  2. List of purification methods in chemistry - Wikipedia

    en.wikipedia.org/wiki/List_of_purification...

    In a laboratory setting, mixture of dissolved materials are typically fed using a solvent into a column packed with an appropriate adsorbent, and due to different affinities for solvent (moving phase) versus adsorbent (stationary phase) the components in the original mixture pass through the column in the moving phase at different rates, which ...

    Robotic Hydrodemolition in Folkestone, UK. Hydrodemolition of concrete exposing the rebar.. Hydrodemolition (also known as hydro demolition, hydroblasting, hydro blasting, hydromilling, waterblasting, and waterjetting) is a concrete removal technique which utilizes high-pressure water, often containing an abrasive material, to remove deteriorated and sound concrete as well as asphalt and grout.

  4. Hydrodeoxygenation - Wikipedia

    en.wikipedia.org/wiki/Hydrodeoxygenation

    Hydrodeoxygenation (HDO) is a hydrogenolysis process for removing oxygen from oxygen-containing compounds. Typical HDO catalysts commonly are sulfided nickel-molybdenum or cobalt-molybdenum on gamma alumina.

  6. Degassing - Wikipedia

    en.wikipedia.org/wiki/Degassing

    Gases are removed for various reasons. Chemists remove gases from solvents when the compounds they are working on are possibly air- or oxygen-sensitive (air-free technique), or when bubble formation at solid-liquid interfaces becomes a problem. The formation of gas bubbles when a liquid is frozen can also be undesirable, necessitating degassing ...

  8. Wet chemistry - Wikipedia

    en.wikipedia.org/wiki/Wet_chemistry

    Wet chemistry is a form of analytical chemistry that uses classical methods such as observation to analyze materials. The term wet chemistry is used as most analytical work is done in the liquid phase. [1] Wet chemistry is also known as bench chemistry, since many tests are performed at lab benches. [2]

  9. Stripping (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Stripping_(chemistry)

    Stripping is a physical separation process where one or more components are removed from a liquid stream by a vapor stream. [1] In industrial applications the liquid and vapor streams can have co-current or countercurrent flows.
