摘要: Hydrogen sulfide (H2S) and/or mercaptan scavengers are chemicals that remove H2S and/or mercaptans from gas, oil and water. Water-based formulations may be made and used employing scavenging compounds having the formulae: wherein each R1, R2, R3, and R4 are the same or different and are selected from the group consisting of hydrogen, an alkyl, an alkenyl, an aryl, an acyl, a halogen, a hydroxyl, a nitro, an alkyl ester, an aryl ester, an alkyl ether, an aryl ether, a hydroxymethyl, an anhydride group, an amino, and a sulfide. In one non-limiting embodiment the compounds (A) and (B) do not contain nitrogen atoms. Water-based formulations, such as those using a protic solvent with the above compounds, work well as H2S scavengers.

摘要: The invention relates to a method for desulfurizing naphtha boiling-range hydrocarbons such as cracked naphtha. More particularly, the invention relates to hydrotreating the naphtha under selective hydrotreating conditions, and then removing mercaptans from the hydrotreater effluent using a caustic extractant.

摘要: In a method of removing acidic compounds, color, and polynuclear aromatic hydrocarbons, and for removing or converting hydrocarbons containing heteroatoms from petroleum distillates, phase transfer catalyst is employed to facilitate the transfer of inorganic or organic bases to the substrate of the distillate. An inorganic or organic base, a phase transfer catalyst selected from the group including quaternary ammonium salts, polyol ethers and crown ethers, and used oil distillate are mixed and heated. Thereafter, contaminants are removed from the used oil distillate through distillation. A solvent is then mixed with the resulting distillate to extract contaminants therefrom. The solvent is recovered and distilled to separate the contaminants therefrom, and is then reused. The petroleum distillate having the contaminants separated therefrom is also distilled to remove any remaining solvent therefrom, with the recovered solvent being reused.
