    摘要: A process comprising creating an immiscible mixture by combining (a) a hydrocarbon feedstock containing contaminants and (b) a wash water, to create the immiscible mixture with at least three distinct layers: a hydrocarbon layer, a rag layer, and a brine layer. In this process a portion of the contaminants are removed from the hydrocarbon mixture where are then transferred to the brine layer. The brine layer is then separated from the immiscible mixture. In this process an alkalinity modifier is added in the process to reduce the emulsions in the immiscible mixture to create the at least three distinct layers.

    摘要: A treatment process for preparing a remediated liquid from a contaminated liquid originally containing more than 5 ppm hydrogen sulfide (H2S) and substantially without formation of precipitate, includes steps of steps of adding an aqueous solution containing at least one hydroxide compound at a collective concentration of 35-55 wt % to the contaminated liquid to achieve a concentration of 125-5000 ppm of the hydroxide compounds in the contaminated liquid, adding a fulvic acid and/or a humic acid to the contaminated liquid to achieve a concentration of 0.01-10 ppm of the acid(s) in the contaminated liquid, and dispersing the aqueous solution and the at least one organic acid in the contaminated liquid and allowing the aqueous solution and the at least one organic acid to react with the contaminated liquid for a period of time until a concentration of hydrogen sulfide in the contaminated liquid is reduced to ≤5 ppm.

    摘要: The present technology provides a method that includes contacting a composition with a caustic solution to produce a caustic-treated composition; combining the caustic-treated composition with silica particles to produce a slurry; and removing the silica particles from the slurry to produce a treated composition; wherein the composition includes one or more of animal fats, animal oils, plant fats, plant oils, vegetable fats, vegetable oils, greases, and used cooking oil and the composition includes: at least about 10 wppm of total metals, at least about 8 wppm of phosphorus, at least about 10 wppm of chlorine, at least about 10 wppm of sulfur, at least about 20 wppm of nitrogen, at least about 5 wt. % of free fatty acids; and has an acid number from about 10 mg KOH/g to about 150 mg KOH/g, and the silica particles has a particle size from about 10 microns to about 50 microns, a BET surface area from about 200 m2/g to about 1000 m2/g.
