Abstract

Zgłoszenie dotyczy odzyskiwaniu metali, zwłaszcza wanadu, z popiołów lotnych, powstających w zakładach energetycznych podczas spalania ciężkich frakcji produktów ropopochodnych, szczególnie ciężkiego oleju opałowego czy pozostałości po destylacji ropy. Sposób według wynalazku polega na tym, że popiół lotny ze spalania ciężkich frakcji ropy naftowej, zalewa się wodą w stosunku 1:3 - 1:5 i w temperaturze od 15°C do 80°C, korzystnie 20°C do 40°C, miesza się do uzyskania silnie kwaśnego roztworu o pH poniżej 2, korzystnie 0,5 do 1,5, ewentualnie dodając roztworu kwasu siarkowego (VI) lub kwasu siarkowego (IV), po czym otrzymany roztwór oddziela się od nierozpuszczonego osadu w znany sposób, korzystnie za pomocą filtracji lub wirowania. Następnie z oczyszczonego roztworu wytrąca się związki wanadu poprzez dodanie wodnego roztworu silnego utleniacza, korzystnie 20% - 30% wodny roztwór nadtlenku wodoru, utrzymując mieszaninę w temperaturze 70°C do 90°C, korzystnie 80°C do 85°C przez 0,5 do 5 godzin, korzystnie 1 - 2 godzin. Z kolei z roztworu pozostałego po wytrąceniu wanadu, wytrąca się inne metale, tworzące nierozpuszczalne wodorotlenki, szczególnie nikiel, żelazo i glin, podnosząc za pomocą wodorotlenków alkalicznych pH roztworu do 9,0 – 11,0, korzystnie 10,5 i następnie po odfiltrowaniu osadów otrzymanych w warunkach alkalicznych, z otrzymanego przesączu, za pomocą rozpuszczalnych związków wapnia wytrąca się siarczany w postaci siarczanu wapnia, natomiast osad oddzielony z roztworu po ekstrakcji przedmiotowych spalin w pierwszym etapie przemywa się wodą, aż do uzyskania przewodności elektrolitycznej przesączu poniżej 1 mS, po czym następnie osad osusza się do stałej postaci.The application concerns the recovery of metals, especially vanadium, from fly ash generated in power plants during the combustion of heavy fractions of petroleum products, especially heavy fuel oil or oil distillation residues. The method according to the invention consists in pouring fly ash from the combustion of heavy crude oil fractions with water in a ratio of 1:3 - 1:5 and mixing at a temperature of 15°C to 80°C, preferably 20°C to 40°C. to obtain a strongly acidic solution with a pH below 2, preferably 0.5 to 1.5, optionally adding a solution of sulfuric acid (VI) or sulfuric acid (IV), and then the obtained solution is separated from the undissolved precipitate in a known manner, preferably using by filtration or centrifugation. Vanadium compounds are then precipitated from the purified solution by adding an aqueous solution of a strong oxidant, preferably 20% - 30% aqueous hydrogen peroxide, maintaining the mixture at a temperature of 70°C to 90°C, preferably 80°C to 85°C for 0.5 up to 5 hours, preferably 1 - 2 hours. In turn, from the solution remaining after the precipitation of vanadium, other metals are precipitated, forming insoluble hydroxides, especially nickel, iron and aluminum, raising the pH of the solution to 9.0 - 11.0, preferably 10.5, using alkali hydroxides, and then after filtering the precipitates obtained under alkaline conditions, sulphates are precipitated from the obtained filtrate using soluble calcium compounds in the form of calcium sulfate, while the precipitate separated from the solution after extraction of the exhaust gases in question is washed with water in the first stage until the electrolytic conductivity of the filtrate is below 1 mS, and then the precipitate is then dried to a solid form.
