摘要： Disclosed are apparatus and methods for preparing wellbore viscous treatment gels from dry polymer and water. The apparatus includes an eductor which slurries dry polymer with water, at least two input tubes, wherein one input tube is connected with the eductor, and another to a water source. The apparatus also includes a mixing chimney connected to the input tubes. The mixing chimney includes a lower input section with inlets connected to the input tubes wherein a jet of metered dilution water is applied at high pressure to the incoming polymer-water slurry stream. This mixture is then accelerated in a circular, and preferably upward, motion where it is sheared against the wall of a central section of the chimney, without the use of an impeller. The chimney further includes an output section that comprising holes circumferentially located, through which the mixture passes from the central section and into a hydration tank. The mixture exiting the chimney is polymer-water gel which is essentially fully mixed and de-aerated, and at least partially hydrated.

摘要： An aeration system for circulating an aerating fluid through a chemical composition within a container. The aeration system is closed-loop such that the aeration fluid is supplied by a fluid supply system to the interior of a container to aerate the chemical composition therein. The aeration fluid is returned to the fluid supply system for subsequent redelivery to the container. A filtering mechanism may be employed to remove large particulate matter from the aeration fluid prior to flowing back to the fluid supply system. The aeration process improves the flowability of the chemical composition thus facilitating the transferring and/or discharging of the chemical composition from the container. The aeration process may occur during transport, prior to discharging, and/or during a discharging or transferring operation.
