Le CO₂ impliqué dans ce phénomène provient du méthane (CH₄) contenu dans le gaz naturel traité par le TEG. Lors du avec le TEG, le gaz naturel peut contenir des traces de CO₂ qui ne sont pas totalement éliminées en amont, et qui, en présence d’eau, favorisent une corrosion acide.
Le phénomène de corrosion peut être décrit par les réactions suivantes :
Origine du CO₂ :
Lors du traitement du gaz naturel, le méthane contient des impuretés telles que le CO₂, qui peut rester dissous dans le TEG.
Dissolution du CO₂ dans l’eau :
CO2+ H2O → H2CO3 (s)
L’acide carbonique ainsi formé se dissocie en ions hydrogène et d’ions bicarbonate, acidifiant le milieu :
H2CO3(s) → H++HCO3−
Corrosion du métal :
L’acidité du milieu dit agressive favorise la dissolution du fer selon :
Fe(s) + 2H+→ Fe2+ + H2
Précipitation de la sidérite (en présence d'ions bicarbonate) :
Fe2++HCO3− → FeCO3 (s) + H+

Over time, the surface of the bottle reacts to moisture and minerals, creating iridescent patches. You’ll see metallic-like colors, like blues, greens, or browns, spreading across the surface, creating a weathered, aged effect. The texture might also look slightly rougher or uneven in places, adding to the appearance of deterioration.swaracool

"Aerial view of a large industrial building with a steel flat roof during light rain, showcasing multiple roofing issues. Water pools in several low spots, reflecting the overcast sky. Rust spreads from loose fasteners, creating orange-brown stains. Visible gaps in seams between metal s allow water to seep through. Around vents and chimneys, cracks in sealant and peeling flashing are evident. Some metal s show slight buckling from thermal expansion, creating wavy patterns. Small dents from hail or debris impact dot the surface. One corner of the roof, near the coast, shows advanced corrosion with flaking paint and pitted metal. Along the edges, improperly installed flashing hangs loose, exposing the roof's vulnerable points. Workers in safety gear inspect a particularly damaged section, their yellow jackets contrasting against the gray metal. In the background, dark storm clouds approach, threatening to exacerbate the existing problems."ipadesign

Create a detailed scene of a rusted, partially damaged oxygen tank resting on the rocky floor of an underwater cave. The oxygen tank should have visible scratches, faded paint, and algae growing on its surface, indicating long-term exposure to the deep-sea environment. Its pressure gauge should be cracked but still faintly glowing, suggesting it might still function. Surround the oxygen tank with scattered debris, including broken glass, rusted tools, and small pieces of coral. The underwater lighting is dim, with shafts of light filtering through cracks in the cave walls, and particles floating in the water. Bioluminescent plants and soft glowing fungi in the background create an eerie yet captivating ambiance, blending the themes of decay and survival.huaaazii
