an inlet separator system configured to receive production fluid for separation of liquids therefrom to recover gas lift gas, the inlet separator system comprising at least one separator vessel for separation of liquids from gas, the at least one separator vessel including a production inlet to receive production fluid from a well, a gas lift gas outlet for connection with a gas lift gas compressor system, and a liquid outlet;

a charge system including a high pressure (HP) leg for holding an HP portion of fluid and a low pressure (LP) leg for holding an LP portion of fluid, a liquid inlet for selective communication with the liquid outlet of the inlet separator to receive liquids; and

a sump system for holding liquids from at least one of the inlet separator system and the charge system, the sump system comprising a sump vessel arranged for selective communication with the charge system via a vapor line to transfer vaporous release to the charge system; and

a control system for operation to conduct selective communication of fluids, wherein the control system is configured to selectively communicate the sump system with at least one of the inlet separator system and the charge system to transfer liquids to the sump system.
