Hydrocarbons free from deposits or embedments and chemical composition and methods for remediation of hydrogen sulfide and other contaminants

摘要

A treatment process for remediation of contaminated liquid containing more than 5 ppm hydrogen sulfide and essentially no sediment formation, including the process of adding an aqueous solution containing at least one hydrogen oxide compound to the collective concentration of the contaminated liquid by weight of 35% to 55%, so as to: When the concentration of hydrogen oxide compound in the polluted liquid reaches 125-5000 ppm, at least one organic acid is added to the liquid to make the concentration in the polluted liquid reach 0.01-10 ppm,And the aqueous solution and organic acid are dispersed in the polluted liquid, and the aqueous solution and organic acid are allowed to react with the polluted liquid for a period of time, until the concentration of hydrogen sulfide in the polluted liquid is reduced to ≤ 5 ppm.
