    • A method and apparatus for compressing rich natural gas is described. The apparatus has a compression stage that has a gas inlet for receiving rich natural gas. The compression stage includes one or more compressors and one or more cooling elements. A pressure vessel is also included for receiving the compressed gas from the compression stage and a liquid outlet is connected between the compression stage and a vessel having a pressure that is less than the pressure in the compression stage. The vessel has a gas outlet connected to the gas inlet. The method includes the steps of subjecting a stream of rich natural gas to a compression cycle to form a compressed gas and a condensate, separating the condensate from the compressed gas, flashing at least a portion of the condensate to a gas and recycling the flashed condensate into the compression cycle.
    • 描述了一种用于压缩富含天然气的方法和装置。 该装置具有压缩级,该压缩级具有用于接收丰富天然气的气体入口。 压缩级包括一个或多个压缩机和一个或多个冷却元件。 还包括用于从压缩级接收压缩气体的压力容器,并且液体出口连接在压缩级与压力小于压缩级压力的容器之间。 容器具有连接到气体入口的气体出口。 该方法包括以下步骤:使富含天然气的气流经受压缩循环以形成压缩气体和冷凝物,将冷凝物与压缩气体分离,将至少一部分冷凝物闪蒸成气体并循环闪蒸的冷凝物 进入压缩循环。
