  • Redox gas sweetening solutions
    Patent number: 8628743
    Abstract: Gas sweetening solutions are described that are capable of removing hydrogen sulfide from gas streams. These gas sweetening solutions increase the size of produced sulfur particles and thereby improve efficiency of their separation, while simultaneously reducing corrosive effects of the sweetening solutions. The gas sweetening solutions comprise at least one chelating agent, cationic iron and a mixture of nitrite salt and phosphate species.
    Type: Grant
    Filed: March 17, 2009
    Date of Patent: January 14, 2014
    Assignee: Research Institute of Petroleum Industry (RIPI)
    Inventors: Masih Hosseini Jenab, Jaber Neshati, Khaled Forsat
  • Catalytic composition for oxidation of hydrogen sulfide, and methods for preparation thereof
    Patent number: 7704911
    Abstract: The present invention provides a catalytic composition for use in an oxidation-reduction process for effecting the catalytic oxidation of hydrogen sulfide in gas strains comprising a water soluble iron compound, a mixture of two chelating agents, comprising Na2EDTA and Na4EDTA, and at least one stabilizer.
