An ethylene oxide (EtO) scrubbing sheet for the removing fugitive EtO emissions from, for example, sterilized medical devices and leaks from chemical plants. The scrubbing sheet comprises an acid impregnated layer, a second layer impregnated with an acid neutralizer, combined inside a gas porous protective membrane. The EtO enters the sheet by diffusion and is removed by irreversible chemical reaction.

The application of geocatalysts in controlling CO.sub.2 capture processes in situ as well as in a reaction vessel, chamber or tower is described. More specifically, a process for controlling the reaction of a CO.sub.2-containing gas stream with one or more starting materials selected from waste building material, mineral, rock, sand, amorphous material or combinations thereof is disclosed: wherein said starting material comprises Si and/or Al, and one or more divalent cation(s), water, and one or more organic compound(s) to control the reaction: thereby providing a product comprising: at least one carbonate mineral and preferably colloidal silica.

A process, composition, and apparatus for carbon dioxide (CO.sub.2) conversion are disclosed. The CO.sub.2 conversion comprises reacting CO.sub.2 with a cyclopropenimine (CPI) to activate the CO.sub.2 and transferring the activated CO.sub.2 to generate a product of the transferring. The transferring also generates a conjugate acid of the CPI. The process further comprises regenerating the CPI from the conjugate acid.

Systems for abatement of sterilizing gas are disclosed. An example system may include a medical device package having a medical device disposed therein. A sterilizing gas abatement member may be disposed adjacent to the medical device. The sterilizing gas abatement member may be configured to abate a sterilizing gas present adjacent to the medical device.

The present invention relates to a plant and method for the purification of fumes from industrial discharges and/or for the recovery and reconversion of sulfur oxides and/or nitrogen oxides and/or carbon dioxide contained in said fumes. Said method comprises the passage into one or more aqueous solutions, where said aqueous solutions are selected from the group comprising: solution with an acid pH, between 0.5-1; solution at a pH between 3 and 5, at about pH 4; Ca(OH).sub.2 or CaCl.sub.2 or calcium acetate solution; solution at a pH between 8 and 9.

The present invention relates to a device for absorbing water using a liquid desiccant and the regeneration of said liquid desiccant by evaporating the absorbed water. The device may further be used in an air cooler. The invention also relates to a method for controlling a device for absorbing water.

Slurries and methods of making slurries for modifying and extending relative humidity control ranges. The slurries may include a saturated aqueous salt and one or more other reagents selected to provide a controlled modifiable narrow range of relative humidity. The saturated aqueous salt may be one or more of sodium chloride, potassium chloride, potassium citrate, sodium formate, and/or magnesium chloride, and the one or more other reagents may be one or more of a lactate salt, glycerol, and/or an acetate salt, for example.

A method for simultaneously removing high-load sulfur dioxide and nitrogen oxide in waste gas, relating to the technical field of industrial waste gas purification by biological methods. According to the method, the waste gas is led into a simultaneous desulfurization and denitrification packing tower and removed, microbial floras for simultaneously removing the sulfur dioxide and the nitrogen oxide are loaded on fillers of the packing tower, and the molar concentration ratio of the sulfur dioxide to the nitrogen oxide in the waste gas is (0.761.06):1.

The present invention provides a process for the production of an organic acid from an aqueous medium of a monovalent salt of an organic acid using bipolar electrodialysis via a two compartment electrodialysis unit.
