Analysis and evaluation of the biogas purification technologies from H2S
Mokslas: Lietuvos Ateitis, 2023 H2S concentrations in biogas are limited by environmental regulations. Because these gases are toxic to human health, cause corrosion, and damage the combined heat and power (CHP) engines and other metallic parts after burning.

The impact of road maintenance substances on metals surface corrosion
Mokslas: Lietuvos Ateitis, 2011 The purpose of research is to assess changes in the visual metal surface due to the exposure of road maintenance salts and molasses (‘Safecote’). Chlorides of deicing salts (NaCl, CaCl2) are the main agents affecting soil and water resources as well as ...

MIKROBIOLOŠKI POTICANA KOROZIJA ODVODNIH CIJEVI
25. Međunarodno savjetovanje o zaštiti materijala i industrijskom finišu "KORMAT 2022" : zbornik radova, 2022 Nepoželjno trošenje metala uslijed štetnog djelovanja metaboličkih reakcija mikroorganizama naziva se mikrobiološki poticana korozija (MIC). Ova vrsta korozije najviše zahvaća odvodni sustav, naftnu industriju i brodogradnju. Anaerobne i aerobne bakterije koje su prisutne u vodenom okruženju i tlu narušavaju strukturu metalne površine odvodnih cijevi ...

Tehnički glasnik, 2011 Napetosna korozija je vrlo neugodan lokalni korozijski proces koji do danas u cijelosti nije obrađen i razjašnjen. Radi se o korozijskom fenomenu koji najčešće vrlo lagano interkristalno ili transkristalno razara strukturu materijala i nerijetko iznenada dovodi postrojenja izvan upotrebe.
