Question

in boiler corrosion dissolved co2 can be removed by adding​

Answer 1

Answer:

PREVENTIVE MEASURES:

Eliminating corrosive gases.

Removal of dissolved oxygen.

High PH value of boiler water.

Mechanical deaeration of boiler water.

Higher feed water temperature i.e. reduces its oxygen content.

Chemical de-oxygenation by use of oxygen scavengers i.e. sodium sulphite.

Answer 2

In boiler corrosion dissolved CO₂ can be removed by chemical de-oxygenation by use of oxygen scavengers i.e. sodium sulphite.

• The most cost-effective technique to remove free carbon dioxide from water is to use a process known as "Decarbonization," which is also known as "Degasification."
• The decarbonization method will reduce CO2 levels by 99 percent or more.
• The main impact of dissolved carbon dioxide is corrosion.
• When the gas dissolves in water, it produces corrosive carbonic acid.
• The low pH produced by this reaction also increases the corrosive impact of oxygen.
