Abstract

a presente invenção refere-se a processos e sistemas (10, 110) para produzir sulfato de potássio (36) como um subproduto de um processo de dessulfurização. dióxido de enxofre é absorvido (12) de um gás de combustão (14) utilizando uma solução contendo amônia para produzir uma solução de sulfato de amônio (24) que contém sulfato de amônio dissolvido. pelo menos uma primeira porção (25) da solução de sulfato de amônio (24) é aquecida (26) antes de dissolver cloreto de potássio (22) para formar uma lama (28) que contém cristais de sulfato de potássio (36) e uma solução de cloreto de amônia. a lama (28) é então resfriada (32) para precipitar cristais de sulfato de potássio (36) adicionais, então os cristais de sulfato de potássio (36) são removidos (34) para produzir uma solução de cloreto de amônia residual (38, 48) que contém cloreto de amônia dissolvido e sulfato de potássio dissolvido residual. a amônia (50) é então absorvida (40) dentro da solução de cloreto de amônia residual (38) para ainda precipitar cristais de sulfato de potássio (42), que são removidos (44) para produzir uma solução de cloreto de amônia residual (46) que é substancialmente livre de sulfato de potássio dissolvido.
