A process for recovering nitric acid or salts thereof, comprising: contacting, in the presence of water, an water-immiscible ionic liquid of the formula [A][X], wherein [A] represents a phosphonium or ammonium cation and [X] represents a counter anion which is NO, an halide anion displaceable by NO, or both, with a fluid which contains HNOand at least one more mineral acid, or precursors of said acids, and partition, under mixing, said acids between aqueous and organic phases and form nitrate-loaded ionic liquid of the formula [A][NO]where Z indicates a molar amount of nitrate held in the ionic liquid beyond the positions occupied by the nitrate counter ions; separating the so-formed mixture into an organic phase comprising a nitrate-loaded ionic liquid of the formula [A][NO]and an aqueous phase consisting of a nitrate-depleted aqueous solution that contains the other mineral acid(s); stripping the nitric acid from said nitrate-loaded ionic liquid to create an aqueous nitrate solution and regenerate ionic liquid of the formula [A][NO]with reduced nitrate loading, or unloaded [A][NO]ionic liquid.

Separation and concentration of nitrate from aqueous solutions and gaseous streams

Provided herein a process for purification of an ionic liquid from heavy metals, comprising combining heavy metal-containing ionic liquid and a sulfide source to form heavy metal sulfide, and separating said heavy metal sulfide from the ionic liquid.

Process for separation of heavy metals and/or sulfur species from ionic liquids

A process for removing impurities from a flue gas, comprising treating the flue gas with a liquid absorbent comprising (i) a precursor of chlorine dioxide and (ii) an organic ionic liquid, and releasing a purified flue gas into the atmosphere. The process is useful for removing Hg, SOand NOx.

Process for removing pollutants from a flue gas

Process for treating a medium by the removal or destruction of one or more undesired substances present in said medium, comprising combining hydrogen peroxide and alkali hydroxide in an aqueous solution to form superoxide, and bringing the resultant superoxide-containing solution into contact with said medium. The process is useful for the destruction of halogenated organic pollutants and also for carbon dioxide removal from flue gases. The process can also be applied for soil remediation.

Preparation of an aqueous reagent for the absorption or destruction of pollutants

The invention is a process for absorbing sulfur dioxide from a gaseous stream with the aid of an ionic liquid, followed by the release of sulfur dioxide from the ionic liquid on addition of a polar solvent and the regeneration of the ionic liquid.

Process for controlling the emission of flue gases

Provided is a process for controlling heavy metal (e.g., mercury) emission in SO-containing flue gas, comprising passing a stream of the flue gas () through a wet scrubber () where it is brought into contact with a liquid absorbent () comprising an ionic liquid, an oxidizer () and polar protic organic solvent, wherein the amount of said organic solvent is adjusted such that the SOabsorption is minimized while operating said wet scrubber at a temperature lower than the normal working temperature that would be used in the absence of said solvent. The process may be preceded by an initial stage where a fluoride-containing liquid is used for reducing the amount of sulfur dioxide in the flue gas stream; the sulfur dioxide can be subsequently desorbed from the fluoride-containing liquid upon the addition of a polar solvent.

A wet scrubber for absorbing elemental heavy metal from a gas stream, a liquor for a wet scrubber, and a power-plant comprising a wet scrubber are described. The wet scrubber includes a vessel having a gas inlet and outlet. In the vessel is a liquor including a oxidizer capable of oxidizing the elemental heavy metal and an ionic liquid. The liquor is substantially free of any ligand capable of bonding an ion of the heavy metal.
