Classification: CPC F | IPC F

Claim 0:
1. A method comprising:
adjusting, by a suction throttling valve, flow of a process gas through an inlet flowline;
pressurizing, by a compressor downstream of the suction throttling valve, the process gas;
flowing, by an outlet flowline, the process gas from the compressor;
directing, by an anti-surge flowline branching from the outlet flowline, a first portion of the process gas from the outlet flowline back to the inlet flowline, wherein the anti-surge flowline is connected to the inlet flowline intermediate of the suction throttling valve and the compressor;
adjusting, by an anti-surge control valve, flow of the first portion of the process gas through the anti-surge flowline to the inlet flowline;
directing, by a bypass flowline branching from the anti-surge flowline, a second portion of the process gas from the anti-surge flowline to the inlet flowline, wherein the bypass flowline is connected to the inlet flowline upstream of the suction throttling valve, and the bypass flowline provides an alternative flow path for the second portion of the process gas flowing through the anti-surge flowline to the inlet flowline around the suction throttling valve; and
adjusting, by a bypass control valve, flow of the second portion of the process gas through the bypass flowline to the inlet flowline around the suction throttling valve.
