    Abstract: A system for mixing acid and water can include a tank for holding acid, an acid pump for pumping acid out of the tank, an acid flow meter, an acid control valve, a water pump for pumping water, a water flow meter, a water control valve, a flush valve to selectively flush the system with water, and a controller to monitor the flow meters and control the pumps and the valves. The acid control valve and/or the water control valve can be an electronically controlled valve. The flush valve can be an electronically controlled valve to selectively permit water to flow from downstream of the water pump to upstream of the acid pump. The acid control valve, the water control valve, the flush valve, or any combination thereof can be throttled by the controller to control flow therethrough.

    Abstract: Methods and systems of admixing hydrocarbon liquids from a plurality of tanks into a single pipeline thereof. The system may include two or more tanks positioned at a tank farm each containing a hydrocarbon liquid therein. The system may include two or more first main pipes, each connected to one of the tanks. The system may include two or more main valves, each connected to one of the first main pipes. The system may include two or more second main pipes each connected to a corresponding main valve. The system may include two or more mixing jumpers, each connected to a corresponding first main pipe, each mixing jumper to, when a corresponding main valve is closed, control hydrocarbon liquid. The system may include a mixing pipe, connected to the second main pipes and the mixing jumpers, configured to transport hydrocarbon liquid from one or more of the tanks.

    Abstract: Methods and systems of admixing hydrocarbon liquids from two or more sets of tanks into a single pipeline to provide in-line mixing thereof. In an embodiment of the in-line mixing system, hydrocarbon liquids stored in at least one tank of each of two or more sets of tanks positioned at a tank farm are blended into a blend flow pipe via in-line mixing and the blended mixture is pumped through a single pipeline. In one or more embodiments, the in-line mixing system employs a separate spillback or recirculation loop that is fluidly connected to each set of the two or more sets of tanks to control the flow of the hydrocarbon fluid/liquid from each set of tanks to the blend flow pipe. Associated methods of operating one or more embodiments of the system include regulation of spillback or recirculation loop flow rate and/or pressure to drive the actual blend ratio towards a desired blend ratio.

    Abstract: The invention discloses a multifunctional microfluidic detection chip. The detection chip comprises a chip body, on which a sample injection chamber, a sample quantitative chamber, a sample overflow chamber, a diluent storage chamber, a diluent quantitative chamber, a diluent overflow chamber, a quantitative mixing chamber, a reaction chamber and vent holes are disposed; a sample to be detected is injected into the sample injection chamber, and enters the sample quantitative chamber through a microfluidic channel, and the excess reaction sample enters the sample overflow chamber, a diluent in the diluent storage chamber enters the diluent quantitative chamber through a microfluidic channel, and the excess diluent enters the diluent overflow chamber; the reaction chamber includes one or more reaction cavities and a sample blank cavity; after the sample in the sample quantitative chamber is mixed with the diluent in the diluent quantitative chamber uniformly in the quantitative mixing chamber, mixed liquid enters the reaction cavities through microfluidic channels and reacts with a reaction reagent for detection, and enters the sample blank cavity at the same time as a sample blank for detection. The invention can effectively reduce the sample consumption, improve the accuracy of the detection results, and simultaneously detect multiple indicators.
