Abstract: A method for the removal of sulfur and nitrogen containing compounds from petroleum distillates. Sulfur- and nitrogen-containing compounds are oxidized using a selective oxidant to create compounds that can be preferentially extracted from a petroleum distillate due to their increased relative polarity. Oxidation is accomplished by contacting an oxidant with a distillate under optimum conditions for that distillate and continuing the reaction until oxidized sulfur- and nitrogen-containing compounds are confirmed. Extraction is accomplished by contacting oxidized distillate with a non-miscible solvent that is selective for the relatively polar oxidized sulfur- and nitrogen-containing compounds. The oxidized compounds and solvent are separated from the distillate by gravity separation or centrifugation. The distillate is water washed and polished using clay filtration. The extraction solvent is separated from the solvent/oxidized compound mixture by a simple distillation for recycling. The high sulfur/high nitrogen fraction can be recovered using any number of treatments.

Abstract: A system and/or process for decreasing the level of at least one organic fluoride present in a hydrocarbon mixture by first passing the hydrocarbon mixture to an eductor and educting into the hydrocarbon mixture a catalyst comprising a volatility reducing additive and hydrofluoric acid to produce a hydrocarbon-catalyst mixture, permitting the hydrocarbon-catalyst mixture to undergo a phase separation to produce a hydrocarbon phase having a lower concentration of at least one organic fluoride than the hydrocarbon mixture and to produce a catalyst phase, and withdrawing at least a portion of the hydrocarbon phase to thereby form a hydrocarbon product stream, are disclosed. In an alternative embodiment, a system and/or process for controlling the concentration of at least one organic fluoride and/or the RON of the hydrocarbon mixture by adjusting the amount of volatility reducing additive present in the catalyst are disclosed.

Abstract: A metal salt removal procedure for use with a crude oil flow is disclosed. A small amount of water, and a caustic in the range of 7-12 pH, and preferably 9-12 pH, are injected to form water bubbles surrounded by oil. An ethylene oxide reacted with polypropylene glycol at 350° F. or so yields a water soluble demulsifier added at the rate of a few ppm to the water in oil mix. The added reaction product, a polyol, enables metal salt isolation in the water.
