A method for controlling flow in a Natural Gas Liquids (NGL) extraction system includes determining an operational characteristic of one or more residue gas compressors operating within the NGL extraction system and calculating a rate of closure for one or more throttle valves associated with the one or more residue gas compressors based on the operational characteristic determined. When a process upset in the NGL extraction system is detected, the one or more throttle valves are closed at the calculated rate of closure in response to detecting the process upset.
