Carbon dioxide CO2

ABOUT CARBON DIOXIDE GAS

Carbon dioxide gas is obtained naturally from underground or from waste flue gas. Carbon dioxide gas exists simultaneously in solid, liquid, and gaseous states at -56.6°C and 4 bar pressure. Liquid carbon dioxide can be stored in Kryogenic tanks or in single-walled, internally cooled systems insulated with horizontal or vertical insulation materials. Carbon dioxide is stored at a pressure of 13–20 bar and a temperature of -35°C to 55°C and is transported by truck.

Carbon dioxide is a corrosive gas. Normal materials are suitable for dry gas at ambient temperature. Below -30°C, only low-temperature carbon steel, austenitic stainless steel, aluminum, copper, and alloys of these two are suitable for use. If carbon dioxide dissolves in water in an oxygen environment at high pressures, it is appropriate to use carbon acid-resistant materials.

NATURAL CARBON DIOXIDE

Natural carbon dioxide is obtained from underground sources. In Turkey, it is mainly produced in the Denizli Kızıldere basin, the Niğde Kemerhisar basin, and the Aksaray basin. First produced naturally in the 1990s, carbon dioxide was produced in the Niğde basin by Güney Doğalgaz.

Natural carbon dioxide in the world consists of four main origins (sources):

1. Magmatic origin formation

2. Metamorphic origin formation

3. Geothermal origin formation

4. Sedimentary origin formation

PHYSICAL CHARACTERISTICS

Molecular weight: 44.01 g/mol

Density (liquid, at -56.6°C): 1.1778 kg/dm³

Density (gas, 0°C, 1 atm): 1.97 kg/m³

Critical temperature (1 atm): 31.1°C

Sublimation temperature: -78.50°C (transition from solid to gas phase)

It is a colorless, odorless, non-toxic gas that is heavier than air.

IMPORTANT POINTS TO CONSIDER

Carbon dioxide gas is suffocating. It is 1.53 times heavier than air. The occupational exposure limit (TLV) is 5000 ppm. Carbon dioxide does not exist in liquid form at atmospheric pressure, but it can exist in liquid form in a closed container at 4 bar. The solid phase of the gas is called dry ice, which can cause frostbite on the skin. The atmosphere contains approximately 0.035% carbon dioxide.
