A recently granted patent (Publication Number: US12011697B2) discloses an innovative in-line liquid mixing system designed to blend various hydrocarbon liquids, petroleum liquids, or renewable liquids from multiple tanks into a single pipeline. The system comprises a complex network of tanks, headers, pumps, flow meters, spillback pipes, blend pipes, and controllers to facilitate the efficient admixing of liquids. The system includes spillback loops with control valves to adjust flow rates, blend pipes to create a blend flow, and blend meters to measure the flow rate of the blend. Additionally, the system incorporates differential pressure transmitters and controllers to regulate the flow rates and ratios of the liquids being mixed, ensuring precise blending according to set parameters.

Furthermore, the patent also outlines a method for implementing the in-line liquid mixing system, detailing the steps involved in initiating a blending process, determining liquid densities, measuring flow rates, and adjusting control valves to achieve the desired blend ratio. The method involves recirculating liquids through spillback loops, monitoring differential pressures, and making real-time adjustments to drive the flow rates towards target ratios. By following this method, operators can effectively blend hydrocarbon or renewable liquids from different tanks into a single pipeline, ensuring consistent and accurate mixing. Overall, the patent highlights a sophisticated system and method for in-line liquid mixing, offering a comprehensive solution for industries dealing with the blending of various liquid products.
