Claim 0:
1. A compression system having a system inlet and a system outlet, the compression system comprising:
a compressor having a compressor inlet and a compressor outlet;
an inlet duct fluidly coupling the compressor inlet with the system inlet, the inlet duct comprising a first duct portion and a second duct portion, each having a first end and a second end, the first end of the first duct portion fluidly coupled with the system inlet and the first end of the second duct portion fluidly coupled to the compressor inlet;
an outlet duct fluidly coupling the compressor outlet with the system outlet;
a throttling valve fluidly coupling a second end of the first duct portion and a second end of the second duct portion;
an anti-surge valve fluidly coupling the outlet duct with the second duct portion;
a recycle valve fluidly coupling the outlet duct with the first duct portion; and
a control unit arranged to control the throttling valve, the recycle valve, and the anti-surge valve,
wherein the throttling valve is configurable in an open condition and in at least one partially closed condition, and
wherein the control unit is configured to maintain the anti-surge valve in a closed condition and the recycle valve in an open condition during a start-up of the compressor.
