| titleOfInvention | Method for desulphurization of battery paste |
| abstract | Method for desulphurization of battery paste using a circulating aqueous solution of polyamines, where the pulp desulfurization stage is carried out in an aqueous solution of a defined amine and where said solution is saturated with carbon dioxide resulting in a solid product, which it is filtered off, and the solution is regenerated and the regenerated amine solution is incorporated back into the process, characterized in that the circulating solution of the polyamine or a mixture of polyamines is saturated with carbon dioxide to eliminate the calcium residues from the solution and then filtered to isolate the precipitated calcium carbonate, preferably using pressure filtration, the battery paste is subsequently leached with the thus obtained circulating aqueous solution of the polyamine or a mixture of polyamines followed by filtration of the suspension obtained, preferably using filtration pressurized and washed in the filter to obtain r a desulfurized paste of low sulfur content and circulating solution, said solution being regenerated by removing the lead and carbon dioxide residues therefrom by the action of sulfuric acid and then filtering it to separate the lead sulfate and recirculating it to the basic procedure, while that the circulating amine solution obtained containing sulfate ions is regenerated with calcium hydroxide in a crystallizer to obtain a gypsum suspension, which is preferably separated by pressure filtration and washed in the filter to produce gypsum and circulating solution, the concentration being adjusted of the polyamine or polyamine mixture in the solution by mixing a new portion of the polyamine or polyamine mixture and returning the adjusted solution at the beginning of the procedure. |
