A multi-tiered precision powder coating batch system configured to enable simultaneous preparation of a first and second batch of powder coatings. The multi-tiered precision powder coating batch system including a plurality of storage bins configured to store a corresponding plurality of raw materials for preparation of batches of powder coatings, each of the storage bins including an automated dispenser configured to dispense a desired quantity of raw material within the storage bins into a corresponding first raw material container located on a first tier, and a second raw material container located on a second tier, and a robotic arm configured to sequence a transfer of the raw material contents of the first tier raw material containers into a first tier mixing container for preparation of a first batch of a powder coating, and to sequence a transfer of the raw material contents of the second tier raw material containers into a second tier mixing container for a simultaneous preparation of a second batch of a powder coating.

A method for controlling the saturation level of gas in a liquid discharge includes obtaining temperature and pressure measurements of a solvent in a mixing vessel and obtaining a pressure measurement of a source feedstock in a feedstock tank, correlating the temperature and pressure measurements of the solvent to baseline data to generate a theoretical uptake rate for the source feedstock into the solvent and a theoretical flow rate of the source feedstock into the mixing vessel, and determining a required opening setting for a feedstock valve in the feedstock input line in order to achieve a desired liquid displacement in the mixing vessel. The method includes determining an uptake duration and achieving an uptake displacement equivalent to the reverse of the desired liquid displacement. The method includes generating a valve operating control law for how the feedstock valve should function in a cycle.

Embodiments of the present invention include a method and system for blending multi-component granular compositions such as proppant used in hydraulic fracturing in well drilling. The system includes the control and management of an on-site storage system for each of the components, regulating the delivery of specified quantities of each component to a blender, and coordinating the flow of materials into and out of the blender.

In accordance with presently disclosed embodiments, systems and methods for efficiently handling dry additives to be mixed with bulk material in a blender are provided. The systems may include a support structure used to direct bulk material from one or more portable containers on the support structure to a first outlet location, and a combined metering/transferring system for directing dry additives from another portable container to a second outlet location. Specifically, the metering/transferring system may output a metered flow of dry additives to the blender mixer to be combined with bulk material that is released from the portable containers. The metering/transferring system may utilize a gravity feed outlet coupled to a metered screw or other conveying device to move the dry additive from the portable container to the second outlet location.

A system and an associated method for starting up stirring machines in a sediment in a controlled manner are provided, which system has the following: a container for receiving materials to be processed; a stirring device with stirring blades for stirring the materials to be processed in the container; a purging device; and a device for operating stirring machines. The purging device is arranged in such a way and set up so as to feed a medium for purging to a deposited sediment. Furthermore, a controller is provided which initiates controlled re-starting of stirring machines after purging.

A fluid mixing system including, an upper assembly, comprising a submersible pump housed therein; a base assembly connected to the upper assembly, the base assembly comprising one or more diffusers connected to opposing end portions of the base assembly; and a fluid path fluidly connecting the upper assembly and base assembly, wherein the fluid path extends from an outlet of the submersible pump to the one or more diffusers, and wherein the one or more diffusers are configured to provide a fluid outlet from the fluid path to create movement of fluid within a fluid reservoir.

A homogenizer for homogenously blending a feedstock includes a separator, an agitator and a hopper integrated as a single unit in a common housing. The separator receives a material feed, in the form of a fluid medium carrying a composite feedstock, and separates the composite feedstock from the fluid medium. The agitator receives the separated composite feedstock from the separator, and mixes the composite feedstock to yield the homogenously blended feedstock. The hopper receives the homogenously blended feedstock from the agitator and holds the homogenously blended feedstock for release to either a processing machine or a storage container. The homogenizer is controlled by one or more control units that use signals received from a sensor in the hopper to control the delivery of a material feed to the homogenizer, and the flow of feedstock therethrough.
