An intelligent magnetic microfluidic concentrator employs a technique of feeding ores circumferentially and allowing tailings to overflow centrally upward. The intelligent magnetic microfluidic concentrator comprises a sorting system consisting of an ore feeding chute, an overflow chute, an overflow tank, a sorting tank, and a magnetic system, the overflow tank is disposed at an upper portion of the sorting tank, the ore feeding chute is disposed at the top of the overflow tank, the ore feeding chute feeds an ore slurry to the upper portion of the sorting tank circumferentially along an inner wall of the sorting tank, and the tailings overflow out upward from the overflow tank disposed centrally and located at the upper half portion of the sorting tank. A magnetic microfluidic concentrator and a complete set of beneficiation equipment are also provided.

A collection and concentration system including a separation tank having a plurality of distribution arms configured to separate and recover oil, water, and sediment or sand from an inflowing mixture of the same. The distribution arms are connected to and in fluid communication with a downcomer section of a center column that is vertically arranged in the separation tank. The distribution arms extend radially toward a sidewall of the tank and include tangential discharge nozzles that are tangentially directed toward the sidewall. Inflowing mixture directed tangentially against the sidewall is directed in a downward, helical manner that assists in the separation and recovery of oil, water, and sediment from the inflowing mixture.

A separation tank for the separation of a mixture of oil, gas, water, and solids obtained from an oil field includes distinct regions vertically located within the tank interior where constituent components of the mixture can collect. The inflowing mixture may be directed to a vertical column extending inside the separation tank and can be introduced to the tank interior through a swirl vane diffuser configured to impart a helical direction to the inflowing mixture that assist separation of the mixture component. To further facilitate separation of oil from the mixture, the separation tank may be operatively associated with an aeration system configured to generate and introduce an aerated liquid to the tank interior. Gas dissolved in the aerated liquid may form microbubbles that can naturally adhere to the oil and solids separate it from the mixture which can improve the quality of the water.

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.

A gas separator, gas separation system, and method for separating gas from drilling cuttings by actively maintaining a liquid seal of liquid in a lower portion of a separation vessel by controlling an introduced amount of the liquid admitted to the separation vessel as a removed amount of the liquid is removed from the separation vessel and by promoting agitation of the drilling cuttings in the liquid in an agitation chamber within the lower portion of the separation vessel to aid removal of the drilling cuttings along with the removed amount of the liquid.

The invention relates to a method for clarification of raw green liquor in a sedimentation tank. According to the invention is a part of dregs separated in the sedimentation tank recirculated back into the inflow of raw green liquor, and preferably after passing the dregs through at least one turbulence generator (30, 31) that could break up larger dregs particles into smaller dregs particles, and thus create larger total surface on the dregs particles, improving sedimentation rate in the sedimentation tank. In a preferred embodiment is the recirculated dregs added into the flow of raw green liquor before a flocculant is added into the flow of raw green liquor and mixed recirculated dregs.

A system for treating liquids and solutions for separating components thereof, the system including a treatment vessel having a treatment chamber therein, a device for generating a gas-infused liquid under elevated pressure, and a device for stabilizing the gas-infused liquid such that most of the gas infused into the liquid by the device for generating a gas-infused liquid will remain in the liquid if pressure of the liquid is reduced to atmospheric pressure, and for flowing the stabilized gas-infused liquid into the treatment chamber so as to form a liquid layer including the stabilized, gas-infused liquid in the treatment chamber. The treatment vessel includes a discharge port through which some of the stabilized, gas-infused liquid in the liquid layer may be discharged from the treatment vessel, the withdrawn liquid is infused with an additional amount of the gas, again stabilized, and again flown the liquid into the treatment chamber.

Systems and methods of removing coke/tar from water in a quench water recycling loop of a steam cracker quench system are disclosed. The systems include a quench water separator that has a feed calming compartment for reducing eddies in feed to the quench water separator. The feed calming compartment is defined, at least in part, by a perforated baffle in the quench water separator. The methods include the use of the quench water separator with the perforated baffle and the calming compartment to separate coke/tar from quench water in the quench water recycling loop.

Settling devices for separating particles from a bulk fluid with applications in numerous fields. The particle settling devices include a first stack of cones with a small opening oriented upwardly or downwardly. Optionally, the settling devices may include a second stack of cones with a small opening oriented downwardly or upwardly. The cones may be concave or convex. These devices are useful for separating small (millimeter or micron sized) particles from a bulk fluid with applications in numerous fields, such as biological (microbial, mammalian, plant, insect or algal) cell cultures, solid catalyst particle separation from a liquid or gas and waste water treatment.

A cyclonic inlet diverter for initiating the separation of a multi-phase inlet fluid flow comprises an enclosed tubular body mounted crosswise within a larger separator vessel. The inlet diverter includes a splitter plate positioned within a center portion of the tubular body and configured to split the inlet flow into a first stream and a second stream, and a swirl plate positioned on each side of the splitter plate with angled surfaces configured to increase the cyclonic motion of the first and second streams within the tubular body. The inlet diverter further includes elongate apertures formed through bottom sidewall portions of the tubular body on each side of the splitter plate, an axial aperture formed through opposing end caps of the tubular body, and at least one radial aperture formed through lateral sidewall portions of the tubular body proximate each opposing end cap.
