A method of making an aqueous mixture of ozone and water comprising pumping a solution of ozonated water through a high cavitation rate homogenizing device, thereby causing formation of gas phase nanobubbles of ozone in the solution. The high cavitation rate homogenizing device may be a homogenizing mixer. The high cavitation rate homogenizing device may be comprised of rotors and stators moving in close proximity relative to each other and separated by the solution of ozonated water. The relative motion of the rotors and stators may cause up to 500 million cavitation events per second in the solution of ozonated water, thereby causing the formation of gas phase nanobubbles of ozone. A computer-implemented method of treating waste water from a source is also disclosed. The method may include making the aqueous mixture of ozone and water.

Provided is an exhaust gas processing system which has excellent durability, allows reducing processing costs, has good desulfurization and denitration efficiency, and can efficiently recover carbon dioxide
with high purity. This exhaust gas processing system has: a desulfurization unit which removes sulfur oxides from the exhaust gas by the limestone-gypsum method, a denitration unit which is arranged downstream of the desulfurization unit and removes nitrogen oxides from the exhaust gas; a carbon dioxide recovery
unit which is arranged downstream of the denitration unit and recovers carbon dioxide
from the exhaust gas; and an oxygen supply unit which supplies the desulfurization unit with part of the recovered
gas discharged from the carbon dioxide recovery
unit as the oxygen source. An analysis device is used to monitor the purity and recovery
rate of the carbon dioxide recovered
by the carbon dioxide recovery
unit, and on the basis of said purity and recovery
rate, the ratio of recovered
gas supplied to the desulfurization unit is adjusted.

||PCT/CA2014/050897||QUEEN'S UNIVERSITY AT KINGSTON||BONIFACE, Kyle J.|
The present application provides a composite material that comprises a solid and solid-supported non-polymeric switchable moiety, wherein the switchable moiety comprises a functional group that is switchable between a first form and a second form, said first form being neutral and hydrophobic, and said second form being ionized and hydrophilic. The composite material converts to, or is maintained in, said second form when the switchable moiety is exposed to CO2
at amounts sufficient to maintain the ionized form. The composite material converts to, or is maintained in, said first form when CO2
is removed or reduced to an amount insufficient to maintain the ionized form. CO2
is removed or reduced by exposing the composite material to heat and/or a flushing inert gas such as N2, Ar, or air. Envisioned uses of these composite materials includes removing water from non-aqueous solvents, removing water vapour from gaseous mixtures, and cleaning industrial reaction vessels and/or pipelines.
