ZAŠTITA OD KOROZIJE ČELIČNE KONSTRUKCIJE LO-CAT POSTROJENJA ZA DESULFURIZACIJU CO2 NA CPS MOLVE |
THE CORROSION PROTECTION OF STEEL CONSTRUCTION IN LO-CAT PLANT FOR DESULPHURING CO2 ON CPS MOLVE |
|
|
SAŽETAK U radu je opisana zaštita čelične konstrukcije od korozije Lo-Cat postrojenja za desulfurizaciju CO2. U toku rada postrojenja, zbog izrazito korozionih uvjeta nastupilo je oštećenje postojećeg zaštitnog premaza. Postupak obnove zaštite proveden je predobradom čelične konstrukcije s vodenim mlazom pod tlakom 500 bar i primjenom tri sloja premaza Hempadur 4515. KLJUČNE RIJEČI: Lo-Cat postrojenje, zaštitni premaz, korozija čelične konstrukcije, desulfurizacija, metoda vodenog mlaza |
ABSTRACT In this paper the protection of steel construction against corrosion in Lo-Cat plant for desulphuring CO2 was described. During the exploitation of plant, because of very strong corrosion conditions, the existing protection coating system was damaged. The renewal of the protection coating system, surface preparation by high pressure water jet 500 bar and application of three coating layers of Hempadur 4515 were performed. KEY WORDS: Lo-Cat plant, protective coating, steel structure corrosion, desulphuring, water jet |
