Abstract: The present invention describes a liquid-liquid extraction column with perforated plates and downpipes, having a majority of so-called “open” plates and a minority of so-called “closed” plates, the two types of plates differing in the degree of perforation. Application of the said column to the treatment of liquid-liquid systems with time-variable coalescence.

Abstract: A method for reducing the level of elemental sulfur from sulfur-containing hydrocarbon streams as well as reducing the level of total sulfur in such streams. Preferred hydrocarbon streams include fuel streams such as naphtha streams that are transported through a pipeline. The sulfur-containing hydrocarbon stream is contacted with a mixture of water, a caustic, a surfactant, at least one metal sulfide, and optionally an aromatic mercaptan. This results in an aqueous phase and a hydrocarbon phase containing reduced levels of both elemental sulfur and total sulfur.

Abstract: The present invention relates to a process for demetallating a petroleum stream by contacting a metals-containing petroleum feed in the presence of an aqueous base selected from Group IA and IIA hydroxides and carbonates and ammonium hydroxide and carbonate and mixtures thereof, an oxygen containing gas and a phase transfer agent at a temperature of up to 180.degree. C. for a time sufficient to produce a treated petroleum feed having a decreased metals content. The invention provides a method for enhancing the value of petroleum feeds that traditionally have limited use in refineries due to their metals, e.g., Ni and V content.

Abstract: In a method of removing acidic compounds, color, and polynuclear aromatic hydrocarbons, and for removing or converting hydrocarbons containing heteroatoms from used oil distillate, phase transfer catalysts are employed to facilitate the transfer of inorganic or organic bases to the substrate of the oil 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.

Abstract: A process for removing elemental sulfur from fluids such as refined petroleum products transported through pipelines normally used for the transport of sour hydrocarbon streams. The sulfur containing fluids are mixed with an immiscible aliphatic solution containing an inorganic caustic material, methanol or aqueous alcohol and an inorganic sulfide or hydrosulfide capable of reacting with the elemental sulfur in a mixing zone to form a polysulfide present in the immiscible alcoholic solution, passing the mixture of fluid and immiscible alcoholic solution to a phase separation zone wherein mixture separates into a fluid phase of reduced elemental and total sulfur content and an immiscible alcoholic phase containing polysulfides, recovering the fluid phase of reduced sulfur content from the phase separation zone, recovering the immiscible alcoholic phase containing polysulfide from the phase separation zone and recycling the immiscible alcoholic solution to the mixing zone. Alcohol from the spent immiscible alcoholic solution may be flash-distilled and recycled for reuse in the process.
