    摘要: A treatment process for remediating; contaminants in a mixture of contaminated fluids, including at least one liquid fluid and at least one gaseous fluid, includes the steps of: preparing a treatment composition containing at least 80 volume % of an aqueous solution containing at least one hydroxide compound at a collective concentration of 35-55 weight percent, and at least one organic acid selected from the group consisting of fulvic acid and humic acid at a collective concentration of 0.1-5 wt % of the treatment composition; adding a dosage of the treatment composition to a mixture of contaminated fluids including a liquid portion and a gaseous portion; and allowing the treatment composition to react with the mixture of contaminated fluids for at least 10 minutes. A pH of the treatment composition is at least 12.0

    摘要: A treatment process for remediating a contaminated liquid containing more than 5 ppm hydrogen sulfide, includes steps of: preparing a treatment solution containing an aqueous solution containing ≥1 hydroxide compound, in which a collective concentration of the ≥1 hydroxide compound in the aqueous solution is in a range of 35-55 weight percent and the aqueous solution constitutes at least 95% of the treatment solution; adding to the liquid an amount of an treatment solution sufficient to reduce a concentration of hydrogen sulfide in the contaminated liquid to ≤5 ppm based on stoichiometry of reactions between the ≥1 hydroxide compound and the hydrogen sulfide in the liquid; and dispersing the treatment solution in the liquid and allowing the treatment solution to react with the contaminated liquid for a period of time until a concentration of hydrogen sulfide in the liquid is reduced to ≤5 ppm.

    摘要: A treatment method for remediating various contaminants including H2S, CO2, NH3 and other contaminants contained in fluids being extracted from the earth comprises steps of: preparing an aqueous based treatment composition containing water and collectively 35-55 weight percent of one or more hydroxide compounds; injecting a dosage amount of the treatment composition into contaminated fluids located in a subterranean deposit under the earth's surface such that the treatment composition mixes with the fluids deep under the earth's surface; and extracting a mixture of the contaminated fluids and the treatment composition through a well such that the treatment compositions remediates contaminants in the fluids as the mixture passes through the well to the earth's surface, wherein a dosage amount of the treatment composition may be 0.010 to 10.0 ml of the aqueous based treatment composition/liter of the contaminated fluids being extracted from the subterranean deposit.
