Patent number: 7438886Abstract: The present application relates to a process for removing hydrogen sulfide H2S from a gas (1) by contacting said gas with a liquid solution (2) containing ferric sulfate in an absorption column (RC). Ferric sulfate and H2S react at room temperature and at a pressure ranging from 1 to 1.2 atm. Ferric ions being reduced to two-valent iron and sulfide oxidised to elemental sulfur. The liquid (4) coming out of the absorption column is filtered in two steps, the retentate (6, 8) comprising elemental sulfur, the filtrate (5, 7) containing the iron ions. The filtrate is sent to a bioreactor (RB) for regeneration, i.e. oxidation of iron to Fe3+ by means of thiobacillus ferroxidans and air injection (10). The regenerated solution is reused in the absorption column (RC). The process faces the problems relating to the alignment between the chemical step and the biological step in order to obtain a process which can stably run continuously.Type: GrantFiled: December 4, 2003Date of Patent: October 21, 2008Assignee: Enitechnologie S.p.A.Inventors: Roberto Gianna, Umberto Barberini, Mario Galileo Valdiserri, Francesco Crescenzi, Andrea Robertiello

Patent number: 5660730Abstract: Process for the inertization of liquid waste, mud and solid waste, containing sulphates and heavy metals, which comprises a neutralization step of the compounds to be treated and an anaerobic reduction step of the sulphate ion to allow the formation of sulphide ions necessary for the process. A consortium of sulphate-reducing bacteria and lactobacilli is used, with whey as a carbon and nitrogen source.Type: GrantFiled: July 7, 1995Date of Patent: August 26, 1997Assignee: Eniricerche S.p.A.Inventors: Giuseppe Lucchese, Andrea Robertiello, Giuseppe Scolla

Patent number: 4976864Abstract: Process for the treatment of aqueous effluents from the production of epoxy resins, which effluents contain as their main impurities chlorohydrins, glycidol, isopropyl alcohol and sodium chloride, which process comprises the following steps:(a) hydrolytic treatment of the effluent under alkaline conditions, until the effluent's content of epichlorohydrin in reduced down to values of about 75 ppm, and the effluent's glycidol content is reduced to values lower than about 4,000 ppm;(b) removal of about 90% of sodium chloride from the hydrolyzed effluent; and(c) anaerobic digestion of the hydrolyzed, sodium chloride-deprived effluent, after preliminary dilution, neutralization and integration with nitrogen and phosphorus sources.The (b) step can be carried out by means of a process of concentration of the effluent, in order to cause sodium chloride to precipitate, or by submitting the same effluent to a treatment of electrodialysis.Type: GrantFiled: October 6, 1989Date of Patent: December 11, 1990Assignee: Eniricerche S.p.A.Inventors: Agostino Baradel, Gino Della Penna, Silvio Gulinelli, Mario Valdiserri, Andrea Robertiello

Patent number: 4087356Abstract: A method is disclosed, for depolluting fresh and sea waters from hydrocarbonaceous pollutants, the improvement consisting in that the usual microorganism cultures used for oxidizing the hydrocarbons are integrated by lipophilic and floating compounds which contain slow-release nitrogen in a form which can be assimilated by such micro-organisms. Ureidic derivatives of higher aldehydes are the preferred compounds. Inert supports can be used, if necessary, and still better results are achieved when using also nonionic dispersants and freeze-dried hydrocarbon-oxidizing microorganisms.Type: GrantFiled: November 4, 1976Date of Patent: May 2, 1978Assignee: Snamprogretti S.p.A.Inventors: Walter Marconi, Roberto Olivieri, Ludwig Degen, Andrea Robertiello
