Description
Przedmiotem wynalazku jest sposób usuwania siarkowodoru z gazów metoda Seaborda, przeznaczony dla kazdego gazu, w którym znajduje sie siarkowodór.Siarkowodór, bedac trucizna wielu katalizatorów, a w srodowiskach wodnych czynnikiem korodujacym, musi byc w procesach technologicznych usuwany. Stopien odsiarczania gazu ma decydujacy wplyw na zywot¬ nosc katalizatorów i trwalosc aparatury chemicznej oraz jest miernikiem jakosci metody odsiarczania. Dotych¬ czas proces odsiarczania gazów metoda Seaborda prowadzi sie w dwudzielnym aparacie, którego dolna czesc stanowi regenerator, a górna absorber. Absorbentem siarkowodoru, w metodzie Seaborda jest 3 — 5% wodny roztwór weglanu sodu. Ilosc siarkowodoru usunietego z gazu w tej metodzie wynosi 80- 90%.Celem wynalazku jest opracowanie sposobu, zapewniajacego wiekszy stopien o 'siarczania gazów.Istota wynalazku polega na tym, ze do gazu przed wprowadzeniem go do absorbera dodaje sie gazowy amoniak. Dosc amoniaku dodanego do gazu w stosunku molowym do siarkowodoru wynosi 0,2- 2. W wyniku wprowadzenia amoniaku do gazu stopien odsiarczania wzrasta i wynosi 95 - 99,5%.Przyklad.Do nieoczyszczonego gazu o skladzie: C02 - 7,5%; CO - 32,6%; CH4 - 04%; H2 - 32,3%; N2 - 32,2%; H2S - 0,3%, dodano gazowy amoniak w ta¬ kiej ilosci, ze stosunek molowy amoniaku do siarkowodoru wynosil 1,1 a nastepnie wprowadzono gaz do absor¬ bera. Uzyskano stopien odsiarczania gazu wynoszacy 99,5%.Zastrzezenie patentowe Sposób usuwania siarkowodoru z gazów metoda Seaborda, znamienny t y m, ze do gazu przed wprowadzeniem go do absorbera dodaje sie gazowy amoniak, przy czym stosunek molowy amoniaku do siar¬ kowodoru wynosi 0,2 — 2 PLThe subject of the invention is a method of removing hydrogen sulphide from gases by the Seabord method, intended for each gas containing hydrogen sulphide. Hydrogen sulphide, being a poison to many catalysts, and in water environments a corrosive factor, must be removed in technological processes. The degree of gas desulphurization has a decisive impact on the lifetime of the catalysts and the durability of the chemical equipment, and is a measure of the quality of the desulphurization method. Until now, the process of desulfurization of gases by the Seabord method is carried out in a two-part apparatus, the bottom part of which is a regenerator and the upper part is an absorber. The hydrogen sulphide absorber in the Seabord method is a 3-5% aqueous solution of sodium carbonate. The amount of hydrogen sulphide removed from the gas in this method is 80-90%. The object of the invention is to develop a method that provides a greater degree of gas sulphation. The essence of the invention is that gaseous ammonia is added to the gas before it is introduced into the absorber. The amount of ammonia added to the gas in molar ratio to hydrogen sulphide is 0.2-2. As a result of introducing ammonia into the gas, the desulphurization degree increases and amounts to 95 - 99.5%. Example. For crude gas composed of: CO 2 - 7.5%; CO - 32.6%; CH4 - 04%; H2 - 32.3%; N2 - 32.2%; H 2 S - 0.3%, gaseous ammonia was added in such an amount that the molar ratio of ammonia to hydrogen sulfide was 1.1, and then the gas was introduced into the absorber. The degree of desulphurization of the gas was obtained at 99.5%. Patent claim A method of removing hydrogen sulphide from gases by the Seabord method, characterized in that, before introducing it into the absorber, gaseous ammonia is added to the gas, the molar ratio of ammonia to hydrogen sulphide being 0.2 - 2 PL
