Analysis and evaluation of the biogas purification technologies from H2S

open access: yesMokslas: 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

open access: yesMokslas: 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 ...

The contribution of condensation-corrosion in the morphological evolution of caves in semi-arid regions: preliminary investigations in the Kyrenia Range, Cyprus

open access: yesActa Carsologica, 2019
The condensation-corrosion process occurs when airflow cools at the contact with colder cave walls. Condensed water becomes aggressive for soluble rocks and corrodes the walls.
