Mixing of liquids occurs frequently in process engineering. The nature of liquids to blend determines the equipment used. Single-phase blending tends to involve low-shear, high-flow mixers to cause liquid engulfment, while multi-phase mixing generally requires the use of high-shear, low-flow mixers to create droplets of one liquid in laminar, turbulent or transitional flow regimes, depending ...
Demister (vapor), removes liquid droplets from gas streams; Distillation, used for mixtures of liquids with different boiling points; Drying, removes liquid from a solid by vaporization or evaporation; Electrophoresis, separates organic molecules based on their different interaction with a gel under an electric potential (i.e., different travel)
Energy-separating agents are used for creating a second phase (immiscible of different composition than the first phase), they are the most common techniques used in industry. For example, leads the addition of heat (the separating agent) to a liquid (first phase) to the formation of vapor (second phase). Mass-separating agents are other chemicals.
Laboratory-scale liquid-liquid extraction. Photograph of a separatory funnel in a laboratory scale extraction of 2 immiscible liquids: liquids are a diethyl ether upper phase, and a lower aqueous phase. Soxhlet extractor. Extraction in chemistry is a separation process consisting of the separation of a substance from a matrix. The distribution ...
Solid phase samples can be ionized through methods such as field desorption, plasma-desorption, fast atom bombardment, and secondary-ion ionization. Liquids with the analyte dissolved in them, or solutions, can be ionized through methods such as matrix-assisted laser desorption, electrospray ionization, and atmospheric-pressure chemical ionization.
Solid-phase microextraction (SPME), is a solid phase extraction technique that involves the use of a fiber coated with an extracting phase, that can be a liquid or a solid , which extracts different kinds of analytes (including both volatile and non-volatile) from different kinds of media, that can be in liquid or gas phase.

Filters may be used for the purpose of removing unwanted liquid from a solid residue, cleaning unwanted solids from a liquid, or simply to separate the solid from the liquid. There are many different methods of filtration; all aim to attain the separation of substances. Separation is achieved by some form of interaction between the substance or ...
Liquids with small proportion of suspended solids. [13] Solid-liquid mixture leaving a three-phase reactor is separated using a conical plate centrifuge. The solid is sent to the solids separation system whereas the liquid is sent to the liquid separation system. [13] Product. Low moisture content in the wet cakes. [14]
