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.

Device for mixing the contents of a tank comprising a first pipe connecting body arranged on a connecting flange of a tank; a riser pipe extending through the first pipe connecting body into the tank; a mixing pipe extending through said first pipe connecting body into said tank; and a pump whose outlet can be connected at least to the mixing pipe and whose inlet can be connected both to the first pipe connecting body and to the riser pipe. Further a method for mixing the contents of a tank is claimed.

An automatic variable speed eductor recirculation system for metal recycling furnaces having a delacquering chamber and a separate heating chamber. The system includes a recirculation duct between the two chambers, an eductor in the duct, a variable speed blower forcing motive gases into the eductor creating a Venturi that draws VOC's from the delacquering chamber through the eductor, and an infrared opacity sensor proximate the eductor that measures the transparency level of the gases in the eductor. An electronic controller automatically adjusts the blower speed to control the eductor Venturi based upon the transparency level measurements of the opacity sensor.

In one configuration, a system for enriching a liquid with gas-bubbles is disclosed. The system may include at least one reservoir configured to temporarily store the gas-bubble enriched liquid. Each of the at least one reservoir may include an associated inlet port and an associated outlet port fluidically coupled with each other via a liquid-flow line. The system includes one or more pumps configured to cause movement of the liquid along the liquid-flow line, a gas supply feeding a gas (in one configuration, oxygen from a gas concentrator), and a gas-bubble generator provided on the liquid-flow line. The gas-bubble generator may be fluidically coupled to the gas supply to receive gas from the gas supply. The gas-bubble generator may be configured to generate a plurality of individual gas-bubbles of the gas received from the gas supply and mix with the liquid stream flowing via the gas-bubble generator.
