  • Publication number: 20140339468
    Abstract: A method for separating arsenic and heavy metals in an acidic washing solution which contains both arsenic and heavy metal, more particularly in a washing solution which is formed in copper smelting and contains sulphuric acid, comprises a separation process section, in which arsenic and at least one primary heavy metal are separated from one another. The separation process section comprises a processing step, in which hydrogen peroxide H2O2 is added to the washing solution, and the separation process section comprises a precipitation stage, in which the washing solution is admixed with a sulphide precipitation reagent, causing the at least one primary heavy metal to precipitate in the form of a metal sulphide. The processing step in this system is carried out before the precipitation stage.

  • Publication number: 20140190870
    Abstract: The use of a composition including a transition metal salt and at least one water-soluble aldehyde or water-soluble aldehyde precursor scavenges H2S that is present in aqueous fluids (e.g. produced water liquid streams), natural gas and in oil and mixtures thereof (e.g. mixed production streams that contain all three phases) better than either component when used alone. The resulting scavenger combination significantly increases the reaction rate and the overall scavenging efficiency, i.e. capacity over the case where each component is used alone, in the same total amount. Non-limiting examples of the metal salt include zinc or iron carboxylates, and a non-limiting example of a water-soluble aldehyde or water-soluble aldehyde precursor is ethylene glycol hemiformal.
