| Abstract: | The purificatian technology, also named dust remover of spray water film with recovering acetic acid of low concentration at stage one and wet process to collect benzene hydrocarbon at stage two, is been raised to dispose the waste gas containing dust, acid, benzene together with its hydrocarbon while roasting tar residue of chromic oxide. The running results show that the rate of recovery of acetic acid is 95 %, and the rates of removal of benzene, methyl benzene and dimethyl benzene are 97.9%, 99.7%and 99.9% respectively. The exhaust gas conforms to the national emission standard. |
