    摘要： A novel liquid collector assembly has been developed for a reactor used in the sweetening of sour hydrocarbons (e.g. sour gasoline). This refinery process normally involves contacting a reaction liquid, comprising both aqueous (caustic solution) and organic (hydrocarbon) phases, with a fixed bed of oxidation catalyst. The collector assembly design, comprising a piping manifold and a plurality of dependent, vertically aligned, and perforated conduits, allows for improved separation of the reaction products into essentially pure treated hydrocarbon and spent alkaline reagent streams. If sodium hydroxide is used as caustic solution, for example, the treated hydrocarbon product will normally contain less than 1 ppm by weight of sodium.

    摘要： Sulfur dioxide and other sulfur compounds are removed from various waste gas streams including those from incineration, refinery sulfur processing, coal burning, or metal smelting operations. The process for sulfur compound removal comprises, in an adsorption vessel, the quenching and subsequent adsorption of the gas with a suitable adsorbent such as an aqueous basic solution (e.g. sodium hydroxide). Sulfur compounds are thus adsorbed into a liquid scrubbing solution predominantly in the form of partially oxidized species (i.e. sulfites, bisulfites, thiosulfites, sulfides, and bisulfides). In a separate heterogeneous catalytic oxidation step, these partially oxidized sulfur compounds are more completely oxidized so that the chemical oxygen demand of the effluent from the oxidation reactor is substantially reduced.
