There are two different materials on the market today which are being used with good results. These are the neutralizing amines, and the filming amines.

The neutralizing amines are volatile alkaline materials. They are primarily effective against carbon dioxide corrosion, but have very little value in combating oxygen corrosion. In your raw water are naturally occurring bicarbonates. As these pass through the heater and into the boiler they are converted to caustic soda. Carbon dioxide gas is given off as a result of this conversion and it passes out of the boiler with the steam. Carbon dioxide is an acid and it dissolves in the condensate as it is formed. This lowers the pH of the condensate to a point where actual acid attack of the pipe occurs. The neutralizing amines simply neutralize this acid.

If soda ash is used for boiler water treatment it too breaks down in the boiler to form caustic soda and carbon dioxide. This simply increases the corrosion problem, and, if you are using a neutralizing amine it increases your cost. Inasmuch as caustic soda is already reverted to the final pro- duct, no carbon dioxide is given off in the boiler. This is of course the ad- vantage of caustic over soda ash.

Filming amines actually protect the pipe by forming a thin, non-wetable coating on the surface. This separates the pipe from the corrosive condensate and offers excellent protection from both carbon dioxide and/or oxygen corrosion. The filming amines represent a far better material in almost every case. Not only do they provide better protection, they usually cost less as well!

The filming amines cannot be mixed with other chemicals, and pure condensate must be used to prepare the feeding solution. However, the filming amines can be fed to the boiler by means of the boiler feed water. it is not necessary to feed it into the steam line.

The filming amines have a strong affinity for iron. Therefore they will clean off all of the corrosion products, dirt, and oil that might be inside your condensate return system. This may give some trouble with plugged traps and strainers until the system is cleaned out.

Define different type of corrosion and explain electrochemical theory of corrosion.how will you protect corrosion?

Types of corrosion 1. Induced corrosion due to chloride 2. Pitting 3. Corrosion due to Oxidation 4.Corrosion is due to dissimilar materials 5. Corrosion due to imbalanced electrovalency In Electro-chemical theory,when two materials of different potential are in contact with each other through electrolyte, the two materials become, one is cathode and the other anode. The ions(electrons ) passes from anode deposited on cathode. Protection methods: 1.Metallurgical method 2.Corrosion inhibitors 3 Coatings like paintings, epoxy application etc 4. Cathodic protection 5 Galvanisation 6 Balancing of of electrovalency of materials or reducing impurity 7 use of sacrificial anode

How could you prove that the liquid condensing from exhaled air is water?

you can prove that when you exhale,water is released. hold a mirror up to your mouth.Breath onto the mirror.Describe what you see in your notebook.Then,explain how you have proven that when you exhale, water is released.


Explain dry corrosion with an example?

Dry corrosion, also known as atmospheric corrosion, occurs when metal is exposed to oxygen in the air without the presence of moisture. This process can result in the formation of oxide layers on the metal surface, leading to rusting or degradation. For example, iron exposed to dry air can form iron oxide (rust) over time, weakening the metal and affecting its structural integrity.


How can explain liquors as an example of chemistry?

Liquors must be distilled, and distillery is a chemical process.

Explain why winter's car engine may be damaged if antifreeze is not added to the water in its cooling system?

When water freezes it expands ( hopefully the freeze plugs will pop out and your engine block won't crack ) It's best to run a 50 / 50 mixture of antifreeze and preferably distilled water year round because it provides freeze protection , boil protection and also corrosion protection ( although the corrosion protection does not last forever , the antifreeze needs to be changed periodically ) Don't exceed 60 % antifreeze in the mix )

What type of water has natural protection?

I think I know what you're trying to ask, but I'm not sure. Your question is about the chemical properties of water, but I don't understand what you mean by "natural protection." If you would explain to me what you mean by that, I could understand your question better.
