Ecological Systems and Devices Annotation << Back Research of ways of sulfide-alkaline neutralization drains on petrochemical manufactures Kudasheva F.H. Nowdays there is a problem of sulfide-alkaline drains (SAD) clearing from sulphurous connections. An opportunity of preliminary processing SAD hydrochloric (or the chamois) by an acid before full or partial removal меркаптидной sulfur as hydrogen sulphidewe was investigated. And also his further use in manufacture of a sulfuric acid, hydrosulfide of sodium and other kinds of production. Further processing SAD carried out oxidation by oxygen of air on heterogeneous catalysts. Application of an offered way of sulfide-alkaline neutralization drains allows to reduce the charge of air and the catalyst, and also to lower power consumption of process.
