摘要： This invention relates to a process for sweetening a sour hydrocarbon fraction containing mercaptans. The process involves contacting the hydrocarbon fraction in the presence of an oxidizing agent with a catalytic composite, ammonium hydroxide and a quaternary ammonium hydroxide. There is a synergistic effect between the ammonium hydroxide and the quaternary ammonium hydroxide. Use of ammonium hydroxide instead of an alkaline hydroxide allows the waste stream to be re-used in other parts of the refinery, and allows for easier disposal of the waste stream.

摘要： Although high naphthenic acid hydrocarbon feedstocks normally need to be washed with caustic prior to being sweetened in a fixed bed mercaptan-to-disulfide oxidation process to avoid bed plugging, the prewash can be eliminated if aqueous ammonia is used concurrent with and as a part of the sweetening process. Aqueous ammonia injected into a sour hydrocarbon stream prior to the sweetening zone not only eliminates bed plugging, but affords an aqueous phase from which naphthenic acids may be recovered easily and economically. The ammonia also can be recovered for reuse, affording a process with considerably enhanced economic return.

摘要： A liquid-liquid contacting apparatus is disclosed. The apparatus is useful in extracting mercaptans from a hydrocarbon stream such as cracked gasoline by nonturbulent countercurrent contacting of the hydrocarbon stream with an aqueous caustic solution. The denser liquid phase flows downward from an upper phase separation zone through a connecting cylindrical contacting zone into a lower phase separation zone. Liquid withdrawal and addition means communicate with each separation zone. A mass of fibrous contacting strands is suspended in the contacting zone. The contacting strands are preferentially wetted by either of the two liquid phases to provide a large surface area which enhances extraction capacity.

摘要： A process is disclosed for treating hydrocarbon streams such as naphtha by the oxidation of mercaptans into disulfide compounds which remain in the hydrocarbon stream. The conversion is effected during passage of the hydrocarbon and an aqueous stream downward through a cylindrical mass of liquid-liquid contact material. The liquids then flow through a cylindrical screen into an annular separation zone which surrounds a lower part of the contact material. After decantation in the separation zone, the aqueous material, which preferably contains the oxidation catalyst, is recycled.

摘要： An improved process is disclosed for the removal of nitrogen compounds from light hydrocarbon streams. Such nitrogen removal enhances the performance of catalytic processes which upgrade light hydrocarbons, especially light olefins, such as isomerization and etherification. The nitrogen-removal process can usefully be combined with steps for removal of sulfur compounds and highly unsaturated compounds in a process combination for upgrading the light hydrocarbons.
