A Method for purifying gas loaded with dust particles of various sizes, which method includes the following steps: (a) the gas loaded with dust particles is subjected to wet gas scrubbing at or above the dew point, during which operation any acid gaseous components present in the gas are absorbed and the major proportion of coarse dust particles having a size of .gtoreq.50 .mu.m is removed by a scrubbing liquid, after which (b) the remaining dust particles present in the gas are collected at or above the dew point in an installation for removing dust from gas, purified gas being obtained.

Um método para purifying o gás carregou com as partículas de poeira dos vários tamanhos, que o método inclui as seguintes etapas: (a) o gás carregado com as partículas de poeira são sujeitados a esfregar de gás molhado em ou acima do ponto de orvalho, durante que a operação todos os componentes gasosos ácidos atuais no gás são absorvidos e a proporção principal das partículas de poeira grosseiras que têm um tamanho do mu.m do gtoreq.50 é removida por um líquido esfregando, depois do qual (b) as partículas de poeira restantes atuais no gás são coletados ou acima do ponto de orvalho em uma instalação para remover a poeira do gás, gás purified que está sendo obtido.
