A battery paste mixer condensation assembly includes a duct, a condenser, a basin, and a pipe. The duct is in fluid communication with a battery paste mixer. Exiting gas from the battery paste mixer can travel through the duct. The condenser is situated downstream of the duct. The basin is situated near the condenser. Condensed liquid from the condenser is deposited in the basin. The pipe is in fluid communication with the basin and is in fluid communication with the battery paste mixer. Deposited liquid in the basin can travel from the basin and to the battery paste mixer by way of the pipe.

The disclosure provides a method for preparing an amphiphilic lignin nanomaterial based on pulping black liquor, an amphiphilic lignin nanomaterial, and an oil sludge detergent. In the disclosure, physical treatments such as ball milling and high-pressure jet homogenization treatment are conducted on alkali lignin at the early stage to adjust the molecular weight and size of alkali lignin and thus to give alkali lignin nanoparticles with uniform particle sizes; and on this basis, a chemical treatment such as alkylation grafting modification is conducted to give amphiphilic lignin nanoparticles with both hydrophilicity and lipophilicity. Due to the nano-size effect, the amphiphilic lignin nanomaterial has a significantly-increased specific surface area (SSA) and effectively-improved surface properties, which can reduce the oil-water interfacial tension, and emulsify the crude oil and peel off the crude oil from the surface of rock particles, so as to achieve the purpose of oil-solid separation.

An inclined belt conveyor capable of mixing particulate material, such as agricultural seed or fertilizer. Inserting a plurality of mixing baffles into the stream of the particulate material induces a backflow of the particulate material. In the case of wet, freshly treated plant seed, this backflow causes a mixing, polishing, and drying of the plant seed. The mixing distributes the seed treatment into an even coat by rubbing the individual seeds of the seed flow stream together. The inclined belt conveyor may also be used to blend multiple varieties or types of particulate material. The mixing baffles are oriented to induce backflow and sideways lateral movement and may incorporate a passage to allow increase particulate material flow rate. The mixing baffles can selectively deploy between an angle of 20 degrees to 70 degrees to enable the mixing inclined belt conveyor to have a transfer-speed-maximizing mode and a mixing mode.

A system for preparing a polymeric mixture includes: a containment device configured to distribute dry polymeric materials; a receiving chamber in fluid communication with the containment device; a wetting bowl; a dispersing channel; and a mixing chamber connected to the dispersing channel. A method of preparing a polymeric mixture includes distributing water and dry polymeric materials through the various components of the system and mixing the materials with the mechanical mixing device.

A stream of seed may be maintained at a metered flow rate through multiple stages of a treatment process. These multiple stages include dispensing, first application of fluid, second application of fluid, and seed transport. Seed transport may be accomplished through a conveyor configured to maintain the metered flow rate while providing static mixing, drying, and conditioning of the treated seed. The metered stream of seed may be treated within a first treatment applicator where a first wet treatment is applied, transferred through the incline conveyor, and treated again within a second treatment applicator where a second wet treatment is applied. Overtreating in multiple stages may layer consecutive seed treatments around the treated seed. A predetermined amount of seed treatment may be applied to the coated seed based on the metered flow rate established. Maintaining the metered flow rate through multiple stages eliminates the need for multiple metering steps.

A wet frac-sand well site delivery system is a process and method of storing, measuring and regulating the percent solids or PPA (pounds of proppant added) in a sand slurry. The wet sand delivery system is a closed loop, on-site storage system that can receive and store wet frac-sand. The wet sand delivery system takes the wet sand directly from the wash plant and transports it to a wet sand storage pit. From the wet sand storage pit, the sand is pumped directly to a blender or regulator for mixing into a sand slurry for subsequent delivery to a frac pump.
