Carbondioxide

It is a colorless, odorless, tasteless and non-toxic gas that can be easily liquefied. It has an important place in the life cycle; Humans and animals give off CO2, plants breathe this CO2, give off oxygen. It sublimes at the boiling point, that is, it goes directly from the solid state to the gas phase. The solid state of carbon dioxide is called dry ice.

Properties of Carbon Dioxide

• It is heavier than air.
• It is an odorless and colorless gas. Carbon dioxide gas has a higher concentration of acidic odor.
• Its molecular weight is 44.01 mol/gr.
• It shows boiling feature at -78 degrees.
• It has a specific heat of 850 j/kg at 1 atmosphere pressure and 25 degrees temperature.
• It has an expansion volume of 629 units under 1 atmosphere pressure.
• It has a critical temperature of 31 degrees. It has a critical pressure of 73.82 bar.
• It is solid at low temperatures. This condition is called dry ice. Dry ice; It has non-flammable, taste and odorless properties and non-toxic effects.
• Carbon dioxide is toxic in gaseous form. It has a particularly suffocating feature. Deaths from carbon dioxide are due to the suffocating effect of the gas.
• CO2 is represented by the chemical symbol in the periodic table.

How it is made?

There are 4 different production methods of carbon dioxide production. These are:

• Obtaining from Natural Resources: It is obtained from underground resources. An abundance of this gas is found at the mouth of craters in volcanic regions and in the sea.
• Obtaining Carbon Dioxide Gas by Dry Ice Production: Dry ice is obtained during the production of many materials. Dry ice is the frozen form of carbon dioxide gas. Dry ice can be obtained by directly freezing the carbon dioxide formed as a result of the activities of some living things. Production quantity is limited.
• Obtaining Carbon Dioxide by Combustion of Hydrocarbon Compounds: Carbon dioxide gas is obtained by burning substances such as petroleum, sulfur and nitrogen. These hydrocarbon compounds are abundant in petroleum-type products.
• Production from Flue Gas: Iron – Steel factories, natural gas and electricity generation facilities can convert CO2 out of their chimneys into liquid phase by capturing it.

Uses of Carbon Dioxide

• Carbonated beverage production, carbonation
• Protective gas in food production, refrigeration, freezing, packaging.
• Waste water treatment, neutralization of alkaline waste water
• Metalware manufacture, to generate shielding gas in the welding process.
• Growing plants, enriching the greenhouse atmosphere
• Paper and pulp production
• Extraction, decaffeinated coffee production
• Fire fighting, carbon dioxide fire extinguishers
• In popping candy production
• Brake lining sprays, propellant in deodorants

Supply Forms and Cylinders

Carbon dioxide gas can be filled as a liquid into steel drawn cylinders. For this reason, it can be filled from 5 Lt cylinders to 600 Lt cylinder bundles, and can be shipped with fixed tanks if requested in higher volume containers.

How to Use, What Should Be Considered During Use?

• Carbon dioxide gas is a cold gas, so if it is in contact with the skin for a certain period of time, it can cause cold burns.
• While the carbon dioxide gas installation is being made, the necessary calculations should be made according to the temperature and pressure curves between the gas-liquid phase and the installation should be done.
• If the use of liquid carbon dioxide is to be used in cylinders where there is demand, there must be siphon cylinders.
