Apparatus and methods for separating blood components are disclosed in which an apparatus for separating blood generally includes a tube defining a channel and configured for receiving a quantity of blood and a float contained within the tube and having a density which is predefined so that the float is maintained at equilibrium between a first layer formed from a first fractional component of the blood and a second layer formed from a second fractional component of the blood. Upon completion of the centrifugation, the first layer may be removed from the tube while the float isolates the second layer from the first layer.

Provided is a process of stabilizing active ingredients of plant materials in an aqueous suspension, the process including: extracting one or more active ingredients of a plant material using an extraction solvent, wherein the extraction of the one or more active ingredients of the plant materials comprises: transferring the plant material into a temperature-controlled reactor; adding the extraction solvent to the temperature-controlled reactor, thereby producing an eluant from the plant material; incubating the eluant at a first selected temperature for a pre-determined duration of time; and running the eluent through a filtration process to obtain an extractant solution filtrate and a separated solid plan material product; encapsulating the one or more active ingredients in one or more nanoparticles; and dispersing the one or more nanoparticles in an aqueous suspension.

Disclosed herein are systems and methods from processing flue gas desulfurization (FGD) gypsum feedstock and ash feedstocks, either separately or together. FGD gypsum conversion comprises reacting FGD gypsum (calcium sulfate) feedstock or phosphogypsum, in either batch or continuous mode, with ammonium carbonate reagent to produce commercial products comprising ammonium sulfate and calcium carbonate. A process to separate the impurities and convert the calcium carbonate to a pure precipitated calcium carbonate is disclosed. These impurities include a concentrate of valuable Rare Earth Elements, and radioactive thorium and uranium. A process to convert calcium sulfite to calcium sulfate using oxygen and a catalyst is also disclosed. Ash conversion comprises a leach process followed by a sequential precipitation process to selectively precipitate products at predetermined pHs resulting in metal hydroxides which may be converted to oxides or carbonates. The processes may be controlled by use of one or more processors.

A method is provided for preventing or reducing the formation of monochloropropanediols (MCPDs) or monochloro-propanediol esters (MCPDEs) in triacylglyceride oil, comprising the steps: (a) concentrating insoluble components in liquid starting triacylglyceride oil by (i) applying a centrifugational force on the triacylglyceride oil whilst maintaining the triacylglyceride oil above its melting temperature; and/or (ii) allowing the insoluble components to settle by gravitational force whilst maintaining the triacylglyceride oil above its melting temperature; (b) separating the triacylglyceride oil from the insoluble components; (c) optionally applying additional refining steps and (d) applying heat treatment to the triacylglyceride oil. A purified triacylglyceride oil obtainable by the method of the invention is also provided.

Disclosed herein are methods for isolating target cells from blood, involving mixing in an open container an undiluted blood sample having a volume of 10 ml or less, and binding agents, wherein each binding agent comprises (A) a primary binding agent comprising an agent capable of binding to at least one cellular epitope on target cells in the undiluted blood sample, (B) a first linker bound to the primary binding agent, to generate binding agent-attached target cells in the undiluted blood sample; contacting the binding agent-attached target cells in the undiluted blood sample with a plurality of buoyant reagents that include a second linker capable of binding to the first linker to generate an undiluted buoyant reagent-attached target cell mixture; diluting the undiluted buoyant reagent-attached target cell mixture by at least 20% to produce a diluted buoyant reagent-attached target cell mixture; applying a vectorial force, such as centrifugal force, to the diluted buoyant reagent-attached target cell mixture to generate a stratified diluted buoyant reagent-attached target cell mixture; removing the buoyant reagent-attached target cells from the stratified diluted buoyant reagent-attached target cell mixture; and isolating the target cells from the buoyant reagent-attached target cells.

The present disclosure provides, in some embodiments, devices, methods, and kits for purifying extracellular vesicles (EVs) using size exclusion chromatography in tandem with cation exchange chromatography, which can be referred to as dual-mode chromatography (DMC).

Systems and methods are provided for separation of particles and/or asphaltenes from heavy hydrocarbon fractions. The heavy hydrocarbon fraction can correspond to a feed including particles or a processing effluent that includes particles. If the heavy hydrocarbon fraction is mixed with lower boiling fractions, a separation can be performed to reduce or minimize the amount of hydrocarbons that are present in the heavy hydrocarbon fraction. The heavy hydrocarbon fraction can then be mixed with a sufficient amount of a separation solvent to cause a phase separation. One phase can correspond to the separation solvent plus a portion of the hydrocarbons. The other phase can correspond to hydrocarbons rejected by the separation solvent plus the particles from the heavy hydrocarbon fraction. The phases can then be separated from each other using a solids-liquid centrifugal separator.

An exhaust gas cleaning system comprises a first sub system including a scrubber unit comprising a scrubber arranged to wash the exhaust gas with a scrubber fluid, and a centrifugal separator arranged in communication with the scrubber unit for receiving the scrubber fluid after washing and separate it into a first and a second fraction, which second fraction is more polluted than the first fraction. The exhaust gas cleaning system further comprises a second sub system including a membrane filter arranged in communication with the centrifugal separator for receiving the first fraction output from the centrifugal separator and separating it into a third and a fourth fraction, which fourth fraction is more polluted than the third fraction. A method for cleaning exhaust gas onboard a ship involves cleaning an exhaust gas onboard a ship.

The present system is for simultaneous recovery of purified water and dissolved solids from impure high TDS water (1) which is achieved in a single step and eliminates the use of external thermal energy for making the system significantly efficient. It eliminates the use of boiler, cooling tower that reduces the overall capital cost and continuous requirement of external thermal energy for making system efficient. The simultaneous recovery of the purified water and solids from high TDS input effluent reduce the energy intensity of the system. Said system provides a vacuum system as heat pump which enables the system to be self-sufficient in thermal energy requirements for evaporation process and reduces GHG emissions significantly.

A method and system is provided for treating waste generated from manufacturing operations including at least one of Printed Circuit Boards Fabrication (PCB FAB), General Metal Finishing (GMF), semiconductors manufacturing, chemical milling, and Physical Vapour Deposition (PVD). The method and system are used to create zero liquid discharge recycling.
