　and　reflect　variable　rule　of　gas-liquid　phase　volume　fractions　inside　the　new　offshore　hydrate　separator　at　different　time.　And　the　results　also　can　in-depth　analysis　the　flow　and　separation　characteristics　of　gas-liquid　flows　in　the　new　hydrate　separator.　This　paper　provides　the　theoretical　basic　for　structure　optimization　of　new　offshore　hydrate　separator　from　the　perspective　of　gas-liquid　flows.
