    • Method and apparatus for controlling one or more first compressors (12), through which a compressor feed stream (10) is passed. At least one throttling valve (32) is provided downstream of a compressor recycle line (22), which is provided around the or each first compressor (12) and includes an in-line first recycle valve (24). Sometimes, at least a fraction of the compressor feed stream (10) is selectively allowed to bypass the or each first compressor (12) and the at least one throttling valve, via a bypass line (60). At least one of the throttling valves (32) is automatically controlled using the measurement values of at least one pressure and at least one flow of the group consisting of : the pressure (Pl) of the compressor feed stream (10), the flow (Fl) of the compressor feed stream (10), the pressure (P2) of the first compressed stream (20) and the flow (F2) of the first compressed stream (20). A first compressor controlled this way may be used in a method of cooling an initial hydrocarbon stream (100).
    • 用于控制一个或多个第一压缩机(12)的方法和装置,压缩机进料流(10)通过该压缩机通过。 至少一个节流阀(32)设置在压缩机循环管线(22)的下游,该压缩机循环管线设置在该第一压缩机(12)周围或每个第一压缩机(12)周围,并包括一个在线的第一再循环阀(24)。 有时,选择性地允许压缩机进料流(10)的至少一部分经由旁路管线(60)绕过或每个第一压缩机(12)和至少一个节流阀。 使用至少一个压力和至少一个流量的测量值来自动控制至少一个节流阀(32),该流量包括:压缩机进料流(10)的压力(P1),流量 压缩机进料流(10)的压力(F1),第一压缩流(20)的压力(P2)和第一压缩流(20)的流量(F2)。 以这种方式控制的第一压缩机可以用于冷却初始烃流(100)的方法。
