  2. Visbreaker - Wikipedia

    en.wikipedia.org/wiki/Visbreaker

    A schematic diagram of a Visbreaker unit. The term coil (or furnace) visbreaking is applied to units where the cracking process occurs in the furnace tubes (or "coils")."). Material exiting the furnace is quenched to halt the cracking reactions: frequently this is achieved by heat exchange with the virgin material being fed to the furnace, which in turn is a good energy efficiency step, but ...

  3. Breaker bar - Wikipedia

    en.wikipedia.org/wiki/Breaker_bar

    Breaker bar. A breaker bar (also known as a power bar) is a long non-ratcheting bar that is used with socket wrench-style sockets.They are used to break loose very tight fasteners because their additional length allows the same amount of force to generate significantly more torque than a standard length socket wrench.

  4. Cracking (chemistry) - Wikipedia

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

    In petrochemistry, petroleum geology and organic chemistry, cracking is the process whereby complex organic molecules such as kerogens or long-chain hydrocarbons are broken down into simpler molecules such as light hydrocarbons, by the breaking of carbon–carbon bonds in the precursors.

  5. Periodic table - Wikipedia

    en.wikipedia.org/wiki/Periodic_table

    The periodic table, also known as the periodic table of the elements, is an ordered arrangement of the chemical elements into rows ("periods") and columns ("groups"). It is an icon of chemistry and is widely used in physics and other sciences.

  6. Separatory funnel - Wikipedia

    en.wikipedia.org/wiki/Separatory_funnel

    Typical sizes are between 30 mL and 3 L. In industrial chemistry they can be much larger and for much larger volumes centrifuges are used. The sloping sides are designed to facilitate the identification of the layers. The tap-controlled outlet is designed to drain the liquid out of the funnel.

  7. Tyndall's bar breaker - Wikipedia

    en.wikipedia.org/wiki/Tyndall's_bar_breaker

    The bar breaker experiment comprises a very rigid frame (d) and a massive connecting rod (b). The rod is held on one side by a cast iron bar (c) that is going to be broken in the experiment and, at the other end, by a nut (a) that is used to compensate the thermal expansion. [3]

  9. Beer–Lambert law - Wikipedia

    en.wikipedia.org/wiki/Beer–Lambert_law

    The Beer–Bouguer–Lambert (BBL) extinction law is an empirical relationship describing the attenuation in intensity of a radiation beam passing through a macroscopically homogenous medium with which it interacts.
