Impact of moisture on the corrosion behavior of copper and mild carbon steel in corn biodiesel
Presence of moisture is very important for vegetable oils and for corresponding biodiesel because it may cause some problems or accelerate some issues that cannot be ignored.
biodiesel is its hygroscopic nature, which accelerates the corrosion of the fuel system of the engines.
The Effects of Corrosion
Preventing corrosion has become a lucrative industry. No one wants to drive in a rusted car if they can help it. But corrosion is more than just a cosmetic concern.
Corrosion can be dangerous if it affects infrastructure such as buildings, bridges, sewage pipes, the water supply, ships, and other vessels.
Corrosion can cause infrastructure to weaken, putting lives at risk. So, while corrosion prevention may be costly, it certainly is necessary.
There are two different methods employed in corrosion protection, including:
1. Physical corrosion protection (essentially the withdrawal of humidity)
Transport packaging in the form of PE-bag usually in combination with desiccants
Aluminium foil in combination with desiccants
2. Chemical corrosion protection (modification of the physical process)
Oils and fluids
Acids and bases
Corrosion Protection Inhibitors (VCI films, VCI papers, VCI cardboards, etc.)
Protective gases (oxygen scavenging and ethylene absorbing)
