METHOD AND SYSTEM FOR LOAD CONTROL OF A RECIPROCATING COMPRESSOR

Controlling the capacity of a compression system in response to variable incoming gas feed by: i) controlling the capacity of a compression system in response to variable incoming gas feed selectively varying a capacity of a first subset of one or more compressor banks by continuously varying a capacity of one or more cylinders of one or more reciprocating compressor stages of the one or more compressor banks of the first subset between a maximum capacity and a minimum capacity; and/or ii) selectively varying the capacity of a second subset of the one or more compressor groups by fully loading or fully unloading one or more cylinders of one or more reciprocating compressor stages of the compressor groups of the second subset, wherein the first subset and the second subset are mutually exclusive. 响应于可变传入气体进料而通过以下方式来控制压缩系统的容量：i)通过连续地使第一子集的一个或多个压缩器组的一个或多个往复式压缩器级的一个或多个缸的容量在最大容量和最小容量之间变化来选择性地使所述一个或多个压缩器组的所述第一子集的容量发生变化；和/或ii)通过完全加载或完全卸载第二子集的压缩器组的一个或多个往复式压缩器级的一个或多个缸来选择性地使所述一个或多个压缩器组的所述第二子集的容量发生变化，其中第一子集和第二子集是互斥的。
