Apparatus for mixing polymer, the apparatus comprising (i) a mixer housing including an internal chamber, said internal chamber having first and second sections in fluid communication with each other through a passageway; (ii) a first ram received in said first section; and (iii) a second ram received in said second section, where the apparatus is adapted to receive a composition including polymer within said internal chamber and move said composition between said first and second chambers through said passageway by operation of said first and second rams.

A mobile cement batch mixing plant includes at least one slurry tank, a cement storage tank, at least one slurry pump and at least one clean pump supported on a transportable frame. The slurry tanks and cement storage tank are connected by a plumbing system. The flow of water and cement slurry between the tanks and within the plumbing system is controlled by a series of valves and pump controls. A cement slurry is formed by adding water and cement to the slurry tank through a fluid vortex within the slurry tank. The cement slurry can be pumped out of the slurry tank into a well.

An apparatus includes a housing with an inlet for a pasty product to be aerated and an outlet for the aerated product. The apparatus includes at least a first set of a rotor and a stator and a second set of a rotor and a stator. The apparatus further includes a gas injector for injecting, upstream of the first set of the rotor and the stator, a gas into the pasty product to be aerated. The apparatus further includes an intermediate mixing chamber provided in the housing between the first and the second sets of the rotor and the stator . A secondary product introduction member protrudes into the intermediate mixing chamber so as to issue into the intermediate mixing chamber. A method for aerating a pasty product is also provided.

A method and a system for sequestering carbon dioxide (CO.sub.2) while producing freshwater are provided. An exemplary method includes producing saline water from a saline aquifer, desalinating at least a portion of the saline water, producing freshwater and waste brine, mixing waste CO.sub.2 with the waste brine forming a brine/CO.sub.2 mixture, and injecting the brine/CO.sub.2 mixture into the saline aquifer.

A powdery-material mixing and feeding system is configured to feed a machine configured to execute a post process with mixed-powdery materials obtained by mixing a first powdery material and a second powdery material discharged from powdery-material feeding devices at a required ratio, wherein when a flow rate of the first powdery material discharged from the first powdery-material feeding device departs from a target value by a predetermined amount or more, a controller increases or decreases the flow rate of the second powdery material discharged from the second powdery-material feeding device such that the ratio of the first powdery material to the second powdery material contained in the mixed-powdery materials is kept within a desired range.

An insert assembly for a foam generating device includes a first insert and a second insert with a channel defined therethrough. Inserts may be formed by two shell halves that are coupleable to one another to define the channel. A plurality of ribs extends along an interior surface of the channel. Pad structures defined by porous media are provided in the channel and gripped by the plurality of ribs. The pads receive cleaning solution passing through the channel and cause foam to be generated by breaking-up the cleaning solution and agitating. The ribs may be arranged horizontally relative to a longitudinal axis of the insert assembly and retain the pads within the device. Inserts may be arranged in series along a longitudinal axis of the foam generating device with the pad structures arranged within the channel.

A single stage clarifier and mixing assembly includes a housing, a mixing section within the housing and a clarifier section within the housing. The mixing section includes a mixing chamber having (a) an inlet, adapted for delivering an inlet stream to the mixing chamber, at an upper end, and (b) a mixing section outlet at a lower end. The clarifier section extends concentrically around the mixing section. The single stage clarifier and mixing assembly also includes an agitator adapted for mixing the inlet stream in the mixing chamber.

Herein disclosed is a method of producing value-added product from light gases, the method comprising: (a) providing light gases comprising at least one compound selected from the group consisting of C1-C6 compounds and combinations thereof; (b) intimately mixing the light gases with a liquid carrier in a high shear device to form a dispersion of gas in the liquid carrier, wherein the dispersion is supersaturated with the light gases and comprises gas bubbles at least some of which have a mean diameter of less than or equal to about 5 micron(s); (c) allowing the value-added product to form and utilizing vacuum to extract unreacted light gases from the liquid carrier; (d) extracting the value-added product; wherein the value-added product comprises at least one component selected from the group consisting of higher hydrocarbons, hydrogen, olefins, alcohols, aldehydes, and ketones. A system for producing value-added product from light gases is also disclosed.

A flow-through cavitation device having an elongated housing with an inlet and an outlet. An inner annular body and an outer annular body are concentrically and nestingly disposed in the elongated housing. The outer annular body is fixed relative to the housing and the inner annular body is rotatable about a longitudinal axis of the housing. Each annular body has a plurality of channels that pass therethrough. Rotation of the inner body relative to the outer body provides for selective alignment or misalignment of the plurality of channels to control fluid flow from the inlet to the outlet. The device may have a plurality of pairs of inner and outer annular bodies as described.
