Carbon dioxide is also removed and to ensure that an appropriate amount of carbon dioxide remains, a mixture of nitrogen and carbon dioxide may be used for the sparging gas. [ 3 ] Purging and blanketing: The removal of oxygen from the headspace above the wine in a container by flushing with a similar gas mixture to that used for sparging is ...
A gas regulator attached to a nitrogen cylinder. Industrial gases are the gaseous materials that are manufactured for use in industry.The principal gases provided are nitrogen, oxygen, carbon dioxide, argon, hydrogen, helium and acetylene, although many other gases and mixtures are also available in gas cylinders.
Carbon dioxide phase diagram. Supercritical carbon dioxide blend (sCO 2 blend) is an homogeneous mixture of CO 2 with one or more fluids (dopant fluid) where it is held at or above its critical temperature and critical pressure. [1]

Carbon dioxide is a by-product of the fermentation of sugar in the brewing of beer, whisky and other alcoholic beverages and in the production of bioethanol. Yeast metabolizes sugar to produce CO 2 and ethanol, also known as alcohol, as follows: C 6 H 12 O 6 → 2 CO 2 + 2 CH 3 CH 2 OH
A natural-gas processing plant in Aderklaa, Austria. Natural-gas processing is a range of industrial processes designed to purify raw natural gas by removing contaminants such as solids, water, carbon dioxide (CO 2), hydrogen sulfide (H 2 S), mercury and higher molecular mass hydrocarbons to produce pipeline quality dry natural gas [1] for pipeline distribution and final use.

Supercritical fluid chromatography (SFC) [1] is a form of normal phase chromatography that uses a supercritical fluid such as carbon dioxide as the mobile phase. [2] [3] It is used for the analysis and purification of low to moderate molecular weight, thermally labile molecules and can also be used for the separation of chiral compounds.
Landfill gas is a mix of different gases created by the action of microorganisms within a landfill as they decompose organic waste, including for example, food waste and paper waste. Landfill gas is approximately forty to sixty percent methane, with the remainder being mostly carbon dioxide.
