Реферат: A compression system (100) comprises a compressor (110), an inlet duct (130), a throttling valve (140) installed in the inlet duct (130), an outlet duct (150), an anti -surge valve (160) fluidly coupling the outlet duct (150) with a portion of the inlet duct (130) downstream of the throttling valve (140) and a recycle valve (170) fluidly coupling the outlet duct (150) with a portion of the inlet duct (130) upstream of the throttling valve (140). Keeping the recycle valve (170) open, the anti -surge valve (160) closed and the throttling valve (140) partially closed allows lowering the pressure of the flow entering the compressor (110) during its start-up.
