This invention discloses a system and process for flexibly controlling liquid delivery and recirculation, relating to the field of fuel delivery system technology. The system includes a first booster pump, a second booster pump, a first fuel storage tank, a second fuel storage tank, a fuel recirculation pipeline, and a booster pipeline. The first and second fuel storage tanks are connected to the inlets of the first and second booster pumps via the booster pipeline, and the outlets of the first and second booster pumps are connected to the first and second fuel storage tanks via the fuel recirculation pipeline. The system and process for flexibly controlling liquid delivery and recirculation in this invention enables flexible control of fuel delivery and recirculation processes. By controlling the delivery of alcohol-based fuels, it achieves risk prevention, simplification, and temperature control, and allows for easy switching to meet usage requirements. It also reduces the need for fuel booster pumps and allows for redundant configuration, reducing the risk of modifying the operating equipment.
