Diagnostics of corrosion damage to technological equipment at OAO Voronezhsintezkauchuk

A diagnostics of the causes of a corrosion attack on heat-exchange equipmen t (the structural material-CRO) in the medium of an water-alcohol absorbent for divinyl at the Voronezhsintezkauchuk plant was performed in terms of a systematic approach with the use of a complex of physical-chemical methods . A reasonable approach to its protection, implying the alkalization of the absorbent to pH 10-11 and the replacement of pipeline sections most attack ed by erosion-corrosion with those made of fluoroplastic or glass ceramic i s recommended.
