Even when the flow rate at which liquid is supplied varies, the variation in the resistivity of resistivity-adjusted liquid is suppressed by using a simple structure. The hollow fiber membrane module is sectioned into a liquid-phase region and a gas-phase region by hollow fiber membranes. The liquid-phase region receives liquid L whose resistivity is to be adjusted. The gas-phase region receives adjustment gas G used to adjust a resistivity of the liquid L. The module passage pipe communicates with the liquid-phase region of the hollow fiber membrane module, the liquid supply pipe, and the liquid discharge pipe and passes through the hollow fiber membrane module. The bypass pipe communicates with the liquid supply pipe and the liquid discharge pipe and bypasses the hollow fiber membrane module. The bypass pipe includes a laminarization unit including a plurality of thin tubes thinner than the module passage pipe.

Embodiments include systems and methods of in-line mixing of hydrocarbon liquids and/or renewable liquids from a plurality of tanks into a single pipeline based on density or gravity. According to an embodiment, a method of admixing hydrocarbon liquids from a plurality of tanks into a single pipeline to provide in-line mixing thereof includes initiating a blending process. The blending process including continuously blending two or more liquids over a period of time, each of the two or more liquids stored in corresponding tanks, each of the corresponding tanks connected, via pipeline, to a blend pipe thereby blending the two or more liquids into a blended liquid. The method further includes determining a density of each of the two or more liquids to be blended during the blending process. The method includes, in response to a determination that the blend process has not finished and after the passage of a specified time interval, determining an actual blend density of the blended liquid, via a blend sensor connected to the blend pipe, the blended liquid flowing through the blend pipe and in contact with the blend sensor, and the specified time interval less than a total duration of the blending process. The method includes determining an actual blend density of the blended liquid, via a blend sensor connected to the blend pipe, the blended liquid flowing through the blend pipe and in contact with the blend sensor, and the specified time interval less than a total duration of the blending process; comparing the actual blend density with a target blend density; and in response to a difference, based on the comparison, of the actual blend density and target blend density determining a corrected ratio based on each density of the two or more liquids, the actual blend density, and the target blend density and adjusting, via one or more flow control devices, flow of one or more of the two or more liquids, based on the corrected ratio.

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.

The invention provides a multi-compartment container for storing and dispensing separately a plurality of consumable liquids that can be mixed in an accurate and repeatable manner. Each storage compartment within the container encloses a predetermined quantity of a consumable liquid, wherein the first compartment is filled with a first liquid and the other compartments are filled with second and third liquids. The individual storage compartments are structurally merged to form elongated dispensing compartments each with a first end and a second end, wherein a one-way outlet positioned at the first end and a one-way outlet located at the second end permits passage of liquid from the storage compartments into the corresponding dispensing compartments. Upon fully inverting the container, the designated outlet of each dispensing compartment is opened, wherein precise amounts of liquids in the first, second, and third compartments are dispensed at constant volume ratio using gravity.
