1980/7/1· The carbon dioxide produced in stage (vi) is conveniently used for the carbonation of the "brine mud" in stage (i). A range of aqueous solutions of sulphuric acid containing up to 98 percent by weight of H 2 SO 4 may be used, and also fuming sulphuric acid or oleum, but it is preferred to use sulphuric acid solutions containing from 40% to 98% by weight of H 2 SO 4 .
Food preservation - Wikipedia
However, carbon dioxide has an advantage in this respect, as it kills organisms through hypercarbia and hypoxia (depending on concentration), but it requires concentrations of above 35%, or so. This makes carbon dioxide preferable for fumigation in situations where a hermetic seal cannot be maintained.

The project planned to use a technology that applies a supercritical carbon dioxide (sc-CO2) in the extrusion phase of the plastic recycling process. This process was expected to partially, or totally, serve as a substitute for two of the three stages involved in conventional treatments, which should reduce the labour requirement and the consumption of energy and water.

Freeze-drying is an extreme form of vacuum drying in which the water or other solvent is frozen and drying takes place by sub the solid phase. Freeze-drying is extensively used in two situations: (1) when high rates of decomposition occur during normal drying; and (2) with substances that can be dried at higher temperatures, and that are thereby changed in some way.

1986/8/15· Nitrogen was found to elute CO2 from the drying agents at about the same rate as it had been adsorbed. It is concluded that awareness of these adsorption/elution phenomena by drying agents should prevent errors from being made in the calibration of CO2 analysers, in the analysis of CO2, and in the measurement of specific activity or isotopic enrichment of CO2.
