摘要： The present invention provides an apparatus and process for generating a reagent solution of sulfur trioxide in a carrier. The apparatus includes a reagent generator which has associated therewith means for introducing sulfur trioxide from a source into the reagent generator, means for introducing a carrier such as a liquid halocarbon or a gas which is nonreactive with the sulfur trioxide into the reagent generator, and means for introducing oleum into the reagent generator. The sulfur trioxide, carrier and oleum are contacted in the reagent generator to provide a reagent solution of sulfur trioxide in the carrier. Additionally, the apparatus includes means for removing oleum from the reagent generator, as well as means for removing the reagent solution from the reagent generator. In a preferred embodiment, the apparatus for generating the reagent solution also includes, in conjunction with the reagent generator, a treatment chamber for the surface treatment of polymeric resinous material including medical products which have polymeric resinous material on exposed surfaces thereof.

摘要： For adjusting the concentration of acids or lyes, in particular of sulfuric acid, the acid or lye is supplied through an inlet to a mixing chamber, is mixed therein with a medium for adjusting the concentration, and the concentration-adjusted acid or lye is discharged from the mixing chamber through an outlet. To achieve a uniform dilution of the acid or lye and small concentration deviations with low pressure loss, the medium for adjusting the concentration, in particular water, is charged to the acid or lye before the inlet to the mixing chamber and the acid stream or lye stream and the stream of the medium subsequently are deflected preferably by 90°.

摘要： The present invention provides a system for recycling spent sulfuric acid, which aims at providing an industrially advantageous system featuring that spent sulfuric acid is effectively utilized at a place other than a discharge source regardless of geographical conditions, and also provides a method for recycling waste sulfuric acid, and recycled sulfuric acid. In the system, when spent sulfuric acid discharged or collected at a discharge source A is transported by a carrier unit B, and used at a user office C, a concentration of the spent sulfuric acid is measured and/or adjusted at least at one of the discharge source A, the carrier unit B, and the user office C. The spent sulfuric acid waste liquid discharged or collected at the discharge source A is reutilized by being mixed with at least one of a hydrogen peroxide solution and water.

摘要： Sulfur is burned in oxygen at high temperatures and high pressures without the use of a catalyst. The product gas, i.e., SO 3 , SO 2 and O2, is condensed to separate part of the SO 2 and O 2 and then distilled to separate the remainder and produce S0 3 and/or oleum and sulfuric acid. The SO 2 and O 2 from the separator (3) and still (4) are recycled to the burner (1).
