  2. Carbonated water - Wikipedia

    en.wikipedia.org/wiki/Carbonated_water

    Higher gas pressure and lower temperature cause more gas to dissolve in the liquid. When the temperature is raised or the pressure is reduced (as happens when a container of carbonated water is opened), carbon dioxide effervesces, thereby escaping from the solution. The density of carbonated water is slightly greater than that of pure water.

  3. Carbonation - Wikipedia

    en.wikipedia.org/wiki/Carbonation

    Since carbonation is the process of giving compounds like carbonic acid (liq) from CO 2 (gas) {i.e. making liquid from gasses} thus the partial pressure of CO 2 has to decrease or the mole fraction of CO 2 in solution has to increase {P CO 2 /x CO 2 = K B} and both these two conditions support increase in carbonation.

  4. Carbonization - Wikipedia

    en.wikipedia.org/wiki/Carbonization

    The carbonization of wood in an industrial setting usually requires a temperature above 280 °C (536 °F), which frees up energy and hence this reaction is said to be exothermic. This carbonization, which can also be seen as a spontaneous breakdown of the wood, continues until only the carbonised residue called charcoal remains.

  5. Liquid carbon dioxide - Wikipedia

    en.wikipedia.org/wiki/Liquid_carbon_dioxide

    Liquid carbon dioxide is the liquid state of carbon dioxide (CO 2 ), which cannot occur under atmospheric pressure. It can only exist at a pressure above 5.1 atm (5.2 bar; 75 psi), under 31.1 °C (88.0 °F) (temperature of critical point ) and above −56.6 °C (−69.9 °F) (temperature of triple point ). [ 1 ]

  6. Dry ice - Wikipedia

    en.wikipedia.org/wiki/Dry_ice

    Subliming dry ice pellet, with white frost on the surface. Dry ice means the solid form of carbon dioxide.It is commonly used for temporary refrigeration as CO 2 does not have a liquid state at normal atmospheric pressure and sublimes directly from the solid state to the gas state.

  7. Hydrothermal carbonization - Wikipedia

    en.wikipedia.org/wiki/Hydrothermal_carbonization

    In addition, the resulting carbon mud can be made into briquettes and marketed as an environmentally friendly carbon dioxide-neutral "natural carbon" - Compared with the starting biomass, this can be dried by using deposition filtering or pressing with lower energy consumption and, due to its higher energy content per volume or mass, reduce ...

  8. Carbonatation - Wikipedia

    en.wikipedia.org/wiki/Carbonatation

    The carbonatation process is used in the production of sugar from sugar beets.It involves the introduction of limewater (milk of lime - calcium hydroxide suspension) and carbon dioxide enriched gas into the "raw juice" (the sugar rich liquid prepared from the diffusion stage of the process) to form calcium carbonate and precipitate impurities that are then removed.

  9. Solvay process - Wikipedia

    en.wikipedia.org/wiki/Solvay_process

    When properly designed and operated, a Solvay plant can reclaim almost all its ammonia, and consumes only small amounts of additional ammonia to make up for losses. The only major inputs to the Solvay process are salt, limestone and thermal energy, and its only major byproduct is calcium chloride, which is sometimes sold as road salt.
